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 Grail CF SLX 8 AXS or MMR Simun?

Across matched sizes, the frame front of Canyon Grail CF SLX 8 AXS is about 16 mm higher than MMR Simun. This can support a more upright starting position, while stem and spacers still affect the handlebar.
