KACTUS Bicycle Bottom Bracket with SKF Ceramic Bearings (BSA24 / BSA DUB / BSA30 / PF4124)

The bottom bracket (BB) connects the bicycle frame to the crankset; different frames and cranksets require specific BB types.

We currently stock high-end ceramic bottom brackets from KACTUS, featuring premium SKF bearings. Ceramic bearings already deliver superior spin and durability, and with SKF technology, the smoothness and rolling performance are second to none.
