SRAM's GX Eagle line is designed to save weight, be more efficient and provide optimal longevity for drivetrain components. The GX Eagle Rear Derailleur can accommodate SRAM's 10-50T cassette, for an effortless pedaling feel. The Type-3 Roller Bearing Clutch delivers a smoother torque curve for a quieter and more consistent operation and feel and Cage Lock has also been added further back in the derailleur to protect it from trail debris. This new robust mounting system furthers the innovation of the Eagle derailleur's performance and overall durability.


  • Cage Lock is faster and simpler
  • Roller Bearing Clutch delivers maximum drivetrain stability
  • X-Actuation keeps shifting sharp and consistent across the entire cassette
  • X-Horizon limits all movement to the horizontal axis, making ghost shifting impossible while also reducing shift force
