Increase the quality of your bicycle with the reference in ceramic bearings and a unique manufacturing quality! The CeramicSpeed ??bottom bracket is designed for frames that adopt an Italian thread type (Pinarello) with a 24mm bottom bracket.

BSA is another way of stating English threading; it comes from British Standard Cycle. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. It’s the most common threaded standard employed today. This kit works with 24mm diameter thru-axle cranks, found on Shimano, FSA, Rotor, among others.
