SRAM Pressfit GXP BB

 SRAM GXP pressfit bottom brackets for 86mm road and 92mm mtb shells with 41mm ID.  For stepped 24/22mm SRAM / Truvativ crank axles.

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.

Weight : 83g Ceramic,  94g Standard
