Is anyone running a 4iii Precision on their Canyon Ultimate?
It looks like it might not fit due to the gap between crank and chain stay.
I have tried the Frame Compatibility test and the AAA only slides part of the way of the clearance guide on my Canyon Ultimate CF SLX 8.0 rim brake bike.
I have it on my disk frame. It fits just ok. Once got some dirt in between which scratched the frame. I would put a little plastic protector foil there.
