SRAM GX Eagle 12 Speed Rear Derailleur - Lunar SW Only 37 in x 24 TPI)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, its also backwards compatible for the 10 50t versions. Giving riders choice, because thats how it should be. Further proof that the GX Eagle derailleur is there for one thing to do the job.
