Force 1, BB30 CycloCross Chainset-50T-177.5mm

Product Description

The SRAM Force 1 crankset brings to cyclocross a game-changing upgrade in performance & reliability by combining the durability, simplicity, & efficiency of SRAM’s Force 22 road combined with our MTB 1x technology, X-SYNC. Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability & stronger crank construction.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. Press Fit 30 for road will require a 68mm wide shell while Press Fit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.SRAM X-SYNC 1x chain rings provide the highest level of performance & durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp & narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.
