Canyon's brand new Endurace CF SLX 9.0 SL is a complete revamp of the original, and succeeds in offering a wonderfully smooth and comfortable ride yet with fast and engaging handling to indulge all those who like to ride quickly. And it now benefits from hydraulic disc brakes and thru-axles for improved braking performance in all conditions.
The endurance bike is the most in-demand style of road bike at the moment and that means it's the most crowded category, with every manufacturer offering a bike that is in principle a relaxed and more comfortable version of a race bike. That helps explain why our buyer's guide to endurance bikes is one of our most-read articles.
This is a review of the range-topping £5,099 Endurace CF SLX 9.0 SL, but the complete range starts at £2,999, using the same frame and common details like hydraulic disc brakes and 28mm wide tyres, so you can get much of the performance and comfort of our test bike for a good deal less. Even at these prices, the Canyon direct-sales business model means these are extremely competitive compared with similarly specced bikes from other big brands.
You can read all the technical details of the new bike in this first look article. With a Shimano Dura-Ace Di2 groupset, lightweight Mavic wheels, carbon handlebar and exceedingly comfortable Fizik saddle, the medium sized Endurace CF SLX weighs 7.3 (16lb), putting it up there with the lightest disc brake-equipped road bikes we've tested, regardless of their category designation. That lack of weight provides very little penalty on the climbs or anytime you're applying maximum power.
Ride and performance
There's no denying it, the Endurace CF SLX is hugely impressive in terms of ride and performance. It's the smoothness that first grabs you. The VCLS 2.0 seatpost provides a huge range of rearward deflection at the saddle – you can actually see the saddle moving underneath you when you look between your legs. It's slightly disconcerting at first (especially coming from the razor sharp Pinarello Dogma F8) but you quickly get used to it. It works well, filtering out vibrations from poorly surfaced roads while also dealing with bigger impacts such as potholes or cattle grids.
The comfort factor is helped by the fact that Canyon has lowered the seat clamp inside the frame. Lots lower. It basically allows more of the seatpost to flex back and forth, ramping up the available deflection. It feels every bit as effective as the Isospeed decoupler on Trek's Domane, which I reviewed a while ago. Adjusting the saddle angle is a bit of a fiddle – you have to remove the post from the frame – but it's a set-and-forget job. Adjusting the saddle height is made easy with height markers on the front of the post and an Allen bolt at the back.
At the front of the bike is the distinctive one-piece carbon fibre handlebar. Canyon calls it the H31 Ergocockpit, though I prefer hammerhead because it resembles the head of a hammerhead shark when you're looking down at it. It has obviously been designed to reduce the frontal surface area and therefore drag, but it's also been tuned to provide more compliance (6% according to Canyon) than the H11 Aerocockpit it's based on. It appears to work.
It might look like a big immovable chunk of carbon, but it does seem to provide enough compliance that it helps damp quite a lot of the roughness that would normally be transmitted through the fork and into the handlebar and leading to a jarring ride. With this bar, only the biggest impacts really unsettle the otherwise buttery smooth ride.
The downside is that you can't adjust the position as easily as with a conventional setup, but Canyon does alter the length of the stem based on the frame size, so it's not a big job to change it. I found the stock bar just fine, but I'm sure Canyon would happily swap it if you knew you needed a longer stem.
The aero-shaped tops with their six-degree back sweep are very comfortable to grip, but I reckon the drops could be a bit shallower for the sort of person who is likely to buy this bike.
Tyres and wheels
Contributing to the bike's overall smoothness are the 28mm wide Mavic Yksion Pro tyres, standard across the range and not just on this top model. At 80psi they provide plenty of cushioning and predictable traction in a range of conditions. I found them dependable in the rain and dry, and over rough and gravel surfaces.
The new Mavic Ksyrium Pro Carbon SL Disc wheels have a wide rim to really make the most of the wide tyres. They provide all the stiffness and ruggedness you need, with thru-axle compatible hubs. At 1,520g for the pair they're very light for a disc brake-ready wheelset, and certainly contribute to the Endurace's agility. The new Instant Drive 360 freehub engages very quickly and makes the nicest sound, a few notches down in the decibel meter than a Hope freehub I'd say.
Racy yet relaxed
Canyon bills itself as a race bike company, so it's no surprise that the Endurace CF SLX is one of the raciest endurance bikes I've tested. All endurance bikes are relaxed in comparison to the race bikes they're loosely based on, some more so than others, but the Endurace is really not that high at the front. The stack is only 10mm higher than the Ultimate CF SLX race bike. That means it's a bit more laid-back, but you can still get quite an aggressive position if you prefer to really hunch over the bar and get aero to punch as small a hole through the air as possible.
Although the Endurace's geometry is more relaxed than the Ultimate's, it's more agile and nimble than many rival endurance bikes. Its short 990mm wheelbase gives it a nimbleness that's lacking in some, while the increased fork rake used to decrease the trail (the distance from the centre of the contact point of the front wheel with the road to the point where the steering axis intersects the road surface) further contributes to the direct and agile manners it displays in willing hands.
It's absolutely stable when you want it to be, though, such as riding no hands to unwrap an energy bar. There's also no lack of stiffness in the frame and fork. Slack this bike ain't.
I found the position a really good fit. It's not quite as slammed as a race bike but I could still get pretty low over the front – but not so low that you're in danger of putting your back out. The reach is also shorter. Combined, I found the fit pretty much spot on; I could happily ride the Endurace CF SLX in place of my race bike on faster training rides and chain gangs, yet it was comfortable for all-day rides. Heck, I'd happily race it if the rules allowed it; I found very little compromise.
On a day-to-day basis, the Endurace CF SLX is a simply wonderful bike. I've ridden it nearly every day since it arrived, using it for leisurely rides through the countryside to faster-paced sessions with a power meter, and there's not one wrinkle in its handling that blemishes the package. It's near perfect. It tackles rough country lanes, fast and smooth main roads, fast, swooping descents, tortuous climbs, congested roads, even the odd gravel track, all with a level of refinement few of its rivals can better.
If there's one criticism, it's the lack of mudguard mounts. That's deliberate on Canyon's part, as it already offers the Inflite for people who want a disc-equipped bike that can be fitted with mudguards, leaving the Endurace focused on performance rather than any year-round versatility ambitions. Regardless, it'll be seen as an omission by mudguard enthusiasts, especially as there looks to be plenty of space between the tyres and frame, and when other endurance bikes, such as the Trek Domane and Cervélo C5, have included mudguard eyelets.
Brakes and bits
Endurance bikes benefit from disc brakes for all-weather riding, with confident braking in the wet and dry their biggest asset. Shimano's Dura-Ace Di2 groupset with hydraulic callipers operating on 160mm rotors sets the benchmark at the moment. It's a marvellous thing. The brake levers are easy to operate with just one finger even on the very steepest hills, with plenty of modulation plus grip from the tyres meaning no risk of locking a wheel, even on rain-soaked roads.
It uses the latest flat mount standard to bolt the callipers to the frame and fork, which provides a nice appearance but does lack the adjustability of a post mount setup. Brake squeal and noise were a rare occurrence during the test period.
Canyon has given the Endurace 12mm thru-axles at both ends, with a clean Allen bolt head that does away with a fixed QR lever, marginally reducing weight but massively improving the appearance. You can either carry the supplied QR lever or just take a multi-tool with a 5mm tool bit.
As I said at the start of this review, the market for endurance bikes is pretty crowded at the moment, so there's plenty of choice for anyone seeking a fast and comfortable bike for long rides. The Cannondale Synapse and Giant Defy Advanced SL are two brilliant bikes that have long been established at the top of the category; the Cervélo C5 and Trek Domane, two new releases this year, are also both excellent. But the Endurace CF SLX? The ride, comfort, smoothness and performance is every bit as good as its key rivals, but factor in the price and the Canyon could be the best new endurance bike to be released this year.

Use this box to explain your score
Based on the performance alone the bike is an easy 9/10, it does everything you want an endurance bike to do and more, with its aero shaped tubes and low slung geometry. Then you add in the price and there's no denying it, the value is impressive compared with similarly priced endurance bikes in terms of the level of equipment on offer here. It's nearly perfect. If I'm being really fussy, the lack of mudguard mounts counts against it, especially as both the Cervélo C5 and Trek Domane manage to offer this provision.
