Hello everyone, I have a 2025 Canyon Grail CF SL 7. The bike came stock with the DT SWISS Gravel LN wheelset. I upgraded to the ZIPP 303 XPLR S.
According to Canyon the bike has a maximum tire clearance of 42mm, which is definitely true in the rear but not in the front. The frame measures at the chainstay 54mm and at the fork 64mm.
After going trough the tire compatibility chart from Sram I decided for the Goodyear Zipp XPLR Inter tires, because they are one of the few that measure less in reality then on paper, when combined with this wheelset. Most tires measure 2-3mm wider. The 45mm tire in the rear fits perfectly and I have no worries of it rubing against the frame. In the front I fitted the 50mm version and it also fits with a comfortable amount of room to the fork.
The Pirelli Cinturato tires where also a consideration. Solid pair of tires.
I am not to sure about fitting 2,1" tires in the front. I might try that next season
I wish manufacturers would put out more data about the actual width of tires on wheelsets with different inner widths.
I hope this post will help someone in their choice for frame/wheels/tires.

Canyon seems to be more conservative. Specialized for example says 50mm tire clearance but in the same sentence will say that 2,2 inch MTB tires will fit too. So roughly 55mm.
My Ridley says 53mm “actual tire width” and 50mm tires mounted tubeless on some 32mm internal width Elite Aero Gravel wheels come out to 51mm.
How the heck does a 45mm tires measures 32mm wide?? Or am I stupid and can’t read this caliper (that I hate it’s numered in cm not mm… )
On the back 42 mm, on the front you can go higher.
That looks pretty tight. I would line the inside of the fork and triangle with some tape or vynil (ride wrap) and watch for wear marks after a few rides. If it’s rubbing or ripping the tape substantially, swap them out.
It’s a crack on the fork?
Sorry, that’s way too narrow in the front. If you can push the rim to the side and the tire contacts the fork, you’ll eventually cut into the carbon
Hey. I own a Canyon Experience Partner store. 45mm front and 42mm rear is our recommendation. You can fit a bigger tyre in the front but that does not mean you should. 6mm clearance all around the tyre is good for mud, stones etc if you don’t want to damage the frame.
