Sram GX Eagle X-Horizon Type 3 12S 10-52 rear derailleur

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 backwards 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 compliment 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.

Technologies

Eagle™
Eagle™ technology represents the newest 1x drivetrain technology. Eagle™ is a lighter, simpler, more durable, and easier to use drivetrain. Eagle™ features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle™ technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.

X-Actuation™
Developed specifically for Sram 1x™, X-Actuation™ keeps shifting sharp and consistent across the entire cassette.

Cage Lock
With Cage Lock™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

Roller Bearing Clutch
Roller Bearing Clutch™ rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With Roller bearing clutch™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

X-Horizon
The X-Horizon™ rear derailleur's "straight parallelogram" design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

X-Sync
Sram X-Sync™ 1x chain rings provide the highest level of performance and durability. The Sram X-Sync™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync™ rings are an integral part of the Sram 1x™ drivetrain
