HSC's external, threaded bottom brackets are equipped with high quality ceramic bearings for superior smoothness, better performance, and longer life than manufacturers' stock bottom brackets. The aluminum bearing cups are forged and CNC machined, then anodized in a plethora of colors.
These bottom brackets are available for either English (BSA/ISO) or Italian threaded frame shells, with options for Shimano's 24 mm Hollowtech II cranksets, or SRAM's stepped 24/22 mm GXP cranksets.
HSC Bottom Brackets may be installed using any Hollowtech II compatible tool, such as the Park Tool BBT-9 .
