SRAM  GXP BB with Ceramic Bearings

SRAMs new hybrid Ceramic BB Bearings exceed the needs of even the most demanding riders. They offer a performance advantage over traditional bottom bracket bearings that's almost too great to believe. Besides being 10% lighter than standard bearings, ceramic bearings require an astonishing 78% less energy than the next most efficient BB on the market.

- Same compatibility as GXP units with the benefits of ceramic bearings
- Less friction, longer life span
