GXP® Bottom Bracket


Gutter Seal Technology drastically improves sealing against the elements while reducing seal drag. A new standard in external bearing performance.

  • Gutter Seal Technology
  • Improved tool engagement
  • Sealed cartridge bearings
  • English thread



A variant of the external bottom bracket, PressFit cut weight by up to 40 grams and provide easier installation by allowing you to press the bearing cups into the frame instead of threading them. There's no change to the crank — spindle length and diameter remain the same.
