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.

Please visit the SRAM UDH Bike Finder to ensure that your bike is compatible with this SRAM Eagle Transmission groupset.
