BPW External Bearing BSA Threaded Bottom Bracket (SRAM GXP)

The BPW External Bearing BSA Threaded Bottom Bracket (SRAM GXP) is a high-quality external bearing bottom bracket designed to restore smooth, friction-free pedalling and reliable power transfer. Built for compatibility with standard SRAM GXP stepped-spindle cranksets, it uses precision-machined BSA English threads with durable forged aluminium cups for a solid, dependable installation. Outboard cartridge bearings are protected by dual-lip labyrinth seals to help keep trail dust, mud, and water at bay, while the included dynamic spacer kit helps fine-tune chainline alignment and reduce unwanted crankset play.
