SRAM GX Eagle Type 3 X-HORIZON Rear Derailleur 12-speed

Simply put, the new GX Eagle™ derailleur extends the range of your riding because of its ability to handle the 10-50t Eagle™ cassette—but there’s more to this new derailleur than capacity. The GX Eagle™ derailleur includes the Type-3 ROLLER BEARING CLUTCH™, so that chain management feels the same on every cassette cog, small or large. And a new Eagle™ pulley design, combined with the SRAM Eagle™ chain, helps to make this drivetrain super quiet and incredibly efficient.

Best-in-class chain management with the proven X-HORIZON™ design and Type-3 ROLLER BEARING CLUTCH™ technology.
Simplified installation and added robustness with SRAMs repositioned CAGE LOCK™.
Best-in-class 1x efficiency and quiet operation with the Eagle™ pulley technology.
The GX Eagle™ derailleur carries with it the rough-and-tumble toughness of our X-HORIZON™ design; no derailleur wants to be abused, but the X-HORIZON™ design is built to withstand a lot.

SRAM GX Eagle Trigger Shifter 12-speed
The GX Eagle™ trigger shifter is the control center of the new Eagle™ drivetrain that unlocks its range to allow you to realize full potential of Eagle™. Superior ergonomics and adjustability let you shift quickly, comfortably and intuitively. The GX Eagle™ shifter carries with it all of the enhancements and improvements that the XX1 and X01 Eagle™ trigger shifters received, improving trigger feel, precision and durability for every rider on any terrain.

Eagle™ provides the smoothest and most reliable 1x shifting in mountain biking.
Optimized shifting precision via X-ACTUATION™ cable pull works flawlessly with Eagle™ rear derailleurs.
Super durable forged aluminum trigger is designed to take a beating.
With MatchMaker™ X you can adjust your shift, brake and Reverb lever setup for lever ergonomics that are perfect for your hand position and the way you ride.

Increased longevity and better chain guiding with the allnew Eagle™ PowerLock® chain connector with FLOW LINK™ technology.
Unique features and design also provide significantly improved wear resistance on Eagle™ cassettes and rings.
The GX Eagle™ chain is constructed using the same link geometry and general manufacturing processes as XX1 and X01 Eagle™ chains, making it the ideal backup chain for XX1 and X01
