CeramicSpeed BB90 bottom bracket for Trek Shimano

BB90 is the Trek oversized bottom bracket standard and is found exclusively on Trek road bikes. The shell is 90.5 mm wide and designed for use with 24 mm axles and road cranks, with the bearings housed in the shell. The CeramicSpeed bearings are supplied as two bearings which are then pressed into the frame.

These two bearings consist of either CeramicSpeed standard or coated bearings. Both feature super smooth, super round CeramicSpeed balls in hardened steel rings. The coated version has a metallic coating on the rings, making them even smoother and harder, resulting in lower friction resistance and longer lifespan.
