SRAM GX EAGLE 12 SPEED REAR DERAILLEUR

THE RANGE TO REACH. TO REALIZE. A RANGE BEYOND LIMITATION.

This new GX Eagle derailleur is the next evolution of the proven, 1x-specific X-Horizon design and answers the need for greater capacity. The larger, 14-tooth X-SYNC lower pulley allows for a 10- to 50-tooth cassette and adds to Eagle's overall smooth-pedaling feel. The new, Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. And a redesigned, robust mounting system further improves the Eagle derailleur's performance and overall durability.

Note: This derailleur is not compatible with SRAM's new 52T cassette.

Reviews

JensonUSA Journal - "Compared to the current XO1 Eagle kit that I am ridding I would say that the GX Eagle is well worth the price, the higher weight was not noticeable and the shift performance felt almost identical." - Mike Borosko

Bikeradar - "More impressive is the lack of noise and just how smooth things remain even when shifting up into the bigger sprockets where the chain angle becomes more extreme. Even when transferring the chain into the monster 50T cog, there is very little grumbling going on and I never felt like I had to totally ease off the power because things didn't feel quite right. It's impressive stuff." - Rob Weaver
