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

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.

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.

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.

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.

The headline news with the new Domane SLR is a two-pronged approach aimed at delivering front end compliance that bettmmer matches the rear IsoSpeed decoupler, a novel development in the original bike that provides a range of comfort-boosting deflection. A common complaint with the original Domane centred around the front end feeling much stiffer than the compliant rear end.

To solve this, Trek has integrated an IsoSpeed decoupler into the head tube, allowing a specially shaped carbon fibre steerer tube to bend slightly between the two headset bearings. We're only talking a very small amount of deflection, with rider weight and stem length being a factor in the bending range. Trek has also developed the new IsoCore handlebar. Within the carbon fibre layup is a layer of rubber that allows the handlebar to dissipate some of the high-frequency vibrations.

This combination works well, providing much improved – and needed – front end compliance. The bike feels much more balanced and forgiving at the front when tackling cobbles or badly surfaced roads.

The other big news is the new adjustable rear IsoSpeed decoupler, which now employs a split seat tube design, first seen on the Madone aero road bike. On the old Domane, the entire seat tube was independent of the top tube, with its movement controlled by the IsoSpeed decoupler. In the new design, the front section of the split tube is attached at the top tube like a regular seat tube, which creates a stiffer frame, with only the rear section independent. The amount of deflection is also adjustable – loosen a single bolt (which shares duty as a bottle cage bolt) and slide the dividing lever into the desired position, with the lowest setting offering a claimed 14 per cent increase in compliance over the previous Domane, while in its firmest setting it mimics the Emonda.

But it's not all about twice the number of IsoSpeed decouplers and a rubber-infused carbon handlebar. Trek has increased tyre clearance so that the new bike now ships with 28mm tyres, and there's probably space for slightly wider tyres. Unfortunately, the supplied Bontrager tyres aren't tubeless, unlike the Bontrager wheels, but the tyres inflated to 65psi provide a huge cushioning effect with plenty of traction in the dry and wet, and are robust enough to deal with cobbles.

Ride and performance: The cobble factor

Trek launched the new Domane SLR in Kortrijk, Belgium, the day after the Tour of Flanders, and provided the assembled press with an opportunity to ride the bike over the same roads and cobbles used in that race. The Oude Kwaremont, Paterberg and Koppenberg provided an ideal circuit to put the new bike through its paces. I was rather spoilt in riding a Race Shop Limited (RSL) version with Pro Endurance Geometry (which you can buy through Trek's Project One custom bike programme), with the defining feature being the short head tube, and a smattering of top-end Shimano Dura-Ace and Bontrager Aeolus carbon fibre wheels, which all helped to provide a good impression. Regardless of the flash kit, it was clear on the cobbled sectors that Trek had succeeded in producing a bike that provides a smoother ride.

Following that launch, I was sent this Domane SLR 6, the base model in the range, equipped with Ultegra components and aluminium Bontrager wheels for review. A key difference with this bike is the H2 geometry, which basically means it has a taller head tube than the RSL bike I rode at the launch. It does make it more suitable for the vast majority of people looking to buy a Domane SLR, especially if you lack the flexibility that comes from spending 50-80 hours a week hunched over a keyboard.

Where better to test the new bike than the Paris-Roubaix Challenge? The 175km route takes in all 52 cobbled sections used by the professionals in the race the following day, and provides a tough challenge for any bike. After the first few cobbled sections had disappeared under the tyres, it was clear the work that Trek had put into this new bike had paid off; it showed a marked improvement over the previous model in terms of outright smoothness and comfort and a more rounded ride quality everywhere else.

The new Domane SLR feels stable and composed when rattling along the crown of a cobbled road, the vibrations less intrusive. The ride is just calmer. Bigger impacts, such as those on the Arenberg, can still send a jolt through the handlebar – there's a limit to how much the small range of deflection can really cope with bigger impacts – but it is on high-frequency vibrations caused by cracks in the road, ridges, depressions and smoother cobbles that the IsoSpeed decouplers, bigger tyres and carbon handlebar really make an appreciable difference and the Domane SLR excels.

I actually rode this same event a number of years ago on the previous Domane, and it's clear comparing the new bike with the old one that the changes have netted a substantial difference. Most noticeable is how much smoother the front end is, with better cohesion between the front and rear stiffness. The front is still firm, but the difference has been massively reduced and the result is a much more balanced feeling bike.

I've done Paris-Roubaix a few times and ridden the cobbles on quite a few different bikes, but I've never felt quite as fresh as I have after riding the new Domane SLR. Sure, I was still battered and I swore never to do it again, but I was in a better state than those around me. The measure of deflection might be small, but it's enough to make the going that little bit easier over such rough roads.

On familiar roads...

While the cobbles are a tough test for any bike, a truer test of the bike is revealed on local roads. No cobbles but plenty of poorly surfaced roads, the top layer of tarmac peeled away, surface dressed gravel and plenty of holes to contend with. It's on this sort of road that the Domane SLR comes into its own. It damps the vibrations and manages to isolate you just enough from the most severe bumps and dips, providing a floaty feeling without completely detaching you from what is happening under the tyres.

It's really quite wonderful how the bike smooths out a rough road, a feeling highlighted when I switch back to a carbon race bike with narrower tyres. Yet the Domane SLR doesn't feel baggy or loose, it's still direct and responsive if you like to ride hard and expect the bike to deliver the sort of performance that a race-bred carbon bike should. There's no flex when you sprint out of the saddle and it's direct and sensitive to small changes of weight balance or rider input.

It's uncanny how well the IsoSpeed works. Look down between your legs and, in the softest setting, you can see the seatpost moving back and forth. You don't notice the saddle movement when you're riding, you just notice the smoothness. I've experimented with the rear IsoSpeed decoupler in different positions. In its firmest setting, it's in the same ballpark as the Madone, and the ride feels crisp and alert. In its lowest setting, it sweeps rough roads aside, while the middle setting is equivalent to the previous Domane.

You can easily leave the slider at its lowest setting and make the most of the available deflection because it's sufficiently well controlled that it doesn't spoil the ride if you're enjoying some buttery smooth tarmac. It's not exactly bouncing up and down. The adjustability means you can alter the available deflection to suit the demands of your local roads and also your weight as well.

It's not all about the comfort...

Comfort aside, the Domane SLR is a really engaging and fun bike to ride. The boosted compliance hasn't softened the Domane's reflexes. It's a nimble bike, with the 7.6kg weight ensuring it can dance up the climbs with the best of them. In RSL guise, it would certainly be a good UK race bike.

The new split seat tube design provides a stiffer frame and it feels it when riding. Any concerns that the front end might be soft and vague vanish as soon as you get out the saddle and give it the beans, or climb aggressively up a very steep hill. It's solid and there's no unwanted flex. You can occasionally detect a hint of flex from the handlebar when in the drops but it's not detrimental to the performance of the bike.

While the rear IsoSpeed only works when you're seated, the front IsoSpeed decoupler and IsoCore handlebar make a noticeable difference all of the time, even if you're out of the saddle. Round my way there are some quite fast descents with really bumpy surfaces, the sort you might ride out of the saddle, and one in particular that is just horrible, with a rippled surface, holes everywhere, poor visibility due to steep banks and bends in the road, and a tricky right hander at the bottom. On a very stiff race bike, the ride can be choppy and bouncy as the tyres struggle to follow the surface of the road – it never feels very safe at speed. The Domane SLR, in contrast, feels controlled, safe and tied to the road, and much safer.

Equipment and pricing

There are five models in the Domane SLR range: two disc and three rim brake versions, plus two framesets if you want to build your own. This Domane SLR 6 is the least expensive in the lineup, and for your £3,600 you get most of a Shimano Ultegra groupset with a compact chainset and 11-28 cassette, with Bontrager Speed Stop direct mount brakes.

There's a strong Bontrager theme, as you'd expect, from the IsoCore handlebar to Bontrager Paradigm Comp tubeless-ready wheels. It's a real shame the Bontrager R3 Hard-Case Lite tyres aren't tubeless. I found the Bontrager Pro stem too short so swapped it for a 13cm stem to achieve my desired fit, likewise the Affinity Elite saddle, which I swapped for a Prologo Scratch.

The same frame is used throughout the range and is constructed from 600 Series OCLV carbon fibre with a host of familiar Trek features including a BB90 bottom bracket, internal cable routing and tapered head tube. Trek's Ride Tuned seat mast slips over the top of the extended seat tube and required a generous amount of carbon paste to prevent it slipping.

To provide the necessary tyre clearance, Trek has adopted the direct mount brake standard first introduced by Shimano, and this bike is fitted with Bontrager's own brake callipers. They're not pretty but they are effective, and while power isn't a match for a Dura-Ace dual-pivot brake, lever feel is nice and consistent.

The frame is DuoTrap S compatible, which allows a sensor to be plugged into the chainstay to transmit, via ANT+ or Bluetooth, speed and cadence data to a suitable computer or smartphone app. An integrated chain catcher is a neat addition, as is the new 'Control Centre', a hole in the down tube covered by a removable cover that is used to hide the junction box if the bike is fitted with Di2.

Like the original Domane, there are mudguard eyelets, making it an ideal candidate for winter riding.

> Check out our buyer's guide to sportive and endurance bikes

As mentioned previously, the Domane tested here uses Trek's H2 geometry, which basically means it's more relaxed and less aggressive than the geometry used by Fabian Cancellara and normal on typical race bikes. If you've read this far, you're probably more interested in the Domane not for racing but for sportives and club runs and leisurely Sunday rides, and don't want to have to fit yourself to a low and stretched race bike.

To put that into context, here are some numbers for the 56cm bike pictured. It has a 374mm reach and 575mm stack (the horizontal and vertical measurements from the centre of the bottom bracket to the top of the head tube) and a 175mm head tube and a 554mm top tube. Those numbers show that the front is higher and the reach to the handlebar shorter, which means a more comfortable riding position if you're not racing and like to enjoy, not suffer, on your rides.

Endurance bikes usually have a longer wheelbase, to provide extra tyre clearance and provide more ride stability, and at 1010mm the Domane has its wheels stretched out compared with a race bike. Seven frame sizes are available from 50 to 62cm.

The endurance bike category has some interesting contenders, and Trek's solution to providing a bike that deals with the poor state of the roads might seem gimmicky, but it does work – and works well.

The Domane just got even better. It's smoother and more comfortable than the original, and fast and fun as well

Trek Domane SLR 6 Disc road bike – review

Next generation endurance bike for riders who want to log big miles in supreme comfort.

The Trek Domane SLR 6 Disc is festooned with technology that will provide a smooth ride on any surface you’ll want to ride it on – without losing its ability to get a move on.

Launched during the 2016 Classics season, the latest evolution of Trek’s endurance bike was meant to give Fabian Cancellara a winning farewell to the races which have made Spartacus a great in the world of cycling.  With the exception of the Strade Bianche, it didn’t quite provide the fairytale ending, with Cancellara finishing second behind Peter Sagan at the Tour of Flanders.

But the Domane SLR is more than a Classics bike – it’s leading the charge for the next generation of endurance bikes for everyday riders who want to ride big miles in supreme comfort.  We’ve had our hands on a disc version of the Domane SLR to see if all the tech we discovered at the launch this spring really lives up to the hype.

The frame – comfort is king

Here we’ve got an SLR 6 Disc, built from Trek’s high-end 600 Series OCLV carbon fibre and all the innovative IsoSpeed technology Trek introduced earlier in the year, and teamed with the Domane’s swooping fork.

The Domane SLR Disc is based around Trek’s relaxed Endurance geometry, to provide a more upright position and predictable handling, as opposed to the aggressive position and razor-sharp handling of a race bike. Still, you can get the Pro Endurance geometry used by the team if you go through Trek’s Project One custom program – but that more aggressive fit is only an option on the rim brake frame.

Back to the Domane SLR Disc, and added into the frame is built-in support for Bontrager Duotrap speed and cadence sensors within the left hand chainstay, as well as internal cable routing throughout. The only exception comes in the front fork, which tightly binds the front brake cable to the inside of the fork, externally. While not creating the neatest and cleanest of front ends, it does make servicing that little bit easier – ideal if you plan to use your Domane over muddy cobbles, for example.

Specification

• Price: £4,000
• Weight: 8.3kg (56cm)
• Sizes: 48, 50, 52, 54, 56, 58, 60cm
• Website: Trek

Let’s just recap on some the headline features of the Domane SLR frame. The Domane was first launched in 2012 with the innovative IsoSpeed decoupler, which isolates the seattube from the toptube via a pivot and allows it to flex independently to improve comfort – now Trek have upped the ante on the Domane SLR by making that level of compliance adjustable via a slider on the seattube. It can be adjusted by slackening one of the bottle cage bolts and moving the slider, before tightening the bolt back up again.

Secondly, Trek developed a front IsoSpeed for the Domane SLR which places a second decoupler within the headtube, with the aim of softening the front end, and providing a more balanced ride at the front and rear.

With all that the Domane SLR represents something of a tour de force in the endurance bike market, so we took it out on UK roads to see just how effective that innovation really is.

The ride – quick, compliant and relaxed

Fundamentally, the Domane SLR’s behaviour is dictated by the geometry and IsoSpeed. In this Endurance geometry, with slighter higher stack and shorter reach than the Endurance Pro, it’s a bike which feels like it sits beneath you with complete composure, while the slightly more ‘sat-up’ position is naturally easier on your back and arms (and inevitably less aero).

Of course, an endurance geometry is all well and good, but that in itself doesn’t necessarily lead to a comfortable ride – the frame itself can be just as raw and harsh as any super-stiff race chassis. Enter into the fray, IsoSpeed.

While Trek have introduced front IsoSpeed to the Domane SLR, the adjustable, rear IsoSpeed decoupler remains the centrepoint of the frame – and it’s a wonder for riders wanting maximum dampening through the saddle.

I’ve personally tried many variations of this kind of comfort-enhancing tech, from Pinarello’s K8-S suspension , Specialized’s Zertz inserts (but not the new version of the Roubaix with front suspension ), Canyon’s trick VCLS seatpost and varying carbon layups ( see Lapierre’s revamped Sensium for one example ) that purport similar claims of increased compliance without sacrificing speed, and this has to be the most effective overall setup I’ve experienced.

Perhaps the best thing about it is how adjustable it is. Throw the Domane SLR into maximum compliance mode, and it’s better than anything out there for sheer vibration dampening. Stick it into minimal flex setting (still fairly vibration-nulling) and it’s 99% as responsive as, for example, the incredibly impressive Sensium that left me shocked with how racy an endurance bike could feel.

Why just 99%? The Domane SLR doesn’t quite take my breath away as the Sensium did, but it does get right to the heart of vibration-dampening in a way that Lapierre, Pinarello and Canyon’s endurance bikes just can’t match. It’s exceptionally smooth.

That’s helped by the newly-installed IsoSpeed setup at the front end. It’s brilliant at working with the IsoSpeed handlebar (a strip of rubber runs inside the carbon here) to wash out buzz at the front end. The introduction of the front IsoSpeed came as a response to feedback from consumers who said the previous Domane felt a little too harsh at the front, exaggerated by the smooth rear. Now Trek have attempted to balance the front and rear, and it’s truly effective in providing an all-out smooth ride.

However, that does have the effect of isolating you from the road a little, rather than feeding back the nuances that come with every pedal stroke. That’s not to say you’re uninvolved in the experience, but it does have the effect of slightly isolating you from the bike beneath you, allowing the frame to take the punishment the road surface is giving without directing that harshness to you. For some, the ride may feel a little vague but it is undoubtedly a plush ride. Trek’s IsoSpeed technology has absolutely moved the game on for carbon endurance frames in terms of smooth riding, and this is where it shines the best.

Coupled with the geometry, which relaxes the handling by extending the wheelbase, and the Domane SLR is an incredibly easy bike to ride – it’s supremely smooth, well-mannered and remains planted to the road over tricky surfaces. There are concessions to be made with a geometry like this, and it loses an element of the responsiveness and agility that adds excitement to the ride, but on the flip side it’s a very easy-going companion to spend the day with, and that’s the goal for most endurance bikes. As we’ve already mentioned, Trek do sell the Domane SLR in a Pro Endurance geometry with a more aggressive fit and sharper, more agile handling, but that comes at a premium and is only available with the rim brake frame.

That’s not to say the Domane SLR won’t perform when the heat is turned up, however – the frame, ultimately, is one designed with performance in mind. Our test loop takes in a number of local climbs and, giving it the full treatment, the power is sent through the beefed bottom bracket with excellent efficiency. In this area, it remains a very stiff bike, and whether attacking a steep ascent or spinning up a shallower climb, it’s happy to take the punishment. The SLR gathers its speed in a more relaxed, linear – and less spiky – manner than a razor-sharp bike, but the BB90 bottom bracket oversized tube profiles ensure it’s not going to leave you wanting more when putting the power down. If fast but smooth and controlled riding is what you want, then the Domane SLR delivers that in spades.

The build – full Ultegra, discs and wide tyres

As we’ve already mentioned, the Domane SLR is available with rim and disc brakes, with six builds from £3,600 to £7,600 – the Domane SLR 6 Disc here comes in at £4,000. The Domane range also includes the SL, which gains the new front IsoSpeed decoupler but retains the existing, non-adjustable rear IsoSpeed, with options from £2,500 to £3,500. There’s also the Domane S, which ‘only’ has the non-adjustable rear IsoSpeed of old, and is priced between £1,400 and £2,000. Let’s not forget the updated, aluminium Domane ALR , either, which will set you back between £1,300 and £1,100.  

The SLR 6 Disc is built with a full mechanical Ultegra groupset (compact chainset with 11-28t cassette, making for a wide spread of gears ideal for an endurance bike), teamed with Shimano’s flat mount RS805 hydraulic disc brakes. It’s a recipe for reliable and impressive performance on all fronts. We probably don’t need to describe the performance of Ultegra, except to say it’s excellent as ever, but the discs certainly deserve more of your attention.

The undoubted performance benefit of discs in poor conditions is clearly apparent when riding – from the great effectiveness when the rotors are wet or greasy, to the incredibly tactile modulation once the discs are under load. Whether or not the UCI re-starts its disc brake trial, discs remain an ideal option for an endurance bike and riders less concerned by the rules set by the sport’s governing body, and more the real world performance on slick roads and steep descents.

That being said, discs won’t appeal to everyone. There remains the issue of the comparatively sudden initial application of hydraulically-actuated disc calipers against rotor – not a problem, per se, but something to get used to compared to the gradual and tactile application attributed to upper-echelon rim brakes. There’s extra weight, too, and while the Domane SLR 6 Disc isn’t overly portly at 8.3kg, it’s certainly not light for a bike of at this price.

The wheels are tubeless-ready Bontrager Affinity Comp hoops. They reliable and roll well but aren’t going to set the world alight.  The Domane SLR Disc frameset also has stacks of tyre clearance and Trek have taken full advantage, fitting 32mm tyres (the non-disc SLR gets 28mm rubber) for maximum comfort.

In truth, they also roll quickly – if you’ve been used to riding 23mm or 25mm tyres then you might expect them to be splashy and slow,  but they’re nothing of the sort. Stick 60-70psi in them, and they’ll look after you all day long while instilling confidence in the bike’s adhesion to the road on descents, as well as start the whole vibration-dampening chain in the bike.

Those wide tyres really add to the plushness of the bike, if also contributing a little to the slightly isolating ride quality. During the test period, I installed a set of Challenge Paris-Roubaix 28c tyres on the rims for comparison, blew them up to 80psi and immediately felt a sharper interaction beneath me. Either way, Trek have set this bike up really well for endurance riders, with comfort and speed coming hand in hand. Throw in the fact that 32mm tyres means you can point the Domane SLR off-road, and you’re opening up plenty of possibilities. 

Despite all that, it’s the handlebar that really shines. Thanks to the IsoCore rubber inserts, wrapped in carbon, you could install them on any bike and improve its vibration dampening qualities. The shape is as good at it comes, allowing easy access to all parts of the handlebar, while being very comfortable to hold during long days in the saddle. This is especially the case when you rest your hands on the tops, thanks to slightly wider shape for easier grip on rough surfaces. Throw in the comfortable Bontrager Affinity Elite saddle with titanium rails and shallow cutaway for perineal relief, atop a Bontrager-branded carbon seatpost, and your contact points are well-sorted.

The Trek Domane SLR 6 Disc is not only the most comfortable endurance road bike I’ve ridden, but it’s all-round quick and a fantastic looking machine with a smart spec. The rear IsoSpeed offers a tuneable range of compliance and the front IsoSpeed, combined with the IsoCore handlebar, looks after the front end admirably. Riders in search of a more agile and aggressive machine may be better suited by the Endurance Pro geometry – and we’d like it introduced as an option on this frame – but for endurance riders in search of a confidence-inspiring, disc-equipped machine which delivers comfort on tap then the Domane SLR Disc is among the best out there.

• Supremely comfortable; adjustable rear compliance
• Stable and relaxed geometry for endurance riding
• Very stiff and efficient when putting the power down
• Excellent spec; slick shifting, all-weather braking, plush tyres
• Some riders might find the plush ride a little isolating
• Not particularly light

Trek Domane SLR review

Slider down the side of seat tube lets you alter the ride quality

• Sign up to our newsletter Newsletter

Test bikes come and go here at Cycling Weekly, but the Trek Domane SLR was a bike that I kept coming back to throughout the summer between testing other models, long after I’d formed a definitive opinion on it and had finished making my notes. The ability to change the bike’s ride characteristics using a little slider on the side of the seat tube might sound gimmicky, but you can’t argue with performance. This is a bike with a rear end that can be compliant to smooth out rough roads, or stiff for efficient power transfer when riding in the saddle. This is complemented by technology at the front of the bike that while non-adjustable still manages to smooth out vibrations without detracting too much from a design geared towards racing. If you’re after a bike that will put you at the front of races and keep you comfortable on six, seven, eight-hour rides, then the Trek Domane SLR is hard to beat

Incredibly versatile

Comfortable on long rides

Great power transfer

Excellent wheels

Tyres cut easily

No adjustability on lower models

Over the last few years, the original Trek Domane has established itself as one of the leading endurance bikes on the market.

Now Trek has released a new model, with a standout feature that sets it apart from everything else available today.

The standout feature of the Trek Domane SLR is the adjustable rear IsoSpeed decoupler. In effect the bike has an extended seatpost that sits behind a cut out seat tube, with the two attached using a pivot bolt at the junction with the seatstays and the top tube, and a second bolt that also doubles as the bottom bottle cage bolt.

This apparently gives the new bike an adjustment range of 20 per cent of compliance. This means that the bike can go from being as stiff and relatively uncompliant as Trek’s other race bikes, the Madone and Emonda , to being up to 14 per cent more compliant than the old Domane .

Adjustment is done via a slider which runs between the two tubes: move the slider to the top to get a stiffer, less compliant ride similar to the Madone and Emonda, and move it to the bottom to get the most comfortable rider that the Trek Domane SLR can offer.

A similar IsoSpeed technology is used at the front, where the fork steerer tube is isolated, allowing it to rotate independently. This means a front end that is, according to Trek, 5-10 per cent more compliant than that of its predecessor.

Aside from IsoSpeed there are a number of extra comfort features built into the new Trek Domane SLR. First up are the IsoCore handlebars, which have a rubber compound woven into the carbon-fibre to dissipate road vibrations, meaning a claimed 24 per cent benefit over aluminium bars and 20 per cent benefit over standard carbon bars.

The bike also has a new IsoSpeed fork (with 12mm thru-axles on the disc brake versions), with the positioning of the dropouts apparently increasing compliance by 7 per cent compared to a standard road fork.

Other than the IsoSpeed technology, the Trek Domane SLR comes with a whole host of other features that come together to create what Trek reckons will be its most versatile road bike ever.

For all that talk of extra compliance and comfort, Trek has also redesigned the down tube of the new bike, giving it a curved look and making it wider, apparently meaning better power transfer.

Specification

Our Domane SLR test bike came with a top-end build that meant a Shimano Dura-Ace groupset with rim brakes rather than discs.

For those deciding whether to make the switch, there are a big selection of disc brake bikes throughout the Domane range, but it is good to see that Trek, unlike Specialized with its new Roubaix, is still giving customers a choice of which braking system to go with.

The wheels were a pair of tubeless-ready Bontrager Aeolus 3 clinchers topped with 28mm Bontrager R3 Hardcase Lite tyres. While the wheels were excellent, providing a fast yet comfortable ride, the tyres cut very easily and would be the first thing we would change.

I came to the Trek Domane SLR with two preconceptions; firstly that it is an endurance bike, and secondly that the slider was a gimmick. On both counts the bike proved me wrong.

The difference in the ride between having the slider at the top and having it at the bottom is profound. Move it all the way to the bottom and you get a super-comfortable endurance bike with a compliant rear end that is the equal of any other endurance bike on the market.

I’ve ridden this bike on the cobbles of Flanders , and with the slider at the bottom it was seriously smooth, while the IsoSpeed system at the front helped to keep my hands and wrists in decent shape, even while riding without gloves.

But move the slider and the Domane SLR is no longer an endurance bike. Back in Blighty, and with smoother roads and faster rides on the agenda, I moved the slider all the way to the top and turned it into an out-and-out race bike.

Power transfer through the bottom bracket and rear end is absolutely superb, with the bike rocketing along even with the 28mm tyres.

At the front, when sprinting I didn’t experience the handlebars bobbing up and down as expected, although I can’t claim to have fully pushed this to the limits as I’m a relatively light rider.

In practice I found myself generally setting the slider at its mid-point and leaving it there for most rides, but it’s always nice to have the option to switch things up or down to create a horse that will run well on any course.

How to ride the cobbles

I’m torn over the value on offer by the Trek Domane SLR. Seven thousand pounds is a lot of money to spend on a bike, but the Trek goes a long way to justifying that price tag with the ability to double up and perform just as well in a road race as it would on a 200km Audax over sketchy lanes.

My frustration is that the slider that makes this bike so versatile is only available on top-end Domanes — the most affordable bike with this technology costs £3,600 and comes with basic alloy wheels and second-tier Shimano Ultegra .

Trek domane 3rd party reviews, 2022 trek domane review - a tpc quick-take.

• IsoSpeed Technology: A standout feature, the rear IsoSpeed decouplers absorb fatiguing road chatter. They make the ride unmistakably smooth, like riding on a cushion of air.
• Storage integration: The built-in storage compartment on the down tube is genuinely useful. It beats having to strap a saddlebag to the frame and clutter the bike.
• Versatility: Generous tire clearance (up to 38mm without fenders) and the overall design mean the Domane is adept at handling both tarmac and light gravel. It opens up avenues for exploration beyond the usual road routes.
• Endurance geometry: Maintaining the spirit of the Domane lineage, the 2023 version offers a comfortable, upright riding position suited for long rides.
• Weight: (18.5 lbs size 56cm) The Domane, with all its tech and features, is on the heavier side, especially in its base models. This might not be a concern for the casual rider, but weight weenies might raise an eyebrow.
• Cost: The technology packed into the Domane makes it a bit pricey. While you get a lot for your money, it might be overkill for those not intending to utilize all its features.
• Aero compromises: Compared to race or aero road bikes, the Domane doesn't cut through the wind as efficiently. It's built for comfort over speed, and it shows.
• Over-engineering for some: While tech enthusiasts might rejoice, the myriad of features could be overwhelming for someone looking for a simple endurance experience.

Bottom Line:

• Trek Domane SLR 6 Gravel Disc 2018
