SRAM GX Eagle Rear Derailleur 12 Speed, Lunar

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 12 Speed, Lunar 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 for the 10-50t versions. Giving riders choice, because that’s how it should be. Finished with the new GX Eagle™ master colorway – to complement any cassette and chain colorway a rider wants from the Eagle™ Colorsystem. Further proof that the GX Eagle™ derailleur is there for one thing - to do the job.

The SRAM X-SYNC 2 Eagle is the next step in the evolution of the SRAM X-SYNC technology. The aggressive teeth design improves chain retention, resulting in a smoother, more efficient pedal feel. The X-SYNC 2 Eagle design, with a focus on long wear-life, reduces friction and the accumulation of mud, grit, and grime.
