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

Yes. Frame labels are not standardized, so the same rider may need different sizes. This comparison deliberately avoids a generic matched-size answer and hands your measurements to Bike Fit instead.

Which frame has the higher front: Canyon Aeroad CF SLX or Colnago V4?

Across matched sizes, the frame fronts of Canyon Aeroad CF SLX and Colnago V4 differ by only a few millimetres. Stem and spacer choices will have more effect on handlebar position.
