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 backward-compatible with 10-50T cassettes for greater versatility and incremental upgrade. It's finished with the new GX Eagle master colorway to complement any cassette and chain colorway a rider wants from the Eagle Colorsystem. - Backward-compatible—works with both 10-50T and newer 10-52T cassettes - Updated cage architecture provides better chain retention and precise shifts

Of all the components that make up a mountain bike drivetrain, the shifter doesn't exactly get a lot of spotlight time. But, as the rider's literal command and control center, the GX Eagle shifter is more than worthy of recognition. With intuitive thumb actuated triggers, the positive feel gives the right rider input to make shifts crisp and discernible every time. What's more, its already legendary reliability continues for all-day epics and all-time experiences. Plus, it features an aluminum trigger that's ready for inevitable punishment, as well as MatchMakerX compatibility. Precise and durable, it's the hard-working, no-compromise shifter keeping riders in the right gear, every ride. - Aluminum trigger designed for a positive lever feel - Master GX Eagle master colorway to match all cassette and chain colors as part of Eagle Colorsystem - Matchmaker compatible
