The X0 Eagle AXS E-Bike Transmission groupset is SRAMs most robust high-performance transmission. The T-TypeTransmissions take a holistic approach to a bicycle shifting, an entire system synchronized, providing you with a superior ride experience. Shifting under load is made possible on the X0 cassette due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The X0 Flattop Transmission chain features a Dark Polar finish specific to X0, has been plated with electroless nickel, and comes with a PVD coating for unbelievable resistance to corrosion and wear. Fully approved for E-MTB use with solid pins. Featuring a click and fire two-button design, The AXS Pod Ultimate controller transforms the crucial act of rider inputs into a vastly more personal experience for all your AXS controls.
