trek emonda sl6 max tire size

• Émonda SL 6 Disc Pro

"One of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero"

"I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes."

"It's an incredible update from Trek"

"The updated Emonda packs one helluva punch, and Trek has a winner on its hands. The integrated cockpit is nice and all, but the real win is the H1.5 fit, which makes the Emonda feel more stable while maintaining the aggression and responsiveness of previous Emondas. That, coupled with a lightweight construction, comfortable ride, and aerodynamic shaping, brings Trek's top of the line climber from a very good bike to an excellent one."

"The Emonda is still light, and it’s still stiff, but now there’s an extra dose of free speed"

"Overall, Trek has done a solid job here of updating the Emonda, infusing meaningful improvements in several key areas, but without breaking the basic formula that has made the bike so popular."

2021 Trek Emonda SL 6 Pro review

Trek's climbing specialist has been re-imagined as a do-it-all race bike.

Felix Smith / Immediate Media

Amazingly stiff ride; race-ready long and low fit; exceptionally fun to ride.

25mm tyres exaggerate harsh ride and harm performance on imperfect road surfaces; weight isn't competitive for price.

The new 2021 Trek Emonda sees a shift away from a purely climber-focussed bike to a more all-round package with the de-rigueur aero shaping to match.

We have two bikes in for review. My colleague, Warren, has the top-end 6.9kg Emonda SLR 9 model with all of the bells and whistles, and an outrageous £9,700 price tag .

I have been testing the Ultegra R8000-equipped 2021 Trek Emonda SL 6 Pro.

The SL-level Emonda is based on Trek’s OCLV 500 carbon layup, which adds roughly 445g to an unpainted frameset in an unspecified size compared to the top-end model.

You do, however, get the exact same geometry and frame shape as the SLR-level Emonda, so the differences should largely boil down to weight alone.

• Trek Emonda SLR 9 eTap first ride review

At £3,350 ($3,799 / €3,799 / AU$5,499), the SL6 Pro is by no means cheap, but represents fairly good value for money in the context of the wider market

For that cash, you get a full Ultegra R8020 groupset , a Bontrager Aelous Elite 35 carbon wheelset, a perfectly inoffensive alloy cockpit and a very plush Bontrager saddle. The bike weighs 8.13kg on the nose with no pedals.

Picking two comparable bikes, the Giant TCR Advanced Pro 2 Disc costs roughly the same (£3,499) for a broadly similar build, as does the Rose X-Lite 6 (~£3,450).

Trek has significantly altered the geometry of the Emonda for 2021, and it is now only available in the brand’s middle-of-the-road H1.5 fit.

H1.5 sits pretty much in the middle of Trek’s super aggressive H1 geometry and its endurance-focussed H2 fit.

The resulting shape strikes a nice balance between real-world usability while allowing the sportier riders among us to get a low and fast setup should they so wish.

The stack for the new Emonda is on the lower end of the spectrum for a 56cm bike at 563mm. The reach is fairly average, at 391mm for a 56cm bike. The 56cm bike ships with a 100mm stem.

While the reach of the frameset is fairly average, when matched with the 42cm-wide Bontrager Elite VR-C bars, which have a hefty 100mm reach, the fit of the bike feels suitably long and low.

I really like the overall profile of these bars – there’s loads of room in the drops so you can actually spend some time down there comfortably without your hands getting smooshed up, and the extra reach offers additional useful hand positions.

Adding reach to the bars (rather than increasing the length of the stem) also means the tops stay a touch closer to you, giving a really comfortable position for seated climbing.

The ride of the bike is exceptionally stiff and incredibly fun in the way that a proper race bike can be.

It’s got that addictive ultra-efficient feel with a totally unyielding pedal response that is amazing on the climbs – you are giving up nothing to the frame when mashing yourself into a lactic oblivion.

I dare say the overall feel is almost a little old school, with a super stiff ride that’s reminiscent of early carbon bikes.

This will be polarising for some riders, but I personally really like it. It feels properly rapid and responsive, and going fast is never not fun.

While perhaps divisive, this super stiff ride also goes some way to differentiate the bike from the others in Trek’s lineup.

The line between the Emonda and Madone – and to a certain degree, the Domane – is now fairly blurred with this new bike.

But by keeping it simple, with no ISOSpeed squashiness, a racy ride and a lighter overall package, the Emonda stands out in the range.

That stiffness also translates into a really engaging and fun ride on the descents. The bike shrugs at irresponsibly heavy braking into corners, remaining accurate and giving – yes, I really am going to say it – a really feedback-rich ride. It’s a total hoot.

It’s no surprise that this stiffness results in a firm ride.

It’s not a rough ride, per se – the bike still provides that pleasingly damped feel that any quality carbon bike gives on imperfect surfaces, and the integrated seat mast brings a degree of rear end comfort.

However, on larger bumps, the front end can feel quite jarring. The alloy bars will contribute to this, but the stock 25mm tyres are the main culprit.

25mm wide tyres were considered progressive a few short years ago, but the majority of new road bikes these days ship with 28mm tyres (or even larger) and not without good reason.

Wider tyres have consistently been shown in testing to have lower rolling resistance than narrower tyres and, as they can be run at lower pressures, they also improve comfort. Being more comfortable means less fatigue, which means increased speed.

This is well-trodden ground, so to see 25mm tyres here is a little bit disappointing – other bikes in the Emonda range feature 28s, and I’ve always admired Trek for boldly speccing 32mm tyres on the Domane, so to see narrower rubber here feel like a bit of a cop-out.

Trek is clearly trying to pander to the hill climb kids with the tiny reduction in weight 25s will offer, but 28s would be better for the majority of riders in nearly all situations.

Keen to see how much of a difference wider tyres would actually make, I swapped the stock Bontrager R2 Hard-Case Lite tyres in favour of a pair of Panaracer Race D Evo tyres. These measure bang on 28mm when inflated to 70psi on the Bontrager Aeolus Elite 35 wheels.

Unsurprisingly, the wider tyres smoothed out the ride of the bike significantly without making the ride feel mushy – you can focus on getting the most out of the bike’s stiff frameset without having to worry so much about potholes or broken road surfaces. The larger tyres also improve grip on descents.

They also make very light gravel detours a more appealing possibility.

Gravel riding is absolutely one bazillion per cent not within the intended remit of this bike, but the larger volume tyres make short stretches along smooth unsealed rail trails or rough access roads a much less hateful experience.

On a similar theme, I was also a little disappointed to see the bike come set up with tubes.

The likes of Giant are now shipping complete bikes tubeless out of the box and, regardless of which side of the tubeless vs. tubed debate you sit on, including tubeless tech as stock adds value to a bike.

Given the new Aeolus 35 Elite wheels are tubeless-compatible, it’s disappointing that the included tyres aren’t at least tubeless-ready.

As mentioned, the bike has been doused in a liberal helping of aero sauce, and the new bike is claimed to sit between the outgoing Emonda and the Madone in terms of aero performance.

There’s no way I can quantify these claims, but the bike does feel fast on the flats. I suspect that has more to do with the fact the bike’s geometry means it’s possible to get into a properly long and low position, so I’ll leave it up to you to decide whether you believe Trek’s claims – or whether you care.

Not that it has any bearing on performance, but the aero shaping has resulted in a bike that looks fast. I’m fond of the overall shape of the bike and I’m glad to not see dropped seat stays here. The lines are classic and the traditional cockpit doesn’t look out of place either.

Trek clearly doesn’t want you to forget you’re riding one of its bikes judging by the sheer size of the logo on the down tube. It is so over the top and a bit daft, but I kind of dig it – it’s like a postmodern statement, the David Byrne big suit of bicycle logos .

I also think the paint job looks really nice for what is, in the context of this model range, a ‘budget’ bike.

A surprising standout from the bike is the Bontrager Aeolus Comp saddle.

Every man and his dog has thrown his hat into the short nose and stubby saddle game, and I’ve tried a fair few now, but I think it’s a toss-up between this and the Pro Stealth Superlight for my all-time favourite .

Trust me when I say this is very high praise because I love the Pro Stealth. The Aeolus is squashy, comfortable and perfect for my peach. I can’t believe it has taken this long for saddles to get this good.

The bike is built around a full Shimano Ultegra R8020 groupset . It’s nigh-on impossible to level criticism at R8000, offering nearly all of the performance of Dura-Ace at a considerably lower price point.

The 52/36 crankset is paired with an 11-30 cassette. For a go-fast all-round climb-friendly bike, this is perfect.

However, it’s worth noting that the bike is equipped with a short cage mech, which officially limits the drivetrain to a 30t cassette. This means you would have to go for a smaller set of chainrings if you require lighter gearing.

Even so, the gearing has more than enough range to climb comfortably in the saddle on most climbs.

The SL6 Pro is the ‘cheapest’ bike in the new Emonda range to feature carbon wheels.

At 35mm deep, the Aeolus Elite 35 should, in theory, give a bit of aero advantage without sacrificing too much on the climbs in terms of weight.

A 35mm wheel is unlikely to present serious problems in crosswinds, and they feel perfectly well-mannered and stiff. The wheels are based on DT Swiss’ Ratchet EXP freehub, which are easy-enough to service with widely-available spares.

Again, I’m a bit miffed these aren’t set up tubeless out of the box. It would allow you to run lower pressures, improving comfort and grip, which is never a bad thing.

2021 Trek Emonda SL 6 Pro conclusion

Make no mistake – the Emonda is an uncompromising race bike, and it’s all the better for it.

In a world of squashy do-it-all bikes, the Emonda’s wonderfully moreish super stiff ride stands out and I’ve really enjoyed my time testing it.

Speccing standard 25mm clincher tyres in 2020 is an odd move, and the weight for this particular build isn’t that competitive.

You also lose out on some (claimed) aero benefit with the standard cockpit versus the fancy new integrated Bontrager Aeolus RSL VR-C bar-stem combo. But, if you’re anything like me and enjoy endlessly tweaking your position and cockpit setup, this might not be such a bad thing.

Jumping up to the Emonda SL 7 (£4,850) would get you an Ultegra Di2 groupset, Bontrager Aeolus Pro 37 wheels and the integrated cockpit, but I’m not convinced the extra expense would be worth it.

A few small spec niggles aside, if you’re after a delightfully fun go-fast race bike, the 2021 Trek Emonda SL 6 Pro is very unlikely to leave you wanting.

Trek Émonda Bikes Compared: Which One to Choose?

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

In this article, I’ll help you navigate the Trek Émonda aero road bikes by comparing the Émonda SL 6 to SLR 9 .

You will also learn:

• Who are they best suited for?
• Why I think you shouldn’t buy Trek Émonda with SRAM groupset.
• And which model gives you the best value for your money?

KEY TAKEAWAY

Trek Émonda bikes are ideal for climbing and hilly terrain. They are the lightest bike family of all Trek road bikes . The models differ in components (e.g., electronic shifting) and frames. The more expensive ones are usually lighter and have a higher-grade carbon frame, but usually diminishing returns.

Let’s dive deeper to help make your decision easier.

This article compares Trek Émonda Gen 6 and 7. The main difference between Émonda Gen 6 and Gen 7 is that Gen 6 has IsoSpeed decoupler, while Gen 7 has IsoFlow.

Trek Émonda ALR 5 to SLR 9

The following table summarizes the main differences between all Émonda road bikes.

Émonda Pros & Cons Summary

I summarized the pros & cons of the Émonda series below.

Émonda Pros

• Lighter than Madone road bikes
• Aluminum and carbon models are available
• Relaxed geometry
• Availability in multiple sizes and colors
• Integrated cable routing
• Lifetime warranty

Émonda Cons

• Slower than Madone road bikes
• Narrow tire clearance (28mm)

Émonda Main Features

Let me now explain the most important features of the Trek Émonda aero bikes.

Frame and Geometry

The Émonda bikes are part of Trek’s road bike lineup . They’re made of aluminum or carbon .

The names of the bikes have abbreviations that refer to the type of material used for the frame:

• ALR  are  aluminum  frame bikes.
• SL are bikes with 500 series OCLV*  carbon (mid-range).
• SLR are bikes with 800 series OCLV carbon (high-end).

*OCLV carbon is Trek’s patented carbon fiber process ( learn more ).

ALR Émondas are great entry-level road bikes , thanks to their affordability. However, they are still a bit more expensive than less-known competitors.

SLs are the best mid-range option. They are slightly heavier than SLRs but about 25% cheaper.

And SLRs are ideal for people who have more money to spend and don’t want to compromise.

Most Émondas are available in 47-62 sizes and multiple colors giving you a wide range of options.

Their geometry is more relaxed than on other racing bikes, so you won’t experience as much strain on your lower back and neck. The following picture shows the comparison with Specialized Tarmac SL 7.

Weight & Aerodynamics

Trek Émonda frame weighs 760g in size 56. The highest-end Émonda even weighs below the UCI 6.8 kg limit. However, low weight is not everything. Stiffness and aerodynamics are also important.

Trek claims Émonda frames are also relatively stiff and aero (of course, less aero than Madone). They are 18 seconds per hour faster at 8% gradients. ( Source ) However, more information on the methodology is not available.

Émondas are so lightweight also due to the absence of an IsoSpeed decoupler that adds weight.

Wheels and Tires

On some Émonda models, the wheels may be different, but typically, they come with Bontrager Aeolus Pro 37 wheels.

Of course, the low-end models have cheaper aluminum wheels . Fortunately, all Émondas come with tubeless-ready wheels. But remember, the tires are clinchers. So, if you want tubeless tires, you have to buy them separately.

One of the things that surprised me is that the lower-end Émondas have 28mm tires, while the higher-end only have 25mm. Most road bikes these days (except for some aero bikes) have 28mm or 30mm tires.

Unfortunately, Émondas only have tire clearance for 28mm tires.

Unsurprisingly, the Émonda bikes have a 2X drivetrain, as is customary for road bikes.

Trek fits them with Shimano and SRAM groupsets, and the number in the bike name indicates the groupset.

• Models ending with 5 use Shimano  105  (R7000) groupset.
• Models ending with 6 use Shimano Ultegra , 105 Di2 (R7100) or SRAM Rival AXS groupsets.
• Models ending with 7 use Shimano Ultegra Di2 (R8100) or SRAM Force AXS groupsets.
• Models ending with 9 use Shimano Dura-Ace Di2 (R9200) or SRAM Red AXS groupsets.

Interestingly, the Émondas with SRAM are heavier than the Émondas of the same series with the Shimano groupset. In addition, those with Shimano are also cheaper.

This is somewhat strange because Shimano retail prices are higher than SRAM. That’s why I recommend choosing Trek bikes with Shimano groupsets unless you prefer SRAM.

TIP : You might also be interested in this comparison of Shimano vs. SRAM .

So, which Trek Émonda bike is the best?

If you’re considering buying an Émonda, I suggest a model with a Shimano groupset. They are lighter and less expensive than the equivalent SRAM models.

For better value, consider the Émonda SL. It’s around 30% cheaper than the SLR but offers almost the same performance. From all models, I believe the Émonda SL 6 Pro with the Shimano 105 Di2 is the best deal.

However, if you don’t want to compromise, go for the SLR, which is more expensive but lighter.

Trek Émonda FAQ

Trek Émonda SL 5 Disc

At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

• Exceptional
• Not so good

Trek's Émonda SL 5 Disc is a solid all-round race bike offering great handling, a stiff platform for performance and a comfortable riding position, plus it's all wrapped up in a minimalistic, clean-looking package. This build isn't exactly lightweight though.

Trek launched this latest Émonda design last year, giving what has always been considered its lightweight climbing machine an aerodynamic makeover that takes it into what I consider quality all-rounder territory.

From a ride point of view, I can't fault it. It's firmer than a lot of carbon bikes on the market, and I kind of like that. Getting smashed about isn't fun, but neither is a bike that mutes all the signals from the road below. The Émonda balances this well.

Stand hard on the pedals for a climb or sprint and the bike feels tight everywhere, although most notably around the bottom bracket area. There is no flex anywhere, and it just eggs you on to keep hammering away when your legs are screaming to ease up.

Chubby chaser

The only downside is that this SL 5 build's weight can just take the shine off. This 56cm model weighs in at 9.16kg, which is on the beefy side for a near three-grand bike.

The SL 6 Pro I rode last year came with an Ultegra mechanical groupset and 35mm deep Bontrager Aeolus Elite carbon wheels, and weighed 8.23kg. It felt much nippier than the SL 5 when it matters.

As an experiment I switched the SL 5's wheels for a pair of 1,400g Scribe Élan Wide+ 42-D wheels I had on test, and that unlocked the Émonda's potential. I'm not saying you should go out and blow £1,190 on newwheels, just that you shouldn't be put off by the standard weight of the SL 5. It can be tweaked without spending a fortune in the future.

On all but the steepest of climbs though, the Émonda doesn't feel as heavy as the road.cc scales would suggest. It still feels nippy as you accelerate out of corners or crest those short power climbs, and it always seems to have an eagerness to keep rolling.

Right angles

The geometry helps too. This is a proper race bike with a steepish 73.5° head angle for quick steering, plus a short 151mm head tube to allow a low front end and a short wheelbase. At just 983mm, this certainly gives it a nimble and flickable feeling in the bends.

On the downhills I found I could let the Émonda go even when the road surface was less than perfect. It just feels really planted, and coupled with that firm frame passing through loads of feedback from the tyres, I left me feeling perfectly in tune with it.

The steering is on the fun side of neutral, and allows you to just point the handlebar and aim for the apex. The Émonda is also very responsive to slight changes in body position if you need to tweak your line or get yourself out of trouble. I found this out when riding somewhere I had never ridden before – a descent which was easily 40mph+ in sections.

The Trek just nailed it, even though I didn't know what was around the next corner. With less caution than I probably should use, I could throw the Émonda through the bends while constantly making little tweaks to my position to line it up for the next one.

The SL 5 is also a quality mile muncher. The firm ride didn't seem to fatigue my joints any sooner than normal, and although the position is racy, it isn't extreme either. I could ride on the hoods for hours without discomfort and made good use of the shallow drops too.

Frame and fork

As I mentioned earlier, the Émonda focuses more on aerodynamics now than ever before, but that doesn't mean it has become a rocket ship on the road. The Émonda is a climbing bike after all, so Trek's engineers have honed in on 'unsteady aerodynamics,' which they say give larger effects at lower speeds when ascending, rather than on curves for cutting through at high speeds in straight lines.

For starters the front end has been made as smooth as possible, with all cables and hoses directed through the head tube into the frame and fork, giving a very clean look. The head, down and top tube junction is large and beautifully sculpted for airflow too. As a whole the Trek has been optimised for 25mm tyres, although it will swallow 28mm with 6mm of space around the tyre.

The integrated spacer is designed to line up perfectly with the frame when the handlebar is pointed straight ahead, although it does limit how far the bar will turn in each direction. It can feel a bit daunting at first – I kept worrying I might not have enough lock to negotiate a tight turn at low speed.

It proved an unfounded worry though, and the only time I reached the turning limit was when trackstanding at the lights.

The top-end Émonda SLRs use a carbon fibre all-in-one handlebar and stem to take things even further, but there isn't the budget for that here.

As for the seatpost, Trek has decided to do things a little differently. The seat tube extends high, up past the top tube by some way. An external seat mast slides over the top and clamps into position, and the seat tube inside the mast allows a bit of flex, which aids comfort.

The top tube flares out at the seat tube junction, which I find I often rub my thighs against. I got around it by running the saddle 5mm further forward, but it's worth bearing in mind if you have large legs.

The frame and fork are created using Trek's 500 Series OCLV carbon fibre. It's a bit heavier than the new 800 Series found on the more expensive SLR range, but still gives a reasonable claimed weight of 1,142g for the frame and 380g for the fork. There are a massive eight sizes available, too, ranging from 47cm up to 62cm.

The Émonda range is now disc brake only, which means you're getting 12mm thru-axles and flat mounts for the disc calipers.

Trek has gone down the T47 bottom bracket route. Standard threaded bottom brackets have the bearing cups sitting outside the frame, which limits the width the bottom bracket shell can be without pushing the Q-factor (the distance between the pedals) too wide.

To allow a wider shell, which in turn lets the down tube, seat tube and chainstays all have larger joins for increased stiffness at this crucial point, many brands use press-fit cups. These sit inside the frame, allowing a wider shell while keeping the Q-factor the same. In the past there have been creaking and wear issues due to slack tolerances between the cups and the frame, though, so some people have fallen out of love with them.

The T47 is kind of the best of both worlds, as the bearings sit inside the frame but they are threaded into place rather than pressed. That gives a better (and easier) fit, but still allows for that wide bottom bracket shell.

To finish everything off, the SL 5 is available in two colours: this Quicksilver/Brushed Chrome, or Carbon Blue Smoke/Metallic Blue, which I reckon looks even better.

Finishing kit

The SL 5 is adorned with a Shimano 105 R7000 11 speed groupset, which cannot really be faulted, either from my own experience of riding it for thousands of miles on test bikes, or from Dave's in-depth review from a couple of years ago.

The gear shifting is precise and works well even under load – especially at the chainset – and the feel at the lever is practically the same as Ultegra R8000.

Trek has paired a 50/34t chainset with an 11-30t cassette, which gives a decent spread of gears for a bike with racing intentions. Crank length is determined by frame size, ranging from 165mm to 175mm.

Alongside the flat mount 105 calipers the SL 5 uses 160mm SM-RT70 rotors front and rear.

Stopping power is great, as is the modulation and control.

If you weren't aware, Trek's in-house kit and component brand is Bontrager, so it's no surprise to find this adorning the Émonda throughout. The Comp VR-C Road is a shallow drop bar with a compact design, making it usable for most riders regardless of flexibility.

There is nothing flash about it, but it is comfortable, has a decent length of central section for computer mounts or lights, and its aluminium construction is stiff enough for out-of-the-saddle efforts.

> road.cc Road Bike of the Year 2020/21

The Bontrager Elite Stem is another component that just gets on with its job. On the 56cm frame you get a 110mm, and it comes with Trek's Blendr compatibility.

This means you get a selection of mounts for various accessories, such as lights and computers, to sit out in front of the stem. On Trek's website it's £59.99 (£30 more than the handlebar), so it's certainly not a budget component.

The saddle is called the Verse Comp and it's a good 'un, at least for me. It's got a swoopy shape I found gave me plenty of different position options (I like to slide back to climb, for instance). It's 270mm long and 145mm wide (155mm on the smaller frames) with steel rails and a central cut-out. It's also compatible with Blendr accessories.

The frame itself is compatible with DuoTrap S, which is a Blutooth/ANT+ sensor which can send all sorts of data and works with Garmin, Bontrager, PowerTap and more, though the sensor is sold separately.

Wheels and tyres

As with the rest of the finishing kit, the wheels are Bontrager. Using their sealed alloy hubs mated to Paradigm SL rims, they have an internal width of 21mm and 24 spokes front and rear. As I mentioned earlier, they are a bit weighty, but they rode well enough throughout the test period, and I had no durability or trueness issues. They are tubeless ready for a bit of futureproofing.

> road.cc's Best Cycling Wheels of the Year 2020/21

I'm a fan of Bontrager's tyres. I've ridden a few, and was impressed when I tested the R3 Hard-Case Lite a couple of years back. The SL 5 uses the entry-level R1 Hard-Case Lite, and it's pretty good. With a 60tpi (threads per inch) casing it isn't the most supple, but it doesn't detract too much from the ride quality.

They roll pretty well too, and grip is more than adequate in both the wet and dry. More importantly though, considering the review period took in the end of winter, they seem robust and suffered no punctures.

Still, as with the wheels the SL 5 deserves better in the long term. If you want to keep things in the Bontrager family, those R3s mentioned retail for £42.99 now, or £52.99 if you want to go tubeless.

Bike prices are all over the place at the moment, and there have been some big jumps in Trek's line-up. That SL 6 Pro I reviewed was £3,350 in 2021, and it's now £3,900 with what looks to be the same build. The frameset has gone up from £2,200 to £2,700. Meanwhile this SL 5 has come through relatively unscathed at £2,750, up just £25 over last year's prices.

Around the time this Émonda was released, Specialized launched its new Tarmac SL 7 (I was lucky enough to review the S-Works model), and it's a similar sort of bike to the Trek. For 2022 Specialized has largely used SRAM components on its road bikes though, so there's no direct comparison with the SL 5.

However, the entry-level Tarmac SL 7 is the Comp model, which comes with a Rival eTap AXS electronic groupset and DT Swiss alloy shallow section wheels for £5,000, while Trek's SL 6 eTap comes with the same wireless groupset and the Bontrager 35mm deep carbon wheels for £4,300.

There is some tough opposition out there though, with Canyon's new Ultimate CF SL 7 Disc featuring a 105 groupset, a full aero carbon cockpit and a claimed weight of 8.2kg for just £2,149.

Giant's TCR Advanced Disc 2 doesn't quite have the aero attributes of the SL 5, but it is considered a very good lightweight all-round race bike. For £2,349 you are getting a 105 groupset, full carbon frameset and Giant's own alloy wheels.

The Émonda SL 5 is a great bike to ride, and that's down to the top-notch frame and fork paired to good quality finishing kit. True, the wheels and tyres can take the shine off of the performance a touch, but that is true of many entry-point bikes. This is a bike that will tackle any kind of topography or race and excel at it. The frameset is great and it's ripe for upgrades over time too.

The Émonda is a classic all-rounder, fun, fast and stiff, although this model isn't the lightest

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 5 Disc is a lightweight carbon road bike with a balanced ride quality, superior handling characteristics and the added benefit of free speed thanks to aero tube shaping. It's a great choice for century rides on hilly terrain, windy flats and speedy descents."

I think the SL 5 is a classic all rounder.

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

This SL 5 model kicks off the SL range, sitting just £25 above the price of the frameset. Going up through the models you find the SL 6 and SL 6 Pro (£3,400 and £3,900 respectively), the SL 6 eTap (£4,300) and the Ultegra mechanical SL 7 (£5,350). Finally you get to the 12-speed Ultegra Di2 SL 7 (£5,600) and the SL 7 eTap, which uses SRAM Force for £6,100.

Above the SL range is the SLR line up, and below you'll find the aluminium alloy range, the ALR.

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

A high quality frame and fork. It feels great to ride and the paint finish is high end.

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: Émonda 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?

With its steepish angles and short wheelbase, this sits very much in the race bike camp.

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

This 56cm model features a stack of 563mm and a reach of 391mm, which is fairly typical for a bike of this size with racing intentions.

Riding the bike

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

It has a firmer ride than a lot of carbon frames, but personally I like that. It feels like a purposeful and aggressive frame without ever feeling harsh and uncomfortable.

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

Plenty of stiffness throughout, most notably at the bottom bracket junction.

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

It does feel efficient, especially considering its weight.

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?

I found the handling quick with a degree of balance to it – it never feels twitchy.

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

I liked the Bontrager saddle. I found it squidgy enough to absorb the bumps, without being so soft you find yourself bouncing around.

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

The stem and handlebar offer stiffness to match the frame, and there's no real sign of flex from the wheels either.

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

The wheels are a bit weighty, so if you can upgrade to something lighter you'll really unlock the performance of the Émonda.

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?

Performance-wise, 105 is probably all the groupset most of us will ever need from Shimano's catalogue. The shifting is great, as is braking power and modulation, and the value is good.

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?

The Bontrager wheels are decent enough. They blunt the SL 5's climbing and acceleration a touch due to their weight, but I can't fault their durability.

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?

Bontrager tyres typically offer decent performance, and so it is with the R1s. Like the wheels though they are a touch heavy and not the most supple.

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

Good quality in-house kit. Upgrade if you want some bling, but there's no real need.

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?

This is well priced against a similar model in Specialized's Tarmac line-up, as mentioned in the review. There is tough opposition from the likes of Giant and Canyon, though.

Use this box to explain your overall score

The Émonda SL 5 is a very likeable bike; it has a solid dependable feel while still maintaining plenty of fun factor. There is some tough opposition out there price-wise, but would I feel shortchanged by the Trek? No. It has a quality ride feel and a quality build, and I enjoyed every mile I covered on it.

The aggressive and versatile Émonda SL 6 combines the stiffness you’d expect from a top-of-the-line race bike, with big tire clearance and moderate race

When Trek first introduced the Émonda back in 2014, it was sort of a surprising addition. Seeming to compete directly with the Madone, the biggest difference was that Trek’s new lightweight lacked the aerodynamic touches of its sibling. Now with the most modern iteration of the Madone, we know that Trek was already working on creating …
