GS-XX-EPA-D1 With the perfect balance of robustness and weight savings, the XX Eagle AXS E-Bike transmission group has the strength to tackle long enduro days. Our new transmissions take a holistic approach to bike shifting: the entire system is synchronized, providing you with an outstanding riding experience. Shifting under load is made possible with the XX cassette through a combination of X-SYNC technology and cassette mapping, enabling seamless shifts even under the heaviest power transfer. The XX ISIS cranks are available for both Bosch and Brose systems and are based on our proven design from recent years. They come equipped with our new T-Type chainrings and include a clip-on guard. The XX Eagle Transmission Flattop chain has been specifically designed to optimize the Eagle transmission and features a unique flat top. This shape not only maximizes shifting performance and durability 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 personalized experience for all your AXS controls.
