Ceramicspeed BSA BB中軸 (Sram GXP Road)

The BSA, or English threaded, bottombracket is a traditional shell size. It has an inner diameter of 34mm and is68mm wide. These cups thread into the BSA shell making it possible to installSRAM and Quarq 24/22mm spindle cranks.

The CeramicSpeed kit comes with bearingspressed into threaded cups, which are then threaded into the frame. Thosebearings consist of either CeramicSpeed Standard or Coated Bearings. Supersmooth, super round CeramicSpeed balls are rotating in hardened-steel races inboth. The Coated version has a metallic coating laid onto the races, making iteven smoother and harder, resulting in longer life and lower drag.

Technical Data

The cups come with bearings installed and asleeve is included to further seal the system from the elements and fromrubbing on internal cables.

The Standard Bearings have only 0.3-.04watts of frictional drag per set, an average drag reduction of 75% compared tostock bottom brackets. This is the result of superior design includinghardened-steel races, and ceramic balls that are 100% smoother and 15% harderthan the ceramic competition. They also last 3x longer.

Coated Bearings last even longer andfeature even lower drag. Life is boosted by 60% and drag plummets by 50%compared to our Standard.

All Round Grease is used in the bearings.It can be replaced for lower drag Race Day Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messyconditions.
