BSA is another way of stating Englishthreading; it comes from British Standard Cycle. English threading on roadbikes mean a 68mm wide, 34mm inside diameter shell with reverse threading onthe drive side. It’s the most common threaded standard employed today. This kitworks with 24mm diameter thru-axle cranks, found on Shimano, FSA, Rotor, amongothers.
Choose between two bearings for the cups.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.
In The Box
2 threaded cups with bearings.
2 dust covers with built-in spacers.

Technical Data
English threading is easy to work with andthe drive side cup, thanks to being reverse-threaded, stays in place withoutextra effort. 24mm spindles easily fit through the shell, allow for largebearings to be employed in the outside cups.
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 Grease, All Round, and Long Lifeare greases CS designed to help the bearings roll smoothly. The first is theleast 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.
