Check before you buy
- Check before you buywarning · Front RotorFront rotor: 220mm exceeds the fork max of 203mm. 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 15 of the 177 verified rotors in this catalog. Applies to 4 of 6 variants.
