Optimize your bike with CeramicSpeed bottom bracket 

BSA stands for British Standard Cycle, also known as English threading. English threading on road bikes means a 68 mm width, 34 mm internal diameter with reverse threading. It is the most common threading standard used today. 

This kit is tailored to upgrade your bike with modern 30 mm crank bearings, like those from Rotor, allowing you to enjoy a more efficient riding experience.

You can choose between two types of bearings for the bottom brackets. Standard bearings have low air resistance with hardened steel races and ceramic balls. Coated bearings have the same ceramic balls in coated, hardened steel races, providing longer life and less resistance.
