Choose between two bearings for the cups. 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.
In The Box
- 2 threaded cups with bearings.
- 2 dust covers with built-in spacers.
- Spacer tube.

- Sticker sheet.
English threading is easy to work with and the drive side cup, thanks to being reverse-threaded, stays in place without extra effort. 24mm spindles easily fit through the shell, allow for large bearings to be employed in the outside cups.
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.
Race Day Grease, All Round, and Long Life are greases CS designed to help the bearings roll smoothly. The first is the least drag, the last is the most durable. All Round comes in road bearings, Long Life in MTB. You can change the grease to tune performance.
