CeramicSpeed BB90 bottom bracket bearings Trek SRAM GXP, Black
Trek developed its own bottom bracket standard to optimize frame construction. BB90 has a 90.5mm shell width and a 37mm inner diameter and is designed so that the outer bearing cups can be hidden in the frame. The CeramicSpeed kit comes as two bearings, which are then pressed into the frame. These two bearings consist of either CeramicSpeed Standard or Coated Bearings. Both are equipped with super smooth, super round CeramicSpeed balls that rotate in hardened steel races. The Coated version has a race coated metal layer, making it even smoother and harder, resulting in longer lifespan and lower resistance. In the box: 1 x BB90 bearing 24mm 1 x BB90 bearing 22mm for GXP 2 x seals 1 x integrated dust cover 24mm 1 x metal dust cover GXP Wave washer + spacers All Round Grease Decal
