Tech Talk: Canyon Endurace CF SLX 9.0

Anyone who’s considering buying this bike probably already knows two things: Canyon has a reputation for cost-effective excellence, but it has struggled to fulfill delivery orders recently. As the name implies, this is a bike for endurance cyclists, those who want to ride long distances or in a more relaxed style outside competition. So it’s more for the gran fondo riders, sportive enthusiasts and weekend warriors among us rather than the race rig.  At the same time, though, the new model has gone a step forward compared to its predecessors and it’s presented as something more than a normal endurance bike: a bike that could go far, but also fast with a high level of responsiveness and control. By retaining some of the key features of the Aeroad and the Ultimate, the new Canyon Endurace CF SLX is trying to fill the gap between the 100 per cent sportive models and the race machines.

Aerodynamic frame 

Comparison Result

In order to make the Endurace CF SLX more aerodynamic than the former model, Canyon focused on the components that are more exposed to the wind, like the down tube. Compared to the 2014 version, the new tube looks ‘less fat’ on the top and has got a more oval shape to cut the wind. Tested in the wind tunnel, the difference between the Canyon Endurace CF SLX and the Ultimate CF SLX Disc Prototype are very tight, with the Endurace being just 1.4 watts slower than its racier cousin. Once more, if compared to the Ultimate, the Endurace features a 10mm higher stack and a 8mm shorter reach.

Aerodynamic Cockpit

As on the Aeroad CF SLX, the Canyon Endurace CF SLX features an integrated carbon stem and handlebars. This is the new H31 Ergocockpit, which is claimed to be 24g lighter and 10 per cent more vertically compliant than the H11 Aerocockpit. The increased surface area created by the aero-style bars actually spreads the load on your palms, and road shocks felt better dissipated as a result.The clamp system has been completely redesigned, the stem is pressed into the shaft with two screws and a transition plate for a more balanced distribution of the force.

Disc brakes and wide tyres 

Canyon opted to equip the Endurace with the standard Shimano, flat mount hydraulic disc brakes. All the bikes’ sizes (except for the XXS which mounts 140 mm rotors) will mount 160 mm rotors on the front and on the back.  To match and reap the benefits of the disc brakes, the Canyon Endurace CF SLX is equipped with 28mm tyres, but both frame and forks have clearance to take up to 33mm tyres. Even though this tyre proved its comfort and performance even over unpaved roads, its rolling resistance on the flat will never be the same as a tyre conceived for pure speed. The forks had to be reinforced in order to sustain the higher brakes loads due to the disc brakes As the Endurace has disc brakes, the fork has had to be reinforced so it is able to deal with heavier braking loads (especially on the left side). The new fork is consequently heavier than the former one, and it comes in at 325g, 30g more than the fork used for the Ultimate CF SLX. 

Flexible seatpost

Another feature Canyon developed on the Endurace to make the bike more comfortable is a flexible seatpost. The VCLS 2.0 seatpost that Canyon used for the new Endurace CF SLX is claimed to have more flex compared to the first version, but at the same time a kink halfway up the seat tube designed to keep the rider positioned over the bottom bracket and not behind it. The seat clamp is also a new feature in the Endurace conceived for giving you more flex and comfort. First appearing on the Ultimate CF SLX, the clamp is moved from its position at the top of the seat tube to a place 110mm lower down inside the seat tube. Above this point the seatpost sits in a rubber sleeve to seal it off from dirt and water ingress and prevent it from rattling, while crucially giving the post room to bend rearwards.


Gran Fondo: The Gran Fondo is Italian mean "big ride". Is a type of long-distance road bicycle race, in which riders are individually chip timed and have the right of way at all intersections. 

Sportive: A cyclosportive is characterised by being a mass participation cycling event. In several countries, including the UK and Australia and parts of the USA, they're billed as non-competitive events. However in Europe in particular, there is more of a competitive element with categories and prizes awarded to the fastest finishers. Most, if not all, sportives use timing chips ensuring a healthy level of competitiveness is always present no matter what. Results are usually published in detail on the event website and often have gold, silver or bronze time standards.

Stack: Stack is the vertical distance, in centimeters, from the center of the frame’s bottom bracket/crank to the top middle point of the head tube (where the fork passes through the frame).


Ride On!
