About SRAM GX Eagle 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.

Comes in GX Eagle™ master colorway as part of Eagle™ Colorsystem and goes with all colors of Eagle cassettes & chains – from Black to Gold to Rainbow, to HardChrome and new Copper

Technology
X-Horizon: This 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 chainrings 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 chainrings 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. Accept no imitation.

Eagle: Eagle technology represents SRAM's 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 520%, which is equal to 2x11 drivetrains.

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

Roller Bearing Clutch: ROLLER BEARING CLUTCH technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuation: Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette.

Customer Reviews (4.7 / 5 · 3 reviews)

Riley U. ★★★★★

Shifting under power is noticeably crisper than my old setup, even on steep climbs. The updated mechanism feels solid and I haven't had a single dropped chain in two weeks of rocky trails.

Carter ★★★★★

The shifting under load is noticeably crisper compared to my old setup, and the clutch keeps the chain quiet through rough sections. It handles the grunt of climbing without hesitation, which was my main concern.

Steven X. ★★★★☆

Installed this on my trail bike and the updated cage design handles chain slap way better than the old version. Shifting is crisp and reliable, even when I'm grinding up a steep climb. Only minor nitpick is that the initial setup took a bit more fiddling than expected.
