SRAM saw the opportunity to make a better press fit system where all the best from BB30 and PressFit bottom brackets would be combined into one captivating package. PressFit 30 features an integrated seal pre-assembled into the cups to further prolong bearing life. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. This bottom bracket is designed for 30mm spindle cranksets. Advantages are huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction and simple installation. Also allows for larger diameter frame tubes increasing frame stiffness.
