FAQ

Which has the taller front end: Argon 18 Sum Pro or Canyon Endurace CFR Di2?

Across matched sizes the Argon 18 Sum Pro and Canyon Endurace CFR Di2 front ends are within a few millimetres of each other, so posture will depend more on cockpit setup than on the frame.

Can the same rider take different sizes on these two bikes?

Yes, and it happens often: frame labels are not standardized. Use the matched-size table for geometry, then run the fit check below with your own measurements for each bike.
