Check before you buy
- Check before you buywarning · Rear RotorRear rotor: 203mm exceeds the frame max of 180mm. 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.
