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 Cervélo R5?

The frame front of Cervélo R5 is slightly higher, by about 4.7 mm. That difference alone does not settle your position.

Canyon Aeroad CF SLX vs Cervélo R5: which bike is right for you?

Compare ride character, intended rider, geometry, and fit. Add your measurements to see which bike suits you better and which size to choose on each.

Fit verdict: the frame positions are close, a few millimetres apart. The frame alone will not decide this; use your measurements to see which size and setup gets nearer to your position on each bike.
