The SRAM GX Eagle Rear Derailleur is built for riders who demand reliable, precise shifting on every trail. Designed for modern 1x drivetrains, it works seamlessly with wide-range Eagle cassettes, giving you the low climbing gears and high-speed range needed for aggressive trail, enduro, and all-mountain riding. Its robust construction is made to handle rough terrain, rock strikes, and daily use, while still delivering crisp, consistent gear changes under load.
Featuring SRAM’s proven clutch and cage design, the GX Eagle rear derailleur keeps your chain stable and quiet, even on the roughest descents. The narrow-wide pulley profile improves chain retention and reduces dropped chains, so you can focus on the ride instead of your drivetrain. Whether you are upgrading an existing bike or completing a new build, this derailleur offers a great balance of performance, durability, and value, making it a favorite choice for mountain bikers who want dependable shifting without the premium price tag.
