The SRAM PressFit GXP Bottom Bracket is designed for frames with PressFit shells, offering lightweight, sealed bearings for smooth crank performance. Compatible with GXP spindle cranks and featuring simple press-fit installation, it reduces weight while providing durable, maintenance-free operation for road and MTB builds. A variant of the external bottom bracket, PressFit cuts weight and provides easier installation by allowing you to press the bearing cups into the frame instead of threading them. There's no change to the crank - spindle length and diameter remain the same.
