I wonder why they kept the longer stays...if they had a specific handling/geometry reason for that size frame, or if it's simply because they could then use a similar rear triangle carbon mold as the other frame sizes.
Yes I can see that is possible problem down the road if the 650B rim sized doesn't make the inroad into the road market as it has the MTB market. I suspect Canyon uses a similar carbon mold as I have rad that Giant is the frame maker for Canyon. It appears that if you look at other Canyon cycles the same occurs in there respective XS frame sizes...... chain stays similar lengths to their 700c brethren.
