The bottom bracket is a lowly component item, literally and figuratively. It resides in the nexus of road grit and moisture that is the down tube/seat tube/chainstay juncture. Before you forget about this bottom bracket, know this. The SRAM GXP Italian Bottom Bracket relies on precision ground steel balls and races tucked away inside sealed cartridge bearings. It's designed to spin freely and provide season after season of smooth service.

SRAM's bottom brackets, while interchangeable between all SRAM and Truvativ cranksets, are brand specific -- meaning, they can only be installed with SRAM cranks. The key element that makes them different from a Shimano or FSA bottom bracket is that the left side bearing has a smaller diameter to mate with the stepped spindle of the SRAM crank. This design allows the inner race of the left side bearing to be captured between the crankarm and the spindle, effectively locating the crank. The right side bearing "floats" on the spindle handling only radial loads as you pedal. The SRAM design optimizes bearing load, minimizes drag, and gives you greater durability.

The SRAM GXP Italian Bottom Bracket has alloy cups and is threaded for 70mm Italian bottom bracket shells.
