CeramicSpeed BB ALPHA Bottom Bracket for BSA Shimano Road | BSA threaded 68mm - 24mm
The CeramicSpeed BB ALPHA for BSA Shimano Road is a high-performance bottom bracket designed to last longer than your frame. Intended for use on road bikes with a 68 mm BSA/English threaded bottom bracket shell, this bottom bracket allows fitting cranksets with a 24 mm spindle such as Shimano or other compatible brands.

The structure is completed by custom seals, precision dust covers, and a new spacer tube configuration, which together with the lightened cups offer faster installation and a 10% weight reduction compared to the previous generation.
