Shift cable housing ferrules
We recommend unsealed shift cable housing ferrules for noticeably lower operating forces, based on our workshop experience. Sealed ferrules, such as sealed Shimano SP40/SP41 types, can add friction and are therefore not recommended for this setup.
For the HIBOX P1, please use the separate P1 installation manual.
