Ceramicspeed BSA BB中軸 (Campy UT)

English threading is the most commonthreaded bottom bracket standard these days and having a fast Campagnolo bottombracket to fit it is the only way to get a Campy Ultra-Torque to mate. Englishthreading the common name for BSA; the B standing for British. The shell is68mm wide, the inner diameter 34mm, with the threading reversed on the driveside.

Choose between two bearings for the crank.Standard Bearings have low drag thanks to hardened-steel races and our Ceramicballs. 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 andeasy to service. The only bit of complexity is installing the bearings, whichsit on the spindles. A removal/installation tool is necessary; we sell onehere, but any appropriate tool will work.

Put more of your energy into forward motionby reducing frictional drag wherever you can. CS Standard Bearings typicallyhave 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% smootherand 15% harder than ceramic competition. The bearings last at least 3x longerthan other bearings.

Race Day, All Round, and Long Life aregreases CS designed to help the bearings roll smoothly. The first is the lowestdrag; the last is the most durable. All Round comes in road bearings, is abalance between low drag and high durability. You can tune performance bychanging grease.
