SRAM's PressFit bottom bracket design is a variant of the external bottom bracket. Instead of threading bearing cups into a frame, the bearing cups are simply pressed into the frame. With PressFit, there is no change to the crank - the spindle length and diameter remain the same.
With PressFit you get the weight and strength advantages of BB30 and the simplicity of PressFit technology. The key difference between PressFit and BB30 is how the bearings are fitted into the frame. PressFit bearings are housed in nylon cups, which are simply pressed into the frame’s bottom bracket shell. There are no snap rings required! No more spacers or wavy washers! The PressFit GXP system is designed for Truvativ GXP spindle cranksets and requires a 41mm inner diameter bottom bracket shell 86mm or 92mm or 89,5mm case width. Advantages of the bottom bracket system are the lighter weight, greater bearing durability and stiffness, easier installation and adjustment
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.
