This cup and bearing set allows standard SRAM and TruVativ cranksets to be used on frames that have 86.5mm wide (BB86) unthreaded BB shells with 41mm inside diameter.
A variant of the external bottom bracket, PressFit cut weight by up to 40 grams and provides 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.
• Same compatibility as GXP units with the benefits of ceramic bearings
• SRAM, Shimano and FSA offer “press-fit” style bottom brackets. Shimano and FSA label their compatible bottom bracket as “BB86(Road)” and “BB91(MTB)”
• Less friction, longer life span
• 83 grams
