There's a cadre of people who get really far out into adventure riding that it's basically a small step away from needing a mountain bike. There are also lots of people who want the absolute fastest road bike available. Those ends of the spectrum don't represent the vast majority of riders though. Most people have a lot less focus and need a good, versatile bike that just works. We included the Trek Checkpoint on our list of the best gravel bikes available because that's exactly what you get, a bike that just works. 

The Trek Checkpoint is a bike that I have held onto for close to a year. It carried me across thousands of miles and all kinds of weather. I've had adventures on and off the road and I've put the bike to the test in every type of riding I could think of. After all this time, I'm ready to discuss the experience, what I like about it and where it falls short. If you've been considering a new gravel bike keep reading to see if the Trek Checkpoint is the right choice for you.

Design and aesthetics 

In many ways the Trek Checkpoint is a fairly uncomplicated design. The biggest standout design feature is the rear IsoSpeed decoupler system but even that piece, at least in the SL, sticks to the less complicated version. Trek refers to this version as the "seat tube IsoSpeed" and it refers, as expected, to the seat tube alone. There's no adjustment, nothing to think about, and just an isolation of the seat tube from the structure of the top tube and the seat stays. The end result is a passive suspension design that relies on flex in the 500 series OCLV carbon. 

To further exaggerate the effect, there's a prominent cutout near the bottom of the seat tube. The cutout doesn't reroute the tube for better aerodynamics but instead narrows the tube. The narrow point becomes the fulcrum and the rest of the tube has room to move around. If you want to add even more passive suspension, the non-proprietary round seat post means there's plenty of opportunity to take advantage of aftermarket seatposts. Something like the Ergon CF Allroad Pro Carbon seat post is an easy swap, further emphasising how uncomplicated the design of the Checkpoint is. 

There are a few other smart little design features as well. Details that continue to keep it simple but functional like the in-frame storage. Behind the water bottle mounts on the downtube is a lever that opens up a space at least as big as your typical flat repair kit. There's a bag that makes sure anything in the space doesn't rattle and the back of the door has room for the Bontrager Bits Multi-tool. 

On the other side of the down tube is where you'll find the carbon armour. This amounts to plastic cladding permanently attached to the lower section of the downtube. It's once again simple but important. Unfortunately, there's no matching armour on the rear chain stay but what you will find is a water bottle mount in the carbon armour. 

The under-the-downtube water bottle mount is just the tip of the iceberg when it comes to mounting points. There are two standard water bottle mounts, that one under the downtube, and an extra three mounting points higher up the downtube. If you aren't running frame bags that's room for an extra water bottle but there are also three mounting points under the top tube. The Bontrager adventure frame pack, on our list of the best bikepacking bags , will attach to the frame without straps using these mounting points. That still leaves an extra pair of mounting points on the upper portion of the top tube for a bolt-on top tube pack. 

The SL version of the Trek Checkpoints goes even farther with mounting options. While the SLR build gets the lighter 700 series OCLV carbon it also does with "only" the fourteen frame mounting points. Sticking to the SL models means there are also three extra mounting points on each side of the fork. Both models also have the option of fitting real mudguards and the Bontrager NCS Alloy Fender Set is one of best out there although there are also other options on our list of the best mudguards . 

Like the design features, the aesthetics of the Checkpoint differ a bit throughout the lineup. The top-shelf SLR 6, 7, and 9 are where you'll find the most colour options while lower down the line the ALR and SL models have only one or two colours depending on the specific build. In the case of the SL 6 eTap here, the only colour available is a deep red Crimson/Carbon Red Smoke that dips the bulk of the frame in a rich high-gloss blood red. There are metallic flakes throughout and a geometric pattern at the downtube and forks with a few details in a darker smoked red. 

The Trek Checkpoint lineup is extensive to the point of confusion. Right now, there are 12 different models listed with three frames serving as the building blocks. Serving as the entry-level models, the aluminium ALR frameset gives less expensive options with two builds before moving up to the carbon SL models. All using the same 500 series OCLV carbon, the SL models have three builds. These are less expensive than the SLR models but also focused more squarely on bikepacking with additional fork mounts. At the top of the lineup, the four SLR models switch to the lighter 700 series OCLV carbon and they also lose the fork mounting points. 

The SL 6 eTap that we spent our time with represents a middle-of-the-lineup option and costs less than half the price of the top model. The groupset is SRAM Rival AXS with 12 gears across a 10-44 cassette and a 40-tooth front crankset. The frame works with 1x or 2x but if you want a front derailleur you'll have to decide if you'd prefer to move up or down. Down drops to 11-speed GRX while up gets SRAM Force AXS Wide but also packages carbon wheels and represents a significant price jump. 

Instead of the carbon wheels on the more expensive SL 7 eTap, the 6 comes with the alloy Bontrager Paradigm Comp wheelset. While not a particularly high-end wheel these check all the boxes with a centre lock disc interface, 25mm internal width, and tubeless compatibility. Thru axles are standard bolt-through in 12x142 and 12x100 and the included tyres are Bontrager GR1 Team issue in a conservative 700x40mm width. There is space for up to a 45mm tyre if you find yourself looking for more off-road capability. 

For the touchpoints, expect Bontrager pieces. The saddle is a short nose Bontrager Verse Comp with steel rails and it's supported by is a 27.2mm carbon piece also from Bontrager. At the front of the bike the bars are the rather unique Bontrager Elite Gravel bars that we feature in our best gravel handlebars list. They have an integrated foam padding to help ease the rough roads and come paired with a shorter than standard Bontrager alloy stem.  

Performance

As a journalist who writes about cycling technology, I have an attraction to exotic tech in bikes. The new Trek Madone with a chunk missing from the seatpost sounds interesting. Or, if we are talking gravel, maybe a single-sided Lefty suspension fork like the Cannondale Topstone I previously spent time on. The wilder the better for me both because of my job and because that's my personality. 

The problem is that those kinds of bikes can be difficult to live with. The higher the integration and the more proprietary the pieces, the bigger the challenge. For example, the Lefty fork is amazing at what it does but if I want to drive to a ride with a friend I have to ask what kind of rack they have. If it's a fork-mounted version, then it won't work for me.

Then there's the Trek Checkpoint SL 6 eTap and its distinct lack of fancy technology. On paper, it's almost a boring bike but when people ask me for a bike recommendation, it's often my go-to choice. There are mounts everywhere, including for mudguards and it will do whatever you ask of it. I got the Checkpoint, added Garmin power pedals and swapped the saddle to an Ergon SR Allroad Core Pro, and proceeded to ride it for thousands of miles without ever having an issue. When winter hit, I added mudguards and rode through the winter spending seven hours at a time in constant rain every weekend. I never once had to mess with seat post issues or creaky bearings, everything just worked. 

I changed wheels and handlebars because I was testing things but the stock pieces were fine. The groupset in particular is a highlight and has become my gold standard example of why 1x12 might make sense for everyone. Rival has worked flawlessly and while 11-speed 1x gearing occasionally leaves me searching for gears, 1x12 has everything I need. The 40-tooth front and 44 rear works for climbing on loose surfaces, even with a loaded bike, but has plenty of gearing for road riding too. Every now and then I spin out when descending and chasing someone but it's rare and I prefer to have the climbing gears. 

When asked, I tell people you can walk out of the store with an SL 6 eTap and there's nothing you need to swap. The wheels aren't light, or fancy, but they work just fine. Same with everything else except the stem. One of the headline details about the Trek Checkpoint is the geometry that uses a short stem and a long wheelbase and right away I found it annoying. I swapped to the Trek RSL stem in a 100mm length as soon as possible. I noticed no lack of stability but I did stop banging my knees on every hill. 

Other than the stem, the Checkpoint has never left me asking for more. During the winter I would come home freezing and drenched with a bike caked in mud. I didn't wash the bike and at one point the brakes only alerted me to an issue when the pads ground down to the metal backing. Despite the lack of maintenance the groupset, wheels, and frame haven't needed anything. If I want to go bikepacking, I will never need to get creative with mounting. If I want to use the Checkpoint as a road bike, a tyre swap will have it ready to go. 

There are bikes that excel at a particular thing. You can get as specialised as you want in whatever area appeals to you and you can collect a quiver of bikes that you choose between depending on what's on the menu that day. Or you could get a bike like the Trek Checkpoint SL 6 eTap that just works no matter what you want to do. 

The Checkpoint might be a gravel bike but that's far from all it offers. Swap to a 28 or 30mm tyre for road riding and it's perfectly capable of keeping up with whatever group you want to ride with. If a summer gravel race catches your eye, swap on a 40mm tyre and only your legs will keep you off the podium. For a more relaxed pace bikepacking weekend, a 45mm tire might be a good option and you can load up all the mounts with every bag you can think of.

The only real question is which of the many build options makes sense. The SLR frameset is lighter but it's also a lot more expensive and it lacks mounting points on the fork. The SL 5 build gets you all the mounting points at a lower price but it’s also an 11-speed mechanical build with narrower wheels. If you are looking to save money look to the aluminium frameset options and if you've got a bit more money to invest, the Trek Checkpoint SL 6 eTap represents a do it all bike that balances price and performance.

Trek Emonda SL 6 Pro 2021

First up, the comfort.

I picked up on the fact that the SL6 Pro has quite a firm ride – a little bit old school, dare I say. By that I mean that a lot of carbon fibre frames have become much more comfortable over the years as designers and manufacturers have learnt about carbon fibre grades, tube profiles and, more importantly, the layup of the composite material.

The Cube Attain GTC SL I tested recently highlighted this in the way that it really managed to reduce road buzz while retaining plenty of feedback through the frame and fork.

2021 Trek Emonda SL 6 Pro - riding 3.jpg

This isn't a criticism of the Trek at all, it just wasn't quite what I was expecting. I like it; I'm a big believer in ultimate performance over comfort when it comes to race bikes, and that is exactly what the Émonda delivers.

Stiffness throughout the fork and the lower half of the frame is very impressive, and means the Trek is responsive to your inputs. The wide bottom bracket shell allows for a large down tube and chunky chainstays to reduce flex when you are really nailing it, while the front end backs this up via the tapered head tube and firm fork legs. Sprinting and climbing are all taken in the Émonda's stride.

2021 Trek Emonda SL 6 Pro - UCI badge.jpg

As you'd expect from a race bike, the riding position can be set up to be pretty aggressive – with a relatively short 151mm head tube length on this 56cm model I could achieve a low handlebar-to-saddle drop to aid the aerodynamics, especially when in the drops.

2021 Trek Emonda SL 6 Pro.jpg

The rest of the geometry follows the same theme with a 73.5-degree head angle and a relatively short wheelbase for a disc-equipped frame (the chainstays are often a fair bit longer than those on rim-braked frames because of the extra axle width at the rear dropouts) at just 983mm.

Trek has achieved a good balance here with the Émonda I reckon.

The shorter wheelbase makes it nippy, which allows for snappy direction changes at high speed, yet it's managed to tame the handling just enough that the Émonda never becomes a handful unless you do something really stupid.

2021 Trek Emonda SL 6 Pro - riding 4.jpg

In my First Ride piece I mentioned that I hadn't managed to point the Trek at my favourite test hill, one that is fast and twisty with off-camber bends and chicanes. It really tests every part of a bike's handling in a blur.

Well, I have now, about five or six times, and the Émonda really impressed. It has the quickness in the steering and the overall agility to be pushed very hard into the corners.

After a night of heavy rain, gravel had been washed out into the lane slightly out of sight as I went into a fast left-hander at about 45mph; I dabbed the brakes a little, but seeing the grit and stones spanning the entire road there was no real way out of it. Letting the bike hit the gravel and predicting where the slide was probably going to end was the only option, and it was a sketchy couple of seconds.

As the front tyre regained grip on the asphalt there was a second where the still-sliding rear wanted to get in front, but the Trek's well-balanced handling allowed me to quickly regain control and blast to the bottom of the hill.

In less extreme circumstances the Émonda is an absolute hoot to ride downhill, with just slight adjustments to body position and the handlebar allowing you to flow from corner to corner.

2021 Trek Emonda SL 6 Pro - riding 1.jpg

On longer rides the Trek is just as well mannered; it is a very easy bike to ride quickly even when fatigue can kick in or when you are on unfamiliar roads.

The stiffness I mentioned earlier doesn't come through as a negative on higher mileage jaunts, especially if you get on with the saddle and have a decent pair of shorts on. The three- to four-hour rides I used the Trek on were a lot of fun. Unleash the power for the fun bits and then when you are on the flat, straight slogs you can just hunker down and keep the pedals turning over.

2021 Trek Emonda SL 6 Pro - riding 6.jpg

The only thing I needed to do was to shift the saddle 5mm closer to the bar than I would normally have it, because of the width of the top tube as it flows into the seatstays either side of the seat tube. I have quite large thighs and I could feel them rubbing on the frame every pedal revolution when I first started riding the Trek.

2021 Trek Emonda SL 6 Pro - top tube shape.jpg

Frame and fork

The Émonda has always been the lightweight bike of Trek's road range, leaving outright speed to the Madone, but for this latest model Trek has incorporated more aerodynamic profiles in the Émonda's design.

2021 Trek Emonda SL 6 Pro - down tube.jpg

Unlike most aero bikes, though, the Émonda's frame doesn't focus on being fast in a straight line or at high speed, it is a climbing bike after all. Instead the engineers have focused on 'unsteady aerodynamics', which fit in with the much lower speeds found when ascending.

2021 Trek Emonda SL 6 Pro - riding 7.jpg

Most of the attention has been placed on the front end, including the head tube and down tube. The top-end SLR models use the Bontrager XXX aero handlebar/stem combo which further increases the benefits, but that isn't available on the SL options.

2021 Trek Emonda SL 6 Pro - head tube.jpg

The SLR models also use a new OCLV 800 grade carbon fibre while the SLs use the 500 series, which increases the weight a bit, although a claimed frame weight of 1,142g and 380g for the fork is far from shabby.

2021 Trek Emonda SL 6 Pro - frame detail.jpg

If wind cheating is your main goal then it's worth noting that the Émonda is optimised for 25mm tyres, as that is the most common size used for racing, but if you want something a bit wider 28mm will fit while still allowing 6mm of space around the tyre.

2021 Trek Emonda SL 6 Pro - clearance.jpg

As you'd expect on an aero-based bike, the Émonda has full internal cable routing but this is taken to an extra level compared with most frames, with the cables and hoses leaving the handlebar and entering the frame through the spacers rather than the head tube or down tube. This gives much cleaner lines at the front.

2021 Trek Emonda SL 6 Pro - steam detail.jpg

You won't find a standard seatpost either. The Émonda's seat tube continues up past the top tube by a fair old way and then an external seat mast is placed over the top; you tighten the hex bolt to clamp it into place at the right saddle height.

2021 Trek Emonda SL 6 Pro - seat post.jpg

The Émonda range is now completely disc brake-equipped which to my mind is a bit of a shame as I am a big fan of rim brakes, and it would certainly bring the weight down for a bike aimed at climbing.

2021 Trek Emonda SL 6 Pro - front disc brake.jpg

Many manufacturers are seeing sales of disc models outstripping rim options by a large margin, though, so it is kind of inevitable. There is also the cost – the Émonda is available in seven sizes so that'd be 14 different moulds required if Trek offered both brake options.

2021 Trek Emonda SL 6 Pro 2.jpg

The Émonda comes with flat mounts, as you'd expect, and 12mm thru-axles front and rear.

2021 Trek Emonda SL 6 Pro - rear disc brake.jpg

I mentioned the wide bottom bracket shell earlier and this is normally only achievable by using a press-fit BB, where the bearing cups are pressed into the frame. If tolerances aren't adhered to, creaking can occur, especially after water or grit gets between the mating faces, which is why we've seen many brands return to external threaded options.

2021 Trek Emonda SL 6 Pro - bottom bracket.jpg

Trek has gone for what is possibly the best of both worlds with the T47 system. First introduced by Chris King and Oregon's Argonaut Cycles , they thread into the bottom bracket shell which allows it to be wider, increasing stiffness without affecting the width between the pedals (Q-factor).

2021 Trek Emonda SL 6 Pro - bottom bracket 2.jpg

If you want a more in-depth look at what changes and design tweaks were made to achieve this new Émonda frameset then it'd be worth checking out Mat's full breakdown here .

Wheels and tyres

Trek says that the SL 6 Pro comes with all the lightweight components you need as standard, so there is no need to upgrade. You could save a few grams here and there, but overall it is a pretty complete package.

This model is the first carbon bike in the line-up that comes with a set of carbon fibre wheels. The 35mm Bontrager Aeolus Elite 35s are 35mm deep and are tubeless ready.

2021 Trek Emonda SL 6 Pro - wheel and tyre.jpg

It's a good set of wheels for a whole range of riding styles: shallow enough to work on the climbs and just about deep enough to give you a small aerodynamic gain without being affected by crosswinds. Comparing the price of the near-identical SL 6 suggests you are getting them for just £450 too.

Reliability isn't an issue as they took on everything that was put in their way over the test period, and should anything happen and they get damaged Trek will replace or repair them for free in the first two years of ownership.

2021 Trek Emonda SL 6 Pro - rear hub.jpg

Wrapped around the wheels are a pair of Bontrager R2 Hard-Case Lite tyres. They are all right in terms of rolling resistance, grip and durability, but their 60tpi casing does give them a bit of a 'wooden' feel. You aren't getting a whole lot of suppleness which would really benefit the frameset, so I'd definitely upgrade when they wear out.

I've been using the R3 Hard Case Lites recently and they are a much better tyre, so something like that would be a good upgrade if you want to keep the Bonty/Trek theme going.

Drivetrain and brakes

On the SL 6 Pro, Trek is giving you a full Shimano Ultegra hydraulic/mechanical groupset and it suits the bike very well. You are getting near-Dura-Ace performance but at a much reduced price.

2021 Trek Emonda SL 6 Pro - crank.jpg

Trek has specced a 52/36-tooth semi-compact chainset and an 11-30 cassette, which is a great choice of gear ratios for a bike of this style. There are plenty of top end gears for speed work while the 30-tooth sprocket will give you an extra bailout gear over the more usual 28T found on the majority of race bikes.

The gear shifts from Ultegra are top notch. You get quite a light feel at the levers, but one that also gives a very nicely defined click so you can be sure that the shift has taken place.

2021 Trek Emonda SL 6 Pro - bar and lever.jpg

When it comes to the braking, Trek has chosen to fit 160mm rotors front and back, which give more than enough power for a bike of this type.

Shimano's hydraulic systems are very powerful but also easily modulated thanks to loads of feel through the levers, allowing you to stop quickly without the fear of locking up the front tyre, even in the wet.

Finishing kit

All of the finishing kit is supplied by Bontrager, Trek's in-house parts department, and it's all decent quality stuff.

The handlebar is the Bontrager Elite VR-C which is an aluminium alloy model with a short reach and a shallow drop, making it ideal for a whole host of different riders' proportions. Helping that is the fact that different size frames get a different width bar, ranging from 38cm up to 44cm.

2021 Trek Emonda SL 6 Pro - bars.jpg

It's the same for the Bontrager Pro stem: the smallest 47cm bike gets a 70mm unit, with the 62cm extending that out to 110mm. The stem on each frame size seems to come up a bit shorter than most bikes of this type, but it seems to work.

2021 Trek Emonda SL 6 Pro - stem.jpg

I got on fine with the Aeolus Comp saddle. Its shape is well suited to riding hard and fast, and I like the firm padding which gives you a good platform to push against when you are really hammering it. (There's a separate review of it here .) 

2021 Trek Emonda SL 6 Pro - saddle.jpg

This SL 6 Pro model has an rrp of £3,350, which isn't a bad deal for what you are getting here with the aero carbon frame, fork and deep-section wheels.

The similarly themed Scott Addict RC 30 is £3,199 and also come comes with an Ultegra groupset, but it is begging for an upgrade to the wheelset. It is light, though, at just 7.88kg.

If it's aero that you want then there is the Orro Venturi . The closest model in price is £3,299.99; you only get alloy wheels, but you are getting Ultegra Di2 for the gear shifting.

Overall, the Émonda is a very good bike. The aero tweaks have turned it into a very fast and efficient bike that still manages to deliver on the weight front and this SL 6 Pro model is so well specced there's no need to update anything when it comes to the components, just the tyres when they wear out.

A quality frameset that works both on the flat and the climbs, and well specced for the money

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Trek says, "Émonda SL 6 Disc Pro is the first carbon road bike in the line-up that gives you lightweight carbon wheels to match your lightweight frame. Aero tube shaping, disc brakes and a high-performance drive train make it a great option for roadies who value great handling and lots of speed."

Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options

There are five models in the range starting with the SL 5 which comes with a Shimano 105 groupset for £2,725, finishing off with the SL 7 with SRAM eTap at £5,250.

A frameset is also available for £2,200.

Tell us about the build quality and finish of the frame and fork?

A well made and finished frame and fork.

Tell us about the materials used in the frame and fork?

Frame – Ultralight 500 Series OCLV Carbon, Ride Tuned performance tube optimisation, tapered head tube, internal routing, DuoTrap S-compatible, flat-mount disc, 142x12 mm thru axle

Fork – Emonda SL full carbon, tapered carbon steerer, internal brake routing, flat-mount disc, 12x100 mm thru axle

Tell us about the geometry of the frame and fork?

The geometry is race orientated with a steepish head angle and a short head tube length.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

The stack and reach figures are pretty typical for this size and kind of bike. This 56cm comes with a stack of 563mm and a reach of 391mm.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

Overall it's fine, although it does have a firmer ride than a lot of new carbon fibre frames.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Stiffness is very impressive, especially around the bottom bracket area.

How did the bike transfer power? Did it feel efficient?

Efficiency is very impressive, it is a proper point and shoot bike.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

How would you describe the steering? Was it lively neutral or unresponsive? Responsive.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

The handling is very well balanced, making the Trek easy to ride whether you are just cruising along or pushing it hard through the bends.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

I liked the saddle, it was firm yet comfortable for all sorts of rides.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

The Bontrager wheels offer loads of stiffness even when riding hard, out of the saddle.

Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?

I'd change the tyres for something a little more supple which would help you achieve higher speeds in the bends.

The drivetrain

Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?

The Shimano Ultegra groupset can't really be faulted. Gears and brakes offer great performance and reliability.

Tell us some more about the wheels.Did they work well in the conditions you encountered? Would you change the wheels? If so what for?

It's good to see a quality set of carbon wheels on a bike as standard at this price. They performed well in all sorts of conditions and seem to be durable.

Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so what for?

The Bontrager R2s aren't bad, but the SL 6 Pro deserves something faster and grippier.

Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?

Decent quality in-house kit that suits the bike well.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

How does the price compare to that of similar bikes in the market, including ones recently tested on road.cc?

For a semi-aero bike the Émonda is pretty well priced, like against the Scott and Orro mentioned in the review.

Use this box to explain your overall score

The Émonda's new aero frameset means that not only is it a good climber, it also works well on the flat sections too. The overall quality is very good and you are getting a well chosen spec. The firm ride might not be ideal for those who focus more on comfort, though.

Overall rating: 8 /10

As part of the tech team here at F-At Digital, senior product reviewer Stu spends the majority of his time writing in-depth reviews for road.cc, off-road.cc and ebiketips using the knowledge gained from testing over 1,500 pieces of kit (plus 100's of bikes) since starting out as a freelancer back in 2009. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy. With a background in design and engineering, he has an obsession with how things are developed and manufactured, has a borderline fetish for handbuilt metal frames and finds a rim braked road bike very aesthetically pleasing!

Not a big fan of the way the cables and hoses run at the front of the bar in order to fit under the stem like that, I'm surprised they haven't gone for a system where they run intrnally then under a stem cover etc

Quite a lot of money for an 8.2 kilo bike. 

"Comparing the price of the near-identical SL 6 suggests you are getting them for just £450 too."

The side by side comparison of the SL6 and the pro makes them identical bar the wheels. Which listed on the trek website retail at a price difference of £250, not £450. So either the stock wheels on the SL6 are over priced on their own (then maybe the bike is too) or the only reason to buy the pro is if the Aeolus are the wheel upgrade you want over everything else on the market.

I'm still more inclined to the RC30.

The Trek Domane SL 6 Can Glide Over Any Road Surface

With its own IsoSpeed suspension system, this versatile road bike is a winner for ride quality and value

Price: $3,200 Weight: 17.1 lb. (56cm) Use: Road

Trek Domane SL6

The Domane SL and SLR Family The Domane SL family starts with the SL 5 (in unisex and women’s versions), with rim brakes and a full Shimano 105 groupset, and tops out at the SLR 9 Disc, a $12,000 bike with full Shimano Dura-Ace, Di2, hydraulic disc brakes, and Aeolus 3 D3 Disc carbon wheels. The SLR models offer additional clearance for up to 32mm tires; all the bikes have front and rear IsoSpeed, which offers the patented road-damping technology that we love so much about this series. The SLR 6 comes in a disc-brake model and a disc-brake gravel version with wider, burlier tires. The SL 6 is a more budget-friendly version in the line, but it still brings the comfortable ride geometry and road suspension these bikes are known for. And, with a full Shimano Ultegra groupset, it has the distinct component advantage over the SL 5.

Trek Domane SL6

The Secret to Those IsoSpeed Decouplers The SL 6 has a lightweight carbon frame and a front and rear suspension system, called IsoSpeed, that allows it to effectively soak up road noise. Here’s how it works: The front IsoSpeed decoupler on the bike makes it so the steerer tube can flex independently from the head tube, which allows the bike to reduce road vibration. The rear IsoSpeed decoupler has a slider that lets you adjust the compliance level for terrain and personal preference by up to 14 percent. You might not even need to adjust the rear slider to experience the road-smoothing effects of the two decouplers working together—we found that the all-over effect of the bike was fast and smooth performance equally suited to asphalt and cobbles.

RELATED: Trek Finally Launches a True Gravel Bike

Other Component Highlights The full Ultegra drivetrain, with an 11-28 cassette and 50/34 compact crankset, gives you seamless mechanical shifting and plenty of gears to tackle any climb. The SL 6 also comes with Bontrager Paradigm tubeless-ready rims and tough Bontrager R2 700x28mm tires, so you’ve got a solid set of wheels for when you want to test out that suspension system.

Ride Impressions Bringing the Domane SL 6 to a spring group ride feels a bit like cheating—the bike is so fast, smooth, and versatile that it can make you feel stronger than you actually deserve to feel after a long winter of Netflix -enabled sloth. I’ve test-ridden some of the higher-end Domanes in the past (up one of the hardest climbs I’ve ever experienced, Mount Figueroa, in Solvang, California) and had a similarly impressed response, but I reasoned some of my “wow” reaction had to have been tied to how far out of my price range that bike was. To my delight, the Domane SL 6 brings a lot of that same lightweight, road-smoothing magic and X factor to a more affordable price range.

Trek Domane SL6

From the moment I hit the first loose-gravel climb on one of my usual lunch routes, I was sold on the bike’s seamless Ultegra shifting and talent for soaking up road chatter with IsoSpeed suspension. Big bumps in the road still jarred me, but the washboard ruts didn’t throw off my handling or rattle my shoulders too much. The endurance geometry helped with that, too—long rides were as comfortable from beginning to start as you can expect, without any sacrifice in speed. And the Bontrager R2 28mm tires were great on both smooth asphalt and rough gravel.

Trek Emonda SL6 Pro review

Trek's latest GC/climbing bike has undergone an aero transformation, but has it helped?

  • Sign up to our newsletter Newsletter

trek emonda sl6 pro

The radical changes brought about in this new Emonda frame are somewhat hampered within the SL range owing to the heavier nature of the frame and subsequent ride quality of the 500 Series OCLV carbon. It is a solid all-round performer and there's no getting away from the fact the ride quality provides a good balance of efficiency and ride comfort. It's just if you were looking for an improvement on the ride of the previous model you'll need to hold off and get one of the higher level SLR models to truly see improvements.

Heavy for a 'climbing' bike

James Bracey

Trek recently released a brand new re-imagining of the Emonda, the brand's lightweight climbing/GC model platform, featuring a drastically aero-ised chasis. The model family is split into a higher tier SLR and the lower SL range that this SL6 Pro sits in, the critical difference is in the carbon layup and the enhanced integration sported by the SLR range.

The frame on the Emonda SL6 Pro is constructed of Trek's own 500 Series OCLV carbon fibre. This carbon layup might be heavier than the newly showcased ultra light 800 Series OCLV of the top level SLR Émonda's but is considerably more economical to produce, helping keep the SL range prices in a much more affordable tier.

>>> The Trek Madone gets an update, but you won't spot it

The new Emonda features a completely new set of tube shapes, most of which have gone down the aero route. But Trek is at pains to keep the comparisons to the Madone aero race bike to a minimum; this isn’t simple a ‘Madone Lite’. Rather than being the same elongated shapes as found on a proper aero race bike, the aero shaping of the Emonda’s tubes is much more subtle and is based around the principle of unsteady aerodynamics.

>>> Best road bikes reviewed

trek sl 6

In this case it’s more about how drag is affected through wind gusts and other factors at slower speeds than the usual 45km/h, after all, not even pros climb at these speeds. There are still the characteristic truncated airfoil shapes that we associate with aero frames but the effect is far less dramatic and produces a frame that still has a traditional look.

Trek Madone SLR9 Disc review

Trek hasn’t jumped on the dropped seatstay bandwagon with the new frame either, preferring to stick to a set of widely spaced yet aero shaped, thin seat stays.

trek sl 6

The new frame also enjoys a little more integration, bringing it more in-line with the Madone. All models now see the cable routing brought neatly into the frame at the front of the headtube keeping the front end profile as slippery as possible.

The other notable feature of the new frame is a wholesale move to the T47 bottom bracket standard . This style marries the reliability of a threaded shell with the capability of running larger diameter internal bearings and enables Trek to maintain its characteristic wide and efficient bottom bracket stance.

The new Emonda range has also been designed with Trek’s middle-ground H1.5 geometry ensuring a set of numbers that sits it half way between the ultra-aggressive pro H1 and its laid back and relaxed, endurance specific H2 geometry. A tall stack of split spacers under the stem provides plenty of height adjustment for a wide range of rider requirements.

trek sl 6

And finally, keeping the Emonda in a pretty rigid user set Trek has bucked another trend and limited tyre clearance to just 28c putting the focus of the bike purely on road going high performance.

The SL6 Pro sits near the top of the SL range and as such has a a pretty decent spec sheet. A mechanical Shimano Ultegra is the least we would expect at the +£3,000 price point and we don't need to point out how reliable and consistent it is in providing smooth shifting and braking.

As with the entire Emonda range the SL6 Pro runs on Bontrager wheels; Aeolus Elite 35 to be precise. These feature a carbon 35mm depth and complement the new 'aero' frame without compromising too much on weight and climbing ability. They feel stiff under power and spin up to speed relatively quickly. There are lighter and faster wheels that would suit the new frame but at this price point the Aeolus Elite is spot on. The tyres are Bontrager as well, in this instance 25mm R2 Hardcase Lite tyres. These are not Bontrager's fastest tyres, more classed as an everyday tyre with plenty of puncture protection.

trek sl 6

In a complete whitewash the entirety of the finishing kit is also provided by Bontrager. Unlike the integrated carbon bar/stem of the higher end SLR models, the SL6 Pro is fitted with a standard aluminium handlebar and separate stem, allowing for much simpler cockpit customisation. Despite the more ordinary setup the cable routing is still really neat underneath the stem without needing any additional housing.

The Émonda maintains the 'reversed' seat post, with a larger diameter seatpost mast fitted over the seat tube. This allows for plenty of adjustment plus further lengths are available if needed. The Bontrager Aeolus saddle also stands out for being incredibly comfortable even when sat right on the nose.

trek sl 6

I was curious to see if the new Emonda was able to improve on the ride quality of the highly rated existing version and the short answer is yes, well kind of....

The first thing to note is that in this new guise, the lower SL version I have on test feels a little chunky at over 8 kilograms - not something you expect when the bike's raison d'etre is all about low weight and climbing. However a total mass doesn't always equate to an anchor of a ride experience and this is true of the Émonda.

Trek has managed to provide a level of stiffness around the bottom bracket that enables the Émonda to deliver in its promise of rewarding effort. Granted it takes less effort to maintain speeds on flat and rolling terrain, much like the Madone aero bike, and I'm certain it is a 'faster' bike than the last version. But I can't help but feel that this new design has stifled some of the existing model's lively and exciting ride nature - it feels like using adjectives such as solid and dependable is more appropriate, almost like the Domane endurance bike.

trek sl 6

Trek's relaxing of the geometry on the Emonda has increased its ability to keep you comfortable and riding hard on a long ride and I had no issue taking on some challenging and long routes around Dorset and South Wales. The tall stack of shaped and split spacers sit the cockpit a little too high for my personal preference but luckily I was able to drop the stem height by using some standard spacers on top of the stem, without needing to cut the steerer. This put a little more weight on the front wheel which enabled me to descend the Émonda with aplomb and happily stuff it into downhill corners at high speed without any of the vague feeling that can come with a front end that is a touch too high.

Climbing is where the Emonda should thrive and it certainly is no slouch on your typical British climb, however it doesn't set the tarmac alight and the near eight kilo weight does neuter the Émonda's ability to counter attack when your riding mates try to accelerate away from you on a climb.

It feels like I'm being a little harsh and critical of the Emonda SL6 Pro, after all in most respects it is a solid all-rounder and I have enjoyed my time riding the bike over the last few months. It's a great looking bike and I expect most riders will be satisfied with the performance, it's just I feel it has a lost a little of the magic the old version had. If you are looking for the sort of engaging ride the Emonda is known for I suspect you would need to save your pennies and opt for one of the lighter SLR options and certainly if it was my money that would be what I would need to do.

2021 Trek Emonda SL Pro 6 road bike review: for the climb lovers

The first review from our 2021 road bike field test. we review and compare the mid-priced version of trek's newly overhauled emonda race bike..

Heading out the door? Read this article on the new Outside+ app available now on iOS devices for members! >","name":"in-content-cta","type":"link"}}'>Download the app .

When it was first released, the Emonda was a climber’s dream that Trek claimed as the world’s lightest production offering. Dealer events would have the ultra-premium 4.6 kg (10.25 lb) SLR 10 hanging from large helium balloons, and the American company made a big deal of it providing a benchmark stiffness-to-weight ratio. 

In many ways the Emonda back-filled the void left by the once round-tubed and low-weight Madone that was then becoming more aero. And as the Madone further trended to becoming Trek’s full aero racer (with an obvious element of comfort, too), the Emonda kept to its round tubes and stiff hill-attacking personality.  

That changed for 2021 with Trek overhauling the Emonda in a similar way to how almost every other brand has overhauled its lightweight race machine. The Emonda, now disc-only, gained a little weight by moving to slippery truncated airfoil tubes and a wholly new approach to cable routing in an effort to make it sleeker all-around. Additionally it should run quieter with a new threaded bottom bracket format, too. 

All of those techy details (and more) were covered in James Huang’s review of the top-tier Emonda SLR . And while James went pretty deep with that review, he left a few unanswered questions in relation to the more affordable 2021 Emonda SL. And so it’s exactly this more-affordable, second-tier version – specifically the Shimano Ultegra-equipped Emonda SL 6 Pro – that we took to our Field Test in Victoria’s High Country .

Emonda SLR vs Emonda SL

Story highlights.

What: A second-tier version of Trek’s all-round lightweight race bike. ||Key updates: Aero frame design, a more performance-oriented geometry, sleek semi-concealed cable routing, T47 threaded bottom bracket||Weight: 8.01 kg for the Emonda SL 6 Pro as tested (54 cm, without pedals), claimed frame weight is 1,142 g (56 cm).  ||Price: US$3,800 / AU$5,500 / £3,350 / €3,880-4,000||Highs: Obviously a race bike with geometry to match, agile handling, high-end looks, more tyre clearance than claimed, threaded bottom bracket, Shimano Ultegra is hard to fault, great saddle. ||Lows: Stiff ride quality, weight penalty in frame versus premium option, heavy carbon wheels, bend of handlebar is too tight.

There’s no denying that the Emonda SL (starting from US$2,700 / AU$4,000 / £2,275 / €2,580-2,600) is substantially cheaper than the pro-level SLR (starting from US$6,700 / AU$9,300 / £5,450 / €6,200), but what are you giving up in the process? Simply, it’s a matter of weight. 

An unpainted 56 cm Emonda SLR frame has a claimed weight of 698 g, while the matching fork adds 365 g. By comparison, the Emonda SL frame sits at 1,142 g, with the fork at 380 g. This 450-gram difference is simply attributed to the carbon composite layup used (in Trek marketing speak, that’s OCLV 800 vs OCLV 500), and simply less material is needed when the more expensive fibres and resins are stiffer and stronger.

That 1,142 g figure for the Emonda SL isn’t terribly heavy, but it is noticeably plumper than many other second-tier racing frames on the market. For example, the new Giant TCR Advanced frame offers a claimed weight of just 850 g, while Canyon’s comparable Ultimate CF SL frame has a figure of 980 g. And the Emonda SL’s higher frame weight is of course reflected in the complete bike weight, too, with our 54 cm SL 6 Pro tester tipping the scales at 8.01 kg (without pedals). 

Beyond the weight, the Emonda SL and SLR framesets are remarkably similar. They share the same moulds, and therefore the geometry and aero tube profiles are identical. Trek claims the stiffness profiles, and therefore ride quality is effectively equal. The way the cables are funnelled through the front of the head tube is the same, the new threaded T47 bottom bracket is mirrored, and likewise for the use of Trek’s reverser topper seatpost design. And heck, even the paint of our SL 6 Pro was an almost exact match to the SLR 9 that James tested. 

trek sl 6

Beyond the frame there are some more apparent differences. The SLR models feature a wonderfully light Bontrager one-piece carbon handlebar and stem, while the SL models use a more traditional bar and stem setup. And it’s a similar story for the other components which are lighter (and more expensive) on the SLR models. 

A race-ready geo and ride

The Emonda of old had two geometry options. There was the low and aggressive “H1” pro fit (offered in the SLR level only), and then the more mainstream “H2” with its more accessible and upright stack figure. For 2021 Trek combined those two fits into one with “H1.5” being used across all Emonda models.

That means the new Emonda SL is more aggressive than the last, and relatively speaking the reach figures are on the long side and the stack figures are fairly low. For example, our 54 cm tester offers reach and stack figures of 386 mm and 541 mm respectively, right in the realm of where many race-focused machines sit.

The handling is equally as sporty, with a traditional 73º head angle and 45 mm fork offset combining for a 58 mm trail figure with the control 28 mm Continental GP500 tyres fitted (25 mm Bontrager tyres are fitted as stock). And the wheelbase is kept fairly tight, too. 

Trek balances that longer reach by fitting a shorter-than-usual stem (90 mm on the 54 cm), and as a result the bike fits a little more upright than the figures may suggest. At the same time, that shorter stem produces a bike that handles even quicker and with less input than other race bikes with comparable trail figures. 

And it’s this quick-feeling attitude that will reward a rider with good handling skills. The Emonda can dive into turns and jump back out of them with little input. And it does that without an inkling of instability at speed.

Further rewarding a good handler is the stiff frame that pounces when called on and lets you feel what the tyres are doing through your hands and bum. No doubt, this was the firmest-riding bike we had at our small Field Test, and despite the wider 28 mm tyres, I could still feel the cracks and inconsistencies in the road surface. Thankfully that stiffness manages to find the right side of the line between a bike that speaks to you and one that skips about. 

Both Andy van Bergen and I agreed the Emonda was the most impressive under power when directly compared to the Giant TCR Advanced Pro and Canyon Ultimate CF SL , and similarly it beats the Specialized Tarmac SL6s that we both have sitting at our respective homes. I’d most liken the ride to BMC’s recently updated and stiffened Teammachine SLR01 .

That stiffness is great for riders who like out-of-the-saddle attacks and to feel their energy reach the rear wheel, but it’s less ideal for those seeking a smooth and compliant machine. And while many other brands utilise flexible seatposts to achieve more comfort through the saddle, Trek’s own reverse topper seatpost design just rides stiffer than the company claims and there are no options to change it for something more flexible – a somewhat surprising element given the company has gone to great lengths with its IsoSpeed technology to produce seated flex in its aero race and endurance platforms. 

Instead your best bet to add comfort to the Emonda is through the tyres. Trek officially states the Emonda can fit up to a 28 mm tyre, however that figure is extremely conservative. I trialled some 32 mm GP5000s (measured 32 mm width) in the frame without any sign of issue.

Compared to the previous version, living with the new Emonda frameset has some wins and losses. The new internal cable routing sees the brake hoses and shift cables enter through a funnel at the proprietary headset top cap, and then squeeze between the squared-off fork steerer and top headset bearing. It looks wonderfully clean, but as James previously covered, it does introduce some servicing difficulty, and that’s especially true for this model that uses mechanical shift cables.

Perhaps offsetting that servicing pain is the new T47 threaded bottom bracket , something that’s more universally compatible with oversized crankset spindles and surely simpler to service than Trek’s previous BB90 design that saw bearings pressed directly into the carbon frame. And while that new bottom bracket (made by Praxis) does require a unique tool, servicing it is vastly more accessible than with the former press-fit design.

I won’t get into the nitty-gritty of the aerodynamic design – we’ve done that – but I will say that the lines of this bike are quite stunning. The aero head tube is just so distinct, the wide and concave top tube offers a wonderfully interesting curvature, and similar can be said for where the long and flowing seat stays connect.  

The paint is also well done and makes this look far more expensive than it is. And as an added bonus there’s a second choice of colours, too (dark grey with chrome lettering). Although, perhaps Trek could have been a little more subtle with its logo, rather than turning the down tube into a rolling billboard. 

Carbon wheels aren’t always light

The tested Emonda SL 6 Pro sits smack bang in the middle of the Emonda’s range and features a full Shimano Ultegra R8020 mechanical groupset matched with a smorgasbord of Bontrager components (Trek’s own component and accessory brand).  

Below the SL 6 Pro (US$3,800 / AU$5,500 / £3,350) is the SL 6 (US$3,300 / AU$n/a / £2,900). The two bikes are effectively the same with the exception of the rolling stock. The cheaper SL 6 features Bontrager’s aluminium Paradigm Disc wheelset shod with the company’s R2 Hard-Case Lite tyres in a 28 mm size, whereas the tested Pro version moves to the carbon-rimmed Aeolus Elite 35 Disc wheels wrapped in a 25 mm version of the same tyre model. 

Adding US$500 to the bike’s price, those carbon rims offer a relatively shallow 35 mm aero-profiled rim that handles remarkably well without any sign of the flutter often present with deeper wheels in crosswinds. They offer a fairly modern profile, with an inner width of 19.2 mm and an outer width at 27.7 mm. However, the material is somewhat misleading and these wheels aren’t as light as you may expect. I weighed my sample set at 1,740 g for the pair (770 g front, 970 g rear).

trek sl 6

That weight doesn’t sound like much, but it impacted how the bike felt when attacking steep slopes, with Andy remarking that it made the bike feel sluggish to respond. Carbon isn’t always an upgrade. 

Another area that left Andy and I underwhelmed was the Bontrager Elite VR-C handlebar. We just didn’t get along with the ultra compact shape of the drops which left me complaining of wrist clearance issues, while Andy found that he was unable to make comfortable use of the drops due to his hand sitting proud within the tight radius. We both agreed that the handlebar would be the first thing we’d change.

Thankfully that’s the extent of our issues, and the rest of the build kit is hard to fault. Bontrager’s basic alloy stem works with its Blendr series of computer and light attachments (some of which are supplied), while the new Bontrager Aeolus Comp saddle features a modern short-nose design with a generous centre channel. And all the smaller details, including the proprietary headset top cap and seat post topper, add to a premium look and feel. 

trek sl 6

And finally there’s the Shimano Ultegra groupset. One thing James wasn’t able to test in his review of the SLR 9 was how the internal cable routing impacted mechanical shifting quality. I can confirm that it doesn’t. The shifts were just as snappy and consistent on this bike as they were on other bikes, and they should remain that way for a fair while with full-length housing used from shifter to derailleur. And that full-length housing should ease future repairs, although it does add to the bike’s total weight. 

Champagne tastes on a (craft) beer budget

Despite the lower price, Trek has done a solid job of bringing the Emonda SLR’s attributes to the SL. It offers the same handling, stiffness and aesthetic of its pro-level sibling, and that makes for an impressively enjoyable bike to ride.

However where the more expensive Emonda jumps with joy at every thought of an attack, the extra mass of the SL sees it hesistate somewhat. That difference may not be reflected on the clock, but it sure can be felt and it’s a constant reminder of the price tag attached to this ride. 

The new Emonda SL will be a good fit for the rider wanting a well-rounded race bike that handles and behaves like a WorldTour machine. However it’s best to avoid this one if you’re seeking an opulent ride quality or the lightest bike for the given sticker price.

Trek Checkpoint SL 6 AXS review – all-round gravel machine

Trek’s checkpoint has unique progressive geometry and scissor frame features and all the mount points you could want. but is it a multi-surface, multi-mission master or a complicated compromise.

Trek Checkpoint SL6 artfully parked by a river

BikePerfect Verdict

Genuinely ride improving IsoPulse frame tech with unique handling that’s happy from road rides to rough bikepacking, plus tons of mount points and a sweet spot spec list make the Checkpoint SL 6 an excellent, easy yet efficient choice for whatever you want gravel to be.

IsoPulse Decoupler is a significant ride smoother

Well balanced road or rough handling

Efficient speed on all surfaces

SL 6 model is a real performance for price sweet spot

Saddle is a bit squishy on longer rides

Many mounts mean slightly more mass

Controls go through the headset

Non removable front mech tab

Rough rear hub

Why trust BikePerfect Our cycling experts have decades of testing experience. We'll always share our unbiased opinions on bikes and gear. Find out more about how we test.

Trek’s second generation Checkpoint gravel bike has a unique, ride smoothing scissor frame design, confidently controlled handling, internal storage plus lots of clever external cargo fittings including custom bags. The SL 6 looks like a sweet spot in terms of performance for price too. I have been getting the multi-surface miles in to see how the Checkpoint checks out as an all-round race and adventure candidate. 

Trek Checkpoint SL6 storage hatch

Design and geometry

The first impression of the Checkpoint SL is what a chunky frame it is. The massive downtube leaves plenty of storage space under the latched hatch though and together with the broad seat tube means full width support of the oversized T47 bottom bracket. The broad rectangular top tube gives plenty of real estate for bolt on bags above and below it. It also hugs round the head tube to create a deep brow below the upper segment that turns with the bars and acts as entry point to the internal control routing. The deeply dropped asymmetric stays are chunky too and even the seat stays are sturdy pieces by modern ‘flexy and friendly’ standards.

Normally this would read like a classic recipe for a horribly rigid ride, but hiding under the pop out servicing panels at the tope tube/seat stay/seat tube junction is a skewering pivot axle. This ‘IsoSpeed Decoupler’ lets the seat tube flex back and forth above and below (where the tube is dramatically scooped out) the axis of the pivot for an impressively smooth ride in the saddle but a very stiff feel underfoot. Specific variations of the theme have been used successfully right across Trek’s road, CX, MTB and gravel ranges for a while too.

Trek Isospeed Decoupler 'suspension' detail

As well as the internal space and top tube mounts, there are four bottle cage positions, hidden fender mounts, less hidden frame mounts and the mandatory triple holes down each carbon fork leg for whatever you want to bolt/strap on. There’s a steel scuff plate behind the chainring (maximum size 46T) plastic armor on the belly and an adjustable chain keeper. There’s ample space for 700 x 45mm or 650 x 52mm (27.5 x 2.1in) tires in frame and fork too. The only glitch is the redundant but irremovable front mech mount sticking awkwardly out from the seat tube.

OCLV 500 is Trek’s mid price, mid weight carbon composite option with a claimed 56cm painted frame weight of 1480g and a fork weight of 501g. This makes it heavier than the Checkpoint SLR chassis, but that’s not available separately, while the SL is $2,399 / £2,500 / €2,699

Components and build

As the model name suggests, the SL6 gets SRAM’s AXS wireless gear set up. It’s the lower/mid tier Rival group with an alloy crank (the SL7 AXS gets Force and carbon wheels) with a 40T chainring matched to a 10-44 tooth XPLR cassette. The bottom bracket is the latest T47 standard. Shifters and hydraulic disc brakes are Rival too, with 160mm rotors for decent stopping power.

Bontrager Paradigm Comp wheels use alloy 25mm wide rims with hard plastic tubeless sealing strips for long term durability. Stock bikes come with Bontrager GR1 Team Issue tires but my sample bike was running Pirelli Cinturato Gravel M Classic tires in the same 40mm width. The Bontrager Switch thru-axle has a removable lever with 4 and 5mm Allen keys in the tip too. The non-adjustable rear hub bearings were sounding super rough and wobbling within a few days of riding though.

Bontrager supply all the finishing kit including a carbon seat post and a particularly squishy saddle. All the contact points are size specific with different crank lengths from 165mm to 175mm, 38 - 46cm bars and 70 - 100mm stems depending on frame size. You get a wider saddle on 49 and 52cm bikes as well.

Complete bike weight of our 56cm test bike with bottle cages and internal storage sleeves but no pedals was 9.3kg. The price compares well to other carbon gravel bikes with internal storage like the Specialized Diverge and Santa Cruz Stigmata too although It’s worth noting that the same bike (identical apart from a moss green finish) has just appeared on the Trek UK website for only £4,300 and I imagine other territories will update soon.

Ride, handling and performance

There’s two main things to talk about with the Checkpoint that are unique to this bike – the IsoSpeed Decoupler and the ‘progressive’ handling. It’s certainly not unique in saying it has ‘progressive’ handling but Trek do it different. Rather than slackening the head angle in an MTB style, they’ve kept it road bike steep (72.2 degrees on my 56cm test bike) but reduced the rake (angle between a vertical line through the centre of the hub/tire contact patch versus the hub and steering centers – aka headset – of the frame) of the fork. In one sense this makes it more responsive through the bars and Trek have amplified that by using a shorter stem than normal. However, the smaller rake means a longer trail figure (distance between that vertical line through the hub centre/tire contact patch). That means the front wheel ‘castors’ more strongly so it wants to stay straight and the bike needs more effort to get it to change direction. Trek have also lengthened the reach by 20mm on average and added 10mm to the rear centre so you’re getting significantly more stability that way too.

Overall then you’re getting a more resolute, ‘I’ll keep going straight rather than freaking out and tripping up’ character than average on the Checkpoint through rough, rooty or loose rock situations – while still having a light and sensitive steering feel. Its definitely subtly different to something like the Santa Cruz Stigmata where the head angle has been slackened dramatically MTB style. That manifests in a keener, more reactive feel through the bars on Checkpoint on climbs and in slow speed situations. That’s emphasised by an already slack seat angle that gets even slacker as the seat post bows backwards under high torque / low revs effort so you’re balancing between alert accuracy and popping the front wheel up and losing control at extremes. It’s not quite as planted through fast, drifting turns as the Stigmata (my current ‘gravel speedway’ benchmark) as you can provoke it to twitch and tweak at the limit. It feels less sluggish and barge like on the road than a slacked out bike though. The deeper than average (for gravel at least) drop on the bars and fast rolling tires also gives a more ‘all-road’ vibe. So if you’re likely to run fast tires or even invest in a separate set of road wheels rather than fit a dropper post and knobbly rubber, then the Checkpoint is a really effective and enjoyable balance.

That’s not to say it’s not very smooth and capable on rougher terrain though because the IsoSpeed tech really does work well. Not as obviously as a suspension seatpost, but in a more organic ‘smoothes the sharp edges and slap sting off roots and rocks’ sense that feels a lot like running much bigger tires than you are in terms of both comfort and traction. Fore and aft flux means it can feel a little ‘rounded off’ when pedaling hard in the saddle, but stand up and there’s clearly a very solid and purposeful drive delivery to the back wheel. The back wheel still carves and cuts cleanly rather than writhing across it’s axis if you’re pushing hard through turns or off cambers too.

While Trek have abandoned their front end IsoSpeed tech, the fork is similarly smooth and forgiving without slurring tracking so there’s no ‘game of two halves’ mismatch to unsettle the handling. The Bontrager Elite Gravel bars have rubber padding embedded in their top surface for a bit of extra comfort and the squidgy saddle plays it’s part in isolating the trail. The fact it’s still an active tracking and laterally stiff bike is obvious and welcome when you’re tackling singletrack or sketchy descents while loaded up for a few days of bikepacking. Even a full size seatpack rammed with a tent, stove and a couple of campsite tinnies didn’t set up any weird harmonics or wriggle at speed and knowing the top tube bags are physically bolted into place adds mental and mechanical confidence too.

The 160mm brake rotors both ends and 44 tooth largest cog on the XPLR cassette are welcome when loaded too and as usual the Rival AXS set up was totally trouble free through an extensive test period. Apart from the premature death of the bearings in the rear hub the Bontrager wheels seem tough, but a lighter set would definitely pep up the dutiful rather than dynamic accelerating character of the SL 6.

Bontrager saddle on Trek Checkpoint

Trek like doing things differently and there’s definitely a lot of distinctive features to the Checkpoint. The result never feels weird though, just a great balance of smoothness, assured but not dull handling and efficient yet comfortable speed across a wide range of surfaces. It’s ready to have pretty much any accessory from dedicated bags to commuting fenders bolted on too.

While you can go lighter with the SLR frames, fancier with the various pricier SL models, or cheaper with the alloy ALR models, the SL 6 is a definite sweet spot pick. It's full of wireless functionality, carbon frame and proportionately sized componentry without paying any more than you need to. And if you can invest later it’s definitely a frame worth upgrading not least because it’s blend of 'feels good on the road' and when loaded up for wilderness bikepacking (as well as everything in between) makes it very versatile.

I tested Cervelo’s new Aspero gravel bike. It still definitely hauls ass, but doesn’t kick it as much in the process

Is Rotor's Kapic crankset and oval Q Ring setup pedaling perfection, or did it leave me riding all out of shape?

Trek Checkpoint SL 6 eTap review

Can this Checkpoint compete with pricier and racier models?

Russell Burton / Our Media

Notably comfortable ride; very versatile

Inelegant seat-clamp design; occasionally rattly

The Trek Checkpoint is one of the most versatile gravel bikes out there from a mainstream brand.

It bristles with mounts for all sorts of things – triple-boss bikepacking bags , mudguards , extra bottle cages, pannier racks and top-tube bento boxes are all invited to the accessory party.

This versatility, paired with the comfortable ride provided by plush tyres and Trek's compliance-boosting IsoSpeed technology, makes for a sensible option that will work well for many riders.

Trek Checkpoint SL 6 specs

The Checkpoint SL 6 sits in the middle of the new 2022 Trek Checkpoint SL range , updated with a refreshed geometry, clearance for 45mm tyres (on 700c wheels, or 2.1in tyres on 650b wheels) and the aforementioned mounting points.

The SL is the second-tier frame, made from Trek's 500 Series OCLV carbon fibre. The top-tier SLR frame gets upscale 700 Series OCLV carbon for reduced weight, plus a seatmast with integrated IsoSpeed decoupler, compared to the SL's conventional seatpost and seat tube-located IsoSpeed.

At 9.47kg for my size 56cm bike, the mid-range Checkpoint SL 6 is no heavyweight, though that definitely doesn't make it the lightest gravel bike out there.

However, when you consider it's built up with SRAM's rather weighty Rival AXS XPLR groupset in a 1x guise and chunky alloy gravel wheels , you’re not giving up much in terms of frame weight for a package that's more versatile than many of its contemporaries.

The finishing kit is all from in-house brand Bontrager, including the GR1 tyres.

For a little more, the Checkpoint SL 7 gets a SRAM Force groupset and Bontrager Aeolus wheels. Both upgrades together only drop a claimed 420g, but the 2x drivetrain will make this a better choice for most road riding.

If you can forgo electronic shifting, the Checkpoint's SL 5’s Shimano GRX components won’t leave you wanting. The rims are slightly narrower (21mm), but this will only matter if you run very wide tyres.

Trek Checkpoint SL 6 ride impressions

The key feature of the Checkpoint family is Trek’s IsoSpeed decoupler system. On the Checkpoint SL, this splits the seat tube from the top tube, allowing it to flex around a pivot. This system helps take the sting out of bumps, particularly when seated. It's hard to quantify but, psychologically at least, the system helps reduce fatigue on rough climbs.

Trek dropped front IsoSpeed for this generation of the Checkpoint. Nonetheless, despite the fork’s chunky blades and very broad crown, square-edged hits to the front wheel aren't overly harsh.

The plump 700x40c Bontrager GR1 tyres mounted to the 25mm wide (internal) Bontrager Paradigm Comp wheelset also contribute as much to the comfortable ride as any carbon wizardry.

The tread consists of nine rows of tightly packed knobs that get larger towards the shoulder.

Like all tyres of this ilk, they don’t shed claggy mud very well, but have plenty of grip on drier surfaces when run at lower pressures. They also feel pretty good on the road.

Clearances for up to 2.1in tyres on 650b wheels or 45mm on 700c mean you can tackle wilder terrain.

The pliant ride and geometry make for a confident, fun and calm partner on singletrack trails and for high-speed riding.

It’s definitely not a gravel bike that errs into pseudo mountain bike territory, but it's one of the better-behaved gravel bikes I've tested on gnarly trails.

A swap to gravel tyres with a more aggressive tread would also greatly improve control in rough terrain if that’s a key performance factor for you.

The Bontrager Elite Gravel is one of the best gravel bike handlebars I have used – in my mind, it really is close to perfection. It has long drops that give ample space for your hands to move around without squashing them up into the hooks. The 75mm reach is also generous enough to allow your hands to move fore and aft when riding on the tops.

At 42cm wide on the size 54 and 56cm bikes, it's not excessively wide either. The squishy Bontrager P3 Verse Comp saddle will also be a crowd-pleaser.

The Checkpoint is slightly noisier over rough ground than other gravel bikes I have tested.

The cable-routing system forces the cables to run close to the underside of the stem so, off road, the cables rattle against the stem.

It’s also a shame that the external seat clamp (hooray!) sits above a rather ungainly step from the wider-diameter tube down to the clamping surface. Functionally, it’s fine and it’s a small detail, but it detracts visually from the otherwise premium-looking frameset.

The Checkpoint SL 6 presents decent value for money, with a well-thought-out build and a frameset that's notably versatile without looking too ungainly.

As has been proven before, IsoSpeed really does work as advertised.

That comfortable ride – in combination with the ability to run an array of accessories and carry enough water to quench the thirst of a flannel-wearing gravel army – sets the Checkpoint apart as a sensible option for bikepacking, adventurous riding and those interested in traditional long-distance gravel racing .

How we tested

We set out to test three of the latest gravel race bikes – a fast-developing sub-genre of machines aimed at covered varied ground quickly.

The Trek Checkpoint has been redesigned for 2022 as a versatile gravel bike capable of turning its hand to racing or multi-day riding.

The Specialized S-Works Crux, meanwhile, has been reimagined as a super-light gravel machine aimed at go-fast riding.

Finally, the Wilier Rave SLR arrives as the Italian firm's take on gravel, with road and off-road builds available.

Our testing involved skittering over the hardpacked Fosse Way in the Cotswolds, cruisy loops on local roads and getting bogged down in the mire of claggy mid-winter byways.

Trek Domane SL 6 Review: Top-Quality Parts and Endurance Performance

domane sl6 frame

Trek Domane SL 6 Gen 4 is Trek’s second-highest bike in the carbon SL range and it spares no expense on top-quality parts and manufacture.

From here on up is the Domane SLR range, bikes that are focused on team-sponsored events and are mostly unaffordable to individual riders.

At its core, the SL 6 boasts Trek’s groundbreaking IsoSpeed shock reduction system built into its patented 500 Series OCLV carbon frame.

Together, the two offer one of the best carbon road bike framesets available, providing rigid stability and exceptional comfort.

Trek Domane SL 6 Quick Overview

Main features, is the trek domane sl 6 right choice for you, is it worth the money.

Trek Domane SL 6 Gen 4

With a Shimano 105 groupset, internal Di2 routing, Paradigm Comp rims, and a carbon seat post, it’s clear to see that Trek spared no expense when building the Domane SL6.

  • Frame : 500 Series OCLV Carbon, front and rear IsoSpeed, DuoTrap S compatible
  • Fork : Domane SLR carbon, internal brake routing, fender mounts
  • Front Derailleur : Shimano 105 R7150 Di2
  • Rear Derailleur : Shimano R7150 Di2
  • Wheels : Bontrager Paradigm Comp 25, tubeless-ready
  • Number of Gears : 22
  • Brakes : Shimano SM-RT70
  • Tires : Bontrager R3 Hard-Case Lite, aramid bead, 700x32c
  • Weight : 19.63 lbs / 8.90 kg

Get From TREK

The Domane SL 6 features quality parts from top to bottom, starting with the IsoSpeed frame and working down to the 105 groupset and Paradigm rims.

It’s a bicycle that personifies speed, comfort, and efficiency in every way possible.

Shimano 105 groupset

Shimano 150 groupset

Domane SL 6 used to sport a Shimano Ultegra groupset, but this year they’ve switched it back to 105.

While it might seem like a downgrade, 105 is one of the most popular groupsets among road cyclists and amateur racers.

OCLV carbon IsoSpeed frame

Trek has spent years developing its IsoSpeed system and it’s come through several iterations to reach the current product.

Designed as a means to absorb road shock without sacrificing efficiency, IsoSpeed is a somewhat futuristic frame technology.

It works by decoupling the seat tube from the frame using a rocker cup that permits some flex while maintaining rigidity.

While it might sound like overkill, it works so well you’ll likely never want to ride another bike without it.

This has been combined with its highly compacted, low-void carbon frame to add strength and confidence on even the roughest terrain.

If you’ve ever come off of a long ride feeling like your flesh has shaken off your bones, you’ll appreciate IsoSpeed technology.

It is particularly welcome on the famous cobbled streets that any European rider will be very well familiar with.

Paradigm Comp wheels

Trek Domane SL 6 comes fitted with Bontrager Paradigm Comp 25 TLR Disc road wheels with a Shimano 11-speed freehub on the rear.

The tubeless-ready rims have a 25mm inner width designed for wide road or gravel tires.

The SL 6 also comes with uncommonly large tires, in this case, Bontrager R2 Hard-Case aramid-bead 700x32c tires.

It’s an odd feature for a road bike but the extra fork clearance can actually take tires up to 38c in size.

Endurance geometry

Domane SL 6 Gen 4 is made for endurance riding

The geometry on Trek’s Domane SL range of bikes is designed to balance speed with comfort. It utilizes a slightly higher head tube to put the rider in a less aggressive position.

This provides better stability and comfort while maintaining a high degree of performance.

This helps the rider to conserve energy over long distances so there is still some juice in the tank for the final home stretch.

Micro-adjust seatmast

Amongst the Domane SL 6’s multitude of features is the micro-adjustable carbon seatmast.

It’s lightweight, aerodynamic, and provides millimeter-perfect adjustments for the exact right fit.

Professional riders will know the difference that even a millimeter in seat height can have on performance.

With the micro-adjust seatmast, you’ll be able to shave those much-needed seconds off your record time.

The Trek Domane SL 6 comes in 9 different sizes to fit heights of 4’11” to 6’5″.

  • 44 : 4’11” – 5’0″
  • 47 : 5’0″ – 5’2″
  • 50 : 5’2″ – 5’4″
  • 52 : 5’4″ – 5’6″
  • 54 : 5’6″ – 5’9″
  • 56 : 5’9″ – 5’11”
  • 58 : 5’11” – 6’1″
  • 60 : 6’1″ – 6’3″
  • 62 : 6’3″ – 6’5″

Trek Domane SL 6 is a professional carbon road for riders who compete regularly in races, sportives, and cycling events.

As the price indicates, it is not designed for casual use. The true potential would not be fully realized by an amateur rider.

However, the Trek Domane range does serve something of a niche in the carbon road bike world.

Rather than focusing purely on speed, Domane bikes are best suited to riders who will be tackling a variety of different terrain.

If you often find yourself held back by cobblestones, gravel, or dirt track, then the Domane SL 6 could be the answer you’re looking for.

It’s specifically designed to tackle undesirable terrain with smooth and calculated efficiency.

However, if purchased for the right reasons and used for its intended purpose, the Domane SL 6 will certainly make the buyer feel they have got their money’s worth.

The strong and build and quality parts mean the bike will last for years without the need for any expensive repairs or upgrades.

It represents the type of investment that may cost a lot initially but pays off in the long run.

2 thoughts on “ trek domane sl 6 review: top-quality parts and endurance performance ”.

I’m wondering about a point that was made in your review. You state that the IsoSpeed decouples the steerer tube and seat tube from the frame, but the Generation 4 Domane under review only has a rear IsoSpeed decoupler. (You can see this if you follow your link to the Trek web site for the bike under review.) The last Domane that had both front and rear IsoSpeed was Generation 3, which was discontinued in 2022.

Hi Steve! You’re right, thank you for pointing that out. It was an honest mistake that has now been corrected.

    By comparison, the Emonda SL frame sits at 1,142 g, with the fork at 380 g. This 450-gram difference is simply attributed to the carbon composite layup used (in Trek marketing speak, that's OCLV 800 vs OCLV 500), and simply less material is needed when the more expensive fibres and resins are stiffer and stronger.
