BSA comes from Birmingham Small Arms, aka English threading. English threading on mountain bikes means a 73mm-wide, 34mm-inside-diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit allows you to fit 30mm cranks, like those from Rotor or RaceFace, to fit in the tight space of this 30mm spindle.

CeramicSpeed Coated Bearings are hand-built with unique CeramicSpeed Ceramic Balls installed on coated, hardened-steel races for longer life and less bearing drag compared to standard bearings.
