Bottom brackets designed for performance and reliability

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