The PressFit BB86 bottom bracket for GXP cranks

The SRAM bottom bracket for frames with BB86 bottom bracket shells and SRAM Truvativ GXP cranksets. These bottom brackets are only compatible with SRAM and Truvativ GXP cranksets

Truvativ’s external bottom bracket for cranks with an integrated axle. Other systems rely on lateral load to adjust the bearing play. However, this leads to premature wear of the bearings. GXP works differently: the left bearing is clamped between the bottom bracket axle and the left crank arm. The right bearing remains axially free to move on the bottom bracket axle; the bearings do not need to be subjected to lateral load during adjustment. The GXP system uses two special precision ball bearings and a total of eight seals.
