SRAM's GXP Blackbox Ceramic Bottom Bracket features ceramic bearing technology, making it one the smoothest, most efficient bottom brackets on the market. In addition to being lighter than standard bearings, SRAM's ceramic bearings use a more rounded cut to reduce mechanical drag and create optimal power transfer. Also, these durable ceramic bearings are more resistant to moisture and dirt, which means this bottom bracket will perform season after season. The GXP Blackbox Ceramic Bottom Bracket has alloy cups, anodized in Red, and is designed to work with all SRAM road cranksets.
