SRAM GXP Bottom Bracket

Solid bearing technology for your SRAM/Truvativ cranks: the GXP bottom bracket by SRAM Truvativ
GXP is different - and better. Other systems rely on side-loaded bearings to eliminate play, causing bearing wear. GXP captures the left-side bearing between the spindle and the left crankarm and allows the drive-side bearing to float axially on the spindle. There's no need to side-load bearings during adjustment. No excess wear. And a much simpler installation.
