Bottom Brackets and Bearing Cups for Bike Drivetrains

This range of integrated bottom bracket cups covers most current road and MTB standards: PressFit / PF30 / BB30 / BB86-92 / BB386 / BSA. Depending on the reference, they are compatible with 24 mm (Shimano, FSA, Rotor), 24-22 mm (SRAM GXP), 28.99 mm (SRAM DUB), or 30 mm spindles. Several Blackbearing and Tripeak models feature ceramic bearings to reduce friction and increase lifespan, and some versions come with a mounting tool. There are also threaded BSC/BSA 1.37x24 or Italian 36x24 cups for Shimano, SRAM/Truvativ, Campagnolo Ultra Torque / Pro-Tech / Ekar cranksets, as well as adapters allowing conversion from a Ø46 shell to a threaded bottom bracket or reducing a 30 mm spindle to 24 mm or 24-22 mm. An ideal solution for the workshop or for modernizing a frame while keeping its crankset, available on PSB Cycle Parts.
