Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The GX Eagle™ derailleur gets it done with an updated cage architecture that improves chain management.

Refined to work with the new 10-52t cassettes, it’s also backwards compatible for the 10-50t versions. Giving riders choice, because that’s how it should be. Further proof that the GX Eagle™ derailleur is there for one thing - to do the job.


  • Revised cage architecture for optimum chain guidance
  • Swift, direct shifting operations
  • Derailleur pulley bearings made of steel
  • Easy mounting of chain and rear wheel thanks to Cage Lock™
  • Colour-coordinated with Eagle components
