BSA30 Bottom BracketBSA comes from British Standard Cycle, aka English threading. English threading on road bikes means a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. Its the most common threaded standard employed today. This kit allows you to fit 30mm thru axle cranks, like those from Rotor, to fit in the tight space of this 34mm spindle. Choose between two bearings for the cups. Standard Bearings have low drag thanks to hardened steel
