This bottom bracket features nearly zero loss of power due to friction, thanks to the bearings. Either our Standard or Coated Bearings. Both have super round, super smooth CeramicSpeed balls rolling on hardened-steel races. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag. They come installed in cups.

The bottom bracket is already stiff thanks to hard ceramic bearings and hardened-steel races. Thanks to CeramicSpeed, its also nearly zero drag. Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. Thats in the range of a 75% drag reduction versus conventional bbs. The bearings last at least 3x longer than other bearings.
Change the grease for your rides. TT and Track, All Round, and LongLife are greases CS designed. The first is the least drag, the last is the most durable. All Round, in the middle, comes in road bearings.
