- Check before you buywarning · Front RotorFront rotor: 203mm exceeds the fork max of 200mm. A post-mount adapter is the part that steps a caliper up to a bigger rotor, sold in the maker’s own discrete size steps (commonly +20mm, e.g. 160 to 180mm or 180 to 200mm) rather than for any gap - and not every step is offered for every caliper model, so check the maker’s own fitment before buying. On 40 of the 177 verified rotors in this catalog. Applies to all 13 variants.
