SRAM recognizes that riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The SRAM GX EAGLE Rear Derailleur - 52T Max gets it done with an updated cage architecture that improves chain management. It has been refined to work with the new 10-52t cassettes and is also backwards compatible for the 10-50t versions, so you got options! The updated cage architecture provides better chain retention and precise shifts for a smoother riding experience. It’s finished off with the new GX Eagle colorway that compliments and cassette and chain from the Eagle colorsystem.


Backwards compatible works with both 10-50t and new 10-52t cassettes.

Updated cage architecture provides better chain retention and precise shifts.

Comes in GX Eagle™ master colorway as part of Eagle™ Colorsystem and goes with all colors of Eagle cassettes & chains from Black to Gold to Rainbow, to HardChrome and new Copper.
