Bottom bracket designed for fat bikes, only compatible with PressFit bottom brackets with an internal diameter of 41 mm and a width of 92 to 121 mm.
A variation on the external bottom bracket, PressFit reduces the overall weight by 40 grams and offers simplified installation by allowing you to press the bearing cups into the frame instead of threading them on. No changes are made to the crankset; the length and diameter of the axle remain the same (24 mm GXP axle). Only compatible with Sram or Truvativ GXP cranksets!
