Why We Like The SRAM XX SL Eagle AXS Transmission Rear Derailleur

The new SRAM XX SL Eagle AXS Transmission Rear Derailleur changes how we think about the connection between our cassette and derailleur. This T-Type derailleur mounts directly to our bike's rear axle and contacts the cassette directly for seemless and precise shifting performance on race day. Built specifically for high-stakes XC racing, this derailleur features a carbon cage and a Magic Wheel that keeps the pulley wheel spinning even when a stick gets lodged inside.


  • Ultralight AXS rear derailleur for SRAM Transmission systems
  • Lightweight carbon fiber design is strong and keeps weight down
  • AXS system provides instantaneous shifting at the press of a button
  • Hangerless interface shaves grams and mounts directly to the axle
  • Magic Wheel and Overload Clutch help manage chain tension for a smooth ride
  • Item #SRMD172
