Why height alone is not enough
Riders with the same height can need different sizes because inseam, torso length, flexibility, and preferred handling differ.
Roubaix is an endurance road bike, so compare comfort posture and reach rather than copying a race-bike size.
If you are between sizes, start from the size that gives safe standover and a sustainable reach.
Compare before buying
Use nearby model comparisons when a label does not translate cleanly across brands.
