Leveraging the legendary history of SRAM shifting, the GX 1x11 rear derailleur provides incredible shifting speed and precision.

X-Actuation technology eliminates slop and shifting variation. Roller Bearing Clutch technology delivers maximum drivetrain stability - even through the most punishing terrain. And with Cage Lock technology, wheel removal and installation are easier than ever.

Technologies

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

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-X-Sync chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-X-Sync rings are an integral part of the SRAM 1x drivetrain.
