The new XX SL Eagle AXS Transmission group represents the pinnacle of Cross Country performance. The XX SL Transmission is an evolution of the XX Eagle AXS, used by world champions and World Cup winners. It has been designed to meet the needs of the most demanding riders in the lightest configuration. The new XX SL Eagle Transmission derailleur is more robust thanks to our no-hanger interface and features well-known technologies such as our Overload Clutch and the AXS coupling process. The new XX SL Transmission cassette is one of the main reasons why Eagle Transmission offers the best shifting performance under load. Thanks to its X-SYNC design, it shifts better the harder you pedal. In addition to the X-SYNC technology and the newly designed gear gradation, it is also our lightest Eagle cassette. The XX SL Transmission cranks remain the lightest ISO-certified cranks on the market and feature the remarkable new XX SL Eagle Transmission (T-Type) Direct-Mount chainring, which ensures maximum stiffness. The XX SL Eagle Transmission Flattop chain has been specifically developed to optimize the Eagle Transmission and features a unique flat top. This shape not only maximizes shifting performance and robustness but also gives your superbike a contemporary look. The AXS Pod Ultimate features a "Click and Fire" design with two buttons, transforming every command from the rider into a much more personal experience for all your AXS controls.
