Front post/post brake mount to accommodate 180mm rotors.
To help understand Shimano adapters, we have broken down 'F180-PP'
- The 'F' denotes front mount.
- 180 refers to the size of the rotor it is designed for.
- PP stands for two things. The 1st 'P' means it is for a post-mount calibre and the 2nd is for a post-mount fork.
