Sram GX Eagle 12-Speed Rear Derailleur

Riders desire optimal performance from their derailleur, whether they're climbing or reaching the finish line. The GX Eagle derailleur excels in this regard with an enhanced cage design that enhances chain control. It has been refined to work seamlessly with the new 10-52t cassettes, while remaining compatible with the 10-50t versions. This flexibility allows riders to choose according to their preferences. The GX Eagle derailleur also boasts the new GX Eagle signature colorway, which complements any cassette and chain color from the Eagle Colorsystem. This serves as further evidence that the GX Eagle derailleur is dedicated to its primary purpose: getting the job done.

Featuring Cage Lock technology, the rear derailleur facilitates quicker and simpler wheel and chain installation. By pushing the cage forward and securing it in place, slack is created, enabling easy manipulation.

The Roller Bearing Clutch technology eliminates any unwanted bouncing or slapping of the derailleur and chain, all while maintaining precision.

Developed specifically for Sram 1x, X-Actuation ensures precise and consistent shifting throughout the entire cassette.

The "straight parallelogram" design of this rear derailleur restricts movement solely to the horizontal axis, effectively preventing ghost shifting and reducing the force required for shifting. The large upper pulley offset design guarantees rapid and precise gear changes by maintaining a consistent chain gap across all gears.

Sram X-Sync 1x chainrings deliver exceptional performance and durability. Their tall square teeth engage the chain earlier than conventional triangular teeth, while the sharp and narrow tooth profile, along with rounded chamfer edges, effectively manage a deflected chain. To enhance performance in muddy conditions, the X-Sync chainrings feature mud-clearing recesses for the inner chain links and rollers. Developed in Germany, X-Sync rings are an integral part of the Sram 1x drivetrain, unrivaled by any imitations.

Eagle technology represents the latest advancement in 1x drivetrain technology. It offers a lighter, simpler, more durable, and user-friendly solution. The Eagle system incorporates all-new 1x components, engineered to deliver enhanced durability and performance while maintaining a significant weight advantage over other drivetrain options. Moreover, Eagle technology provides an expanded gear range of 520%, equivalent to that of 2x11 drivetrains.
