Riders want the derailleur to do its job shifting on command whether under climbing load or the stage finish. The GX Eagle(TM) 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.
