Ceramicspeed - BSA for Campy UT

English threading is the most common threaded bottom bracket standard these days and having a fast Campagnolo bottom bracket to fit it is the only way to get a Campy Ultra-Torque to mate. English threading the common name for BSA; the B standing for British. The shell is 68mm wide, the inner diameter 34mm, with the threading reversed on the drive side.

Choose between two bearings for the crank. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag.

Technical data

English threading is easy to install and easy to service. The only bit of complexity is installing the bearings, which sit on the spindles. A removal/installation tool is necessary; we sell one here, but any appropriate tool will work.

Put more of your energy into forward motion by reducing frictional drag wherever you can. CS Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. CS balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings.

TT and Track, All Round, and LongLife are greases CS designed to help the bearings roll smoothly. The first is the lowest drag; the last is the most durable. All Round comes in road bearings, is a balance between low drag and high durability. You can tune performance by changing grease.
