The Canyon Grail CF SLX 8 eTap clearly belongs to the category of marmite gravel bikes that you either love or hate. The German bike brand makes use of SRAM’s Force eTap AXS Wide rear derailleur and offers gravel-friendly gear ratios with a 10–36 t cassette and 46/33 t chainrings. The combination of a huge gear range and small gear steps suits the bike perfectly. Another highlight is Canyon’s proprietary S15 VCLS 2.0 CF seatpost. The added comfort it provides is very noticeable and it is available with either 13 or 25 mm offset. With Canyon’s CP07 Gravelcockpit and its double-decker handlebar, the Grail CF SLX 8 eTap features a unique approach to offering additional comfort on the tops.

Due to the double-decker construction, the drops are attached to an additional cross-bar beneath the shifter levers. This creates an unusual place to rest your thumbs when riding in the drops #loveitorhateit. While the cockpit height can be adjusted by a few millimetres thanks to the spacers, that will compromise the seamless transition between the stem and frame.

Thanks to the SRAM Force eTap AXS Wide rear derailleur, Canyon’s menu offers 22 courses. Small gear steps and a wide range – excellent!
Canyon’s proprietary S15 VCSL 2.0 CF seat post offers a lot of comfort and allows you to choose between 13 or 25 mm offset. It compensates for the frame’s lack of comfort at the rear, at least when sitting.

With a maximum tire clearance of 700 x 42C, the Canyon is on the skinnier side of the spectrum. To get the most out of the bike, we recommend fitting faster rolling tires with better damping.
The CP07 Gravelcockpit offers the most comfort on the tops, but that puts the brakes out of reach. So, if you’re going to stay on the tops, you’ll just have to hold on and send it.

The large front triangle is a feast for the eyes of all bikepacking fans who want to get a custom frame bag. However, this comes at the cost of standover height.

In addition, the cockpit isn’t compatible with all aftermarket accessories. For example, if you rely on Canyon’s in-house GPS mount (not included with the bike) you’ll have a hard time attaching a handlebar bag. Lights and bells that are made to be clamped to a round handlebar won’t work here either and while changing the cockpit is technically possible, it wouldn’t make much sense as the frame is designed around these bars and you’d end up with a very aggressive position. And, after all, it’s one of the bike’s USPs. Canyon rely on a set of 700 x 40C Schwalbe G-One Bite tires fitted to a DT Swiss GRC 1400 wheelset. The frameset offers a comparatively scant maximum tire clearance of 700 x 42C. Our size M test bike weighs in at 8.22 kg and is available for € 4,779.

Like last year, the Canyon’s handling is intuitive and extremely composed with a balanced level of agility, making it suitable for gravel fans of all skill levels. Regardless of the speed you’re riding, the Grail CF SLX 8 eTap responds predictably to input from the rider. Speaking of speed, we were impressed with the gravel bike’s efficiency, both on flat terrain and in the mountains, as well as its responsive acceleration. Models like the ARC8 Eero or the S-Works Diverge are a bit livelier but the Grail will easily sprint its way into the leading pack of the test field.

The seatpost on the Canyon feels like a magic carpet ride as it absorbs small vibrations as well as larger impacts, spoiling the rider with a lot of comfort at the rear. However, we can’t say the same about the front. In terms of comfort, Canyon’s unique cockpit design only works when you’re riding on the tops. But this riding position is so upright that you’re putting minimal weight on the handlebars and it only dampens high-frequency vibrations. Unfortunately, the bars are far too stiff in all other hand positions. The comparatively low-volume Schwalbe tires don’t do much to add to the bike’s overall comfort level either. The imbalance between front and rear compliance on the Grail has a negative effect on the rider’s confidence. In the most comfortable position, the tops, you’re not ready to brake. When switching from the drops to the tops, you have to open your hands more than usual due to the crossbar that your thumbs rest on, which can also lead to fumbling in tricky situations. Apart from the cockpit peculiarities, the Canyon does instil the rider with confidence on smooth paths due to its straight-line stability, even when you’re riding fast.

Tuning tip: faster tires with better damping to round off the bike and make it more comfortable

If you mainly ride on compact gravel highways with wide, open corners and choppy asphalt roads, you will find the Canyon Grail CF SLX 8 eTap to be an efficient gravel bike at a fair price. The bike’s limited off-road performance and the lack of adjustability of the cockpit detract from its all-round capabilities. To ensure a good fit with the cockpit, you should study the geometry very carefully before buying and ideally take it for a test ride first. The latter is difficult to do with a direct to consumer bike.


  • intuitive and composed handling
  • efficient on flat terrain and carrying speed
  • comfortable seat post


  • limited cockpit adjustability and compatibility
  • imbalanced comfort
  • limited off-road capabilities
