Sram engineers don't rest on their laurels. So when they found a way to make the lightest and stiffest crank even lighter, they did it. A new process further shaves grams off the hollow carbon arms and to keep up with current fit trends they've added the first 160mm carbon crank length option. Paired with a 1x aero chainring, this crankset is ready to help you break PRs. SRAM's X-SYNC™ 1x chainring ensures maximum performance and durability. The long edges of the SRAM X-SYNC™ teeth grip the chain before traditional triangular teeth. The narrow, sharp tooth profile and the rounded, sloping edges support the chain guide. To offer the best possible performance even on muddy terrain, the X-SYNC™ chainrings are equipped with grooves to remove dirt and mud from the internal chain links and rollers.
