The SRAM GX X-HORIZON rear derailleur delivers crisp and reliable 1x11 shifting on any trail. Its design reduces chain movement for faster shifts, less chain slap, and no ghost shifting. Featuring 12-tooth X-SYNC pulley wheels for secure chain control and CAGE LOCK technology for quick wheel changes, it’s built to handle aggressive riding with ease.

Technology

• 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.
  
• X-HORISON
  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.
