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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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).

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.

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.

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.

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.

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.

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.

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 .) 

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.

8.23kg isn't 'lightweight'... that's porky. 1.4kg over the UCI minimum!

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.

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

• Sign up to our newsletter Newsletter

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.

New SL frame has lost some of the excitement of the existing Émonda

Heavy for a 'climbing' bike

You can trust Cycling Weekly. Our team of experts put in hard miles testing cycling tech and will always share honest, unbiased advice to help you choose. Find out more about how we test.

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

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.

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.

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.

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.

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'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.

Trek Émonda comparison review: SL6 versus SLR6

In developing the Émonda, Trek devoted considerable resources to designing a lightweight race bike and trumped the industry with a 690g frame. CTech editor Matt Wikstrom takes a close look at the new bike and assesses the influence of different grades of carbon fibre by comparing the mid-level Émonda SL6 with the upper-level SLR6.

Trek is well known for its Madone and Domane road bikes but neither was ever designed as a lightweight race bike. So in 2012, the company set out to see what it could achieve and came up with the Émonda. The development process required over 30 months but the result is currently the world’s lightest production road bike. At 4.65kg for a size 56cm bike, the Émonda SLR10 trumps the previous title-holder by almost 1kg, but at a significant cost: $17,999.

There are, of course, more affordable versions of the bike yet Trek believes that the Émonda range is the world’s lightest production road line . There are over a dozen models in the Émonda range including women’s-specific versions and custom builds via Trek’s Project One portal . Variations in parts specifications account for some of the differences between each model, but there are also three different versions of the frameset (designated S, SL, and SLR) that differ in carbon fibre grade, country of manufacture, and ultimately, final weight.

Trek uses five different grades of carbon fibre for frame construction that vary in weight, strength, stiffness and cost. At one end of the spectrum there is 300 series carbon, a cost-effective blend, and at the other there is 700 series carbon, a high-cost, low-weight, military-grade blend.

As the base model in the range, the Émonda S is made in Taiwan from 300 series carbon with a simplified design (e.g. a standard seatpost is used rather than semi-integrated design) to reduce production costs.

In contrast, the Émonda SL and SLR share many of the same design features (such as a semi-integrated seatpost) however the SL is manufactured in Taiwan from 500 series carbon while the SLR is manufactured from 700 series carbon in the U.S.A. The use of the highest-grade carbon affords the SLR a weight saving of over 300g when compared to the SL but almost triples the price of the frameset.

While weight was an important design imperative for the Émonda, Trek spent a considerable period road testing the new bike to refine its handling characteristics while paying attention to its stiffness. Riders from Trek’s professional team were instrumental in determining the value of each refinement but engineers were also guided by data collected from strain gauges and accelerometers fitted to prototypes.

CT’s roving reporter Dave Everett attended the launch of the Émonda last year and was able to take one ride on the SLR8 . While his report served as a good introduction to the Émonda, the new bike deserved a longer look. In this review, I spend a lot more time on the Émonda, and thanks to Trek Australia , compare two models — SL6 and SLR6 — to learn more about how different grades of carbon fibre affect the performance of the bike.

Before the ride

In developing the Émonda, Trek’s engineers pared away at the frame and forks until they arrived at the minimum structure that satisfied all of their performance and safety criteria. The result is a frameset that is noticeably skinnier than the Madone and Domane .

Like the Madone and Domane, the Émonda SL and SLR framesets utilise a BB90 bottom bracket and E2 headtube. At 90mm wide, the BB90 bottom bracket provides a broad footing for the downtube and chainstays to help the stiffness of the frame. The E2 headtube also helps the stiffness of the frame with an oversized lower headset bearing and tapered fork steerer.

Trek further refines the design of the SLR with an asymmetric steerer that is wider from side-to-side and skinnier from front-to-back. The difference provides extra stiffness for cornering while affording some compliance to soak up road shock.

The Émonda SL and SLR also inherit the semi-integrated seatpost design that was introduced with the Madone. A seatpost cap fits over an extended seat tube and offers a range of 10cm for saddle height adjustment. Trek offers a choice of two lengths for the seatpost cap (135mm and 175mm) along with two offsets (5mm and 20mm) to help with refining the fit of the bike.

Both framesets provide internal routing for the gear and rear brake cables, with interchangeable cable stops and ports to suit mechanical and electronic transmissions. There is also an adjustable chain keeper that is integrated into the seat tube while the left chainstay is ready to accept Trek’s DuoTrap S speed/cadence sensor .

Aside from the difference in carbon fibre blend and country of origin, the SLR frameset is further distinguished from the SL in a number of small ways. I’ve already mentioned the asymmetrical fork steerer above. Another difference lies with the brake caliper mounts: the SLR frameset uses direct mount calipers front and rear, while the SL uses conventional calipers.

The front derailleur mount also differs: the SL frameset has an alloy fitting that is riveted to the seat tube while the SLR has a carbon mount that is molded into the frame. Finally, the SLR frameset is offered with a choice of Trek’s H1 or F2 fit, while the SL is only available with a H2 fit. The difference between the two is in the length of the head tube, which is 30-35mm taller for the H2 fit at every frame size (see chart below).

There is a choice of up to nine frame sizes for the Émonda, as shown in the table below:

The range of frame sizes varies, depending on the model and fit of the frame. The SL6 is offered in sizes 47-62cm with a H2 fit only while the SLR6 is available in sizes 50-62cm with a H1 fit and 47-64cm with a H2 fit. Trek’s H1 fit can be considered very aggressive and race-oriented, affording plenty of handlebar drop. In contrast, the H2 fit is more moderate but riders looking for a more upright position will be better served by the geometry of Trek’s Domane. Visit Trek for detailed geometry charts for the SL6 and SLR6 .

The styling of the Émonda is very clean and simple with inviting lines that flow from one point to the next. The seat tube junction in particular is elegant and I like the way the seat stays seem to sprout with energy for the dropouts.

Trek keeps the paintwork simple with a minimum of decoration though the gloss paint adds some luxury to the final result. The Émonda SL6 is currently available in a choice of two colours (Matte Trek Black with Gloss Trek Black logos, or, Viper Red with Trek Black logos) compared to one for the SLR6 (Crystal White with Argent Silver logos and Trek Cyan details). However, there are many more paint finishes available for the SLR via Project One .

The SL6 and SLR6 are both dressed with Shimano’s mechanical 11-speed Ultegra groupset and a suite of Bontrager components but there are some distinct differences between the two bikes. For example, the SL6 uses Bontrager’s entry-level Race wheelset while the SLR6 gets an upgrade with a Race Lite wheelset that is lighter.

Similarly, the SL6 is supplied with a Bontrager Paradigm Race saddle with chromoly rails while the SLR6 gets a Paradigm RL saddle that has hollow titanium rails. There is also a difference in brake calipers, where the SL6 has standard Ultegra calipers while the SLR6 uses Bontrager Speed Stop calipers.

All of these differences, from the grade of carbon fibre to individual parts, provide significant weight savings for the SLR6 when compared to the SL6. The SL6 sent for review (size 54cm, H2 fit) weighed 7.42kg sans pedals and cages while the SLR6 (size 54cm, H1 fit) weighed 6.68kg. The savings (740g) can be attributed largely to the SLR frameset (~300g) and the Race Lite wheelset (300g), with smaller weight savings provided by the shorter head tube and a lighter saddle.

Unsurprisingly, the weight savings come at a significant cost: the Émonda SL6 has a recommended retail price of $3,699 while the SLR6 retails for $8,499. In both instances, the frames come with a lifetime warranty while the forks and all Bontrager parts are covered by a two-year warranty. For more information on the Émonda range, visit Trek .

After the ride

After spending the day riding an Émonda SLR8 last year , Dave Everett found that “the first noticeable thing for me was not so much the weight but how planted the bike felt on the road.” Later though, once he found himself in hillier terrain, Dave was “definitely using the big chainring a lot more” than he normally would thanks to the low weight (6.15kg) of the bike.

Like Dave, I wasn’t wowed by the weight of the SL6 or SLR6. Instead, the Émonda was surprisingly ordinary, even mundane, compared to its marketing hype. Of course, there was more to discover, but after my early rides on the SL6 and SLR6, all I could say was that both bikes offered a very smooth and refined kind of ride that I’ve long associated with Trek’s bikes.

A “refined kind of ride” is not necessarily a compliment though. For those riders that like the bike to disappear beneath them so that they remain unaffected by road feedback, the Émonda should have plenty of appeal, regardless of whether it is the SL or SLR. However, I found myself wanting more from the bike, and while I could criticise the Émonda as being “dead” or “unlively”, that wouldn’t be fair. Instead, I’ll say this: riding an Émonda is like visiting a library to enjoy the quiet.

The steering and handling of the Émonda was very stable and predictable. As such, the bike is incredibly easy to ride. The bike obeyed my every instruction and while the steering tended towards slow, I didn’t find it required any extra effort to hold a line through sharp corners. I wouldn’t recommend the bike for criterium racing but then there isn’t much about the Émonda’s styling or marketing that would likely attract a dedicated criterium racer.

Neither the SL6 nor SLR6 felt like a particularly light or responsive climbing rig. Capable, yes, but still some distance from ever being explosive. What seemed to be missing was any great sense of the bike’s stiffness. It’s not that the bike was too compliant, but rather, I wasn’t getting any feedback from the bike in order to judge its performance. Thus it seems the Émonda is defined more by the absence of any sensation rather than what can be felt by the rider.

The Émonda was well suited to long rides. The bike doesn’t rattle or chatter, even on rough roads, and I found the hours passed by with ease as the bike continued with steadfast assurance. I found myself re-evaluating the subdued ride quality as a comfort, like the support and encouragement from a devoted friend. After all, there’s no need for showmanship on a long ride, just steady commitment from the rider and the bike, and the Émonda was prepared to keep going for as long as I wanted.

By taking turns on the SL6 and SLR6, and then swapping the wheelsets between each bike, I found that the SLR6 was a stiffer bike. It was only a mild difference, but it could be felt when rising out of the saddle on a climb, traversing rough roads, and as a little feedback from the road. Overall, it provided the SLR6 with a racier feel than the SL6, but I must stress, it was very mild. Switching to stiffer mid-profile carbon wheels ( Curve 38mm clinchers ) enhanced this sense a little more but the wheels weren’t able to transform the Émonda into an aggressive race bike.

The Domane has a strong reputation for its comfort but the Émonda shouldn’t be overlooked, especially the SL series. I found myself marvelling at how well the SL6 was able to soak up every crack, bump and rut. Furthermore, there was a good balance of compliance between the front and rear of the bike. Adventurous riders that enjoy demanding terrain may find the Émonda lacking, otherwise the bike is well suited to a wide variety of terrain.

The SL6 had a lot in common with the SLR6. The overall ride quality was very similar while the steering and handling were identical. I’ve already mentioned that the SLR6 was marginally stiffer; it was also marginally more agile, but that was due largely to the lighter wheelset. Indeed, swapping wheelsets between the two bikes improved the SL6, however it made no difference to the stiffness of the bike.

Finally, I’m pleased to report that Bontrager’s new direct mount Speed Stop calipers are a significant improvement over the previous iteration supplied with the Madone . The calipers were smooth and effective with plenty of bite but they didn’t suffer any of the heavy effort that defined the last version. Indeed, I couldn’t find anything to separate the performance of Speed Stop calipers from the standard Ultegra brakes fitted to the SL6.

My only complaint is with the way the inner cable is routed: it ends up between the tyre and the brake arm to rest upon the brake pad. Cutting the cable short removes any risk of it getting caught against the rim but then is too fiddly to hold when re-adjusting the cable.

Summary and final thoughts

The Émonda has been positioned by Trek as an ultralight bike, purpose-built for climbing, with a strong emphasis on race performance. I don’t have a quarrel with their claims or strategy but the bike is much more versatile than a dedicated climbing rig. The ride quality is easy to like and the steering and handling ensure its reliability in essentially any situation, so while it won’t satisfy buyers looking for extremes in performance, it’s hard to see how it will disappoint anybody else.

The differences between the SL6 and SLR6 were modest at best. Some were a matter of the parts specified for each bike, but fundamentally, the SLR frameset is lighter, stiffer and more race-oriented that the SL.

It is interesting to note that most of the weight savings offered by the SLR6 can be obtained for an Émonda SL by upgrading from the SL6 to an SL8 (RRP $4,999) and substituting the stock Race wheelset for the Race Lite version without spending any more than $6,000. I’m not criticising the price of the SLR though, just highlighting what is perhaps the Émonda’s greatest strength, which is Trek’s range of models and options for the bike.
