Bolt-In BB (to match gearbox mounts)
Want to swap in between your gearbox and a standard drivetrain and optimise you BB drop? Our bolt in BB matches a standard gearbox frames mounting pattern (Pinion, Effigear, etc). The BB bore is located in the same location as the gearbox so geo is 100% preserved, or you can choose a custom BB drop.
CNC machined from 7075-T6 for use with BSA BB bearings (bearings not included).
