CeramicSpeed BSA Bottom Bracket MTB - Black

Bottom brackets with English threads are referred to as BSA; the abbreviation stands for British Standard Cycle. The English thread on MTBs means a 73 mm wide shell with a 34 mm inner diameter and reverse thread on the drive side. It is currently the most commonly used thread standard. This set works with cranks with a 24 mm axle diameter, as offered by Shimano, FSA, Rotor, and others.

CeramicSpeed bearings are pressed into the cups. The coated bearing has CeramicSpeed balls that run on a 3-micrometer thick coating on hardened steel rings – for greater durability and lower friction.
