Front post/post brake mount to accommodate 203mm rotors. Shimano Part Number: ISMMAF203PPA
To help understand Shimano adapters, we have broken down 'F203-PP'
- The 'F' denotes front mount.
- 203 refers to the size of the rotor it is designed for.
- PP stands for two things. The 1st 'P' means it is a post-mount calibre and the 2nd is for a post-mount fork.
If you are upgrading to a 203mm rotor, please check with your fork manufacturer. 203mm exceeds the safe limits of some forks and could cause damage.
