The BSA derives from the British Standard Cycle. The English threading on road bicycles indicates a shell width of 68 mm, an internal diameter of 34 mm, with reverse threading on the crankset side. It is the most common standard with threading used today.

This kit is compatible with cranksets of 24 mm diameter, found among others in Shimano, FSA, Rotor. Thanks to Ceramic bearings, this bottom bracket operates with minimal resistance and friction.
