Engineered for smooth, reliable shifting action, the SRAM GX X-Horizon 1 x 11-speed rear derailleur puts an end to ghost shifting and reduces shift force and chain slap with its X-Horizon™ technology.

  • Features

    • X-Horizon technology features a "straight parallelogram" design that limits all movement to the horizontal axis, making ghost shifting impossible and reducing shift force
    • For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears
    • Sealed cartridge bearings and an aluminum cage offer lightweight durability
    • Cage Lock™ technology makes wheel removal and installation, as well as chain installation, faster and simpler—just push the cage forward to create slack and lock it into place
    • Roller Bearing Clutch™ eliminates derailleur bounce and chain slap without sacrificing precision
    • 12-tooth X-Sync™ pulley wheels
