SRAM GX Rear Derailleur, 1x11 Speed - Black


SKU: 175590

The SRAM GX 1x11 rear derailleur features all of the same technology as the more expensive X1 models with the only difference being the aluminium construction which results in a slightly heavier weight and a more wallet friendly price tag!

This SRAM Rear Derailleur is crafted from lightweight, stiff and durable aluminium, resulting in a feather-light weight with bombproof durability. Kitted out with X-Horizon and Roller Bearing Clutch technology, this derailleur produces super-fast exact shifting at all times. This derailleur excels in muddy conditions with mud-shedding capabilities provided by the 12-tooth X-Sync pulley wheels to keep you riding smooth even when the ground isn’t.

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.


Developed specifically for SRAM 1X, X-ACTUATION keeps shifting sharp and consistent across the entire 10-to 42-tooth cassette.


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.
