Developed for maximum chain control, each tooth’s thickness is precisely CNC machined to support the chain’s inner & outer links perfectly. Eight available X-SYNC™ Direct Mount chainrings (26-28-30-32-34-36-38-40) let you tune your gear range to match your terrain, wheel size & riding style. Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability & stronger crank construction. With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 & X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail & enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" & 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs & Rock Shox forks.GXP’s Gutter Seal design cuts friction & weight—improving both feel & performance A variant of the external GXP bottom bracket, Press Fit cuts weight by up to 40 grams & eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length & diameter. This is a new design led by SRAM. It’s all the best from BB30 & Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with Press Fit 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. Press Fit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. ...
