Looking to meet the demands of the most extreme enduro riders, SRAM presents the X0 AXS Transmission groupset, its toughest and most high-performance drivetrain system to date. The all-new Transmission system takes a comprehensive approach to shifting by synchronizing the entire system to provide an unparalleled ride experience. The X0 cassette, with its X-SYNC technology and cassette mapping, allows for seamless shifts even when under the heaviest load. The X0 Transmission DUB crankset is a remarkable all-aluminum design that perfectly balances stiffness and weight, making it one of the lightest aluminum cranksets available. The new Transmission Flattop Transmission chain features a Dark Polar finish specific to X0 and comes with a PVD coating for unbeatable resistance to wear and corrosion, making it fully approved for E-MTB use with solid pins. For more rugged terrain, the X0 rings are compatible with removable bash guard(s). The AXS Pod ultimate controller, with its "click and fire" two-button design, transforms the rider's input into a highly personal experience for all AXS controls.
