SRAM GXP Road

The CeramicSpeed kit comes with bearings pressed into threaded cups, which are then threaded into the frame. Those bearings consist of either CeramicSpeed Standard or Coated Bearings. Super smooth, super round CeramicSpeed balls are rotating in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in longer life and lower drag.
