Ceramic Speed BB ALPHA Bottom Bracket for BSA Shimano Road Threaded

CeramicSpeed BB ALPHA Bottom Bracket for BSA Shimano Road | Threaded BSA 68mm - 24mm

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

Thanks to the use of grade 3 Silicon Nitride ceramic balls combined with hardened stainless steel cages, this bottom bracket ensures ultra-low friction and exceptional moisture resistance — up to 500% more protection compared to traditional models.

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

All CeramicSpeed BB ALPHA bottom brackets come with a lifetime guarantee, confirming their quality and durability over time.
