SRAM GX X-Horizon 1 x 11-speed Rear Derailleur

• 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
