The XX Eagle Transmission AXS groupset offers the perfect balance between durability and weight savings, providing the strength needed for big enduro days while keeping the weight manageable. SRAM’s all-new Transmission groupsets take a holistic approach to shifting, with the entire system synchronized for a superior ride experience. Shifting under load is made possible on the XX cassette thanks to a combination of X-SYNC technology and cassette mapping, allowing for seamless shifts even during the most intense power output. The XX carbon cranks feature SRAM's new T-Type rings and include a clip on guard. Engineered to optimize Eagle Transmission, the XX Eagle Transmission Flattop chain features a unique flat top, maximizing shifting performance and durability while modernizing the look of your bike. The AXS Pod Ultimate controller offers a personalized experience for all AXS controls, with a "click and fire" two-button design that transforms rider inputs into a more intuitive and responsive experience. With the XX AXS Transmission groupset, you'll have a complete system that offers seamless shifting, durability, and weight savings for the most demanding trails.
