SRAM GX 1x11sp Rear Derailleur

- X-Actuation ratio specifically engineered for SRAM's 1x11-speed mountain drivetrain- X-Horizon design aligns the parallelogram to a horizontal axis providing constant chain gap across all 11 gears resulting in fast, precise shifts with reduced shifter force- Type-2.1 (T2.1): self lubricating, roller bearing clutch mechanism provides one-way friction damping to cage improving chain stability and reducing chain-slap/noise, with an incorporated CageLock feature for faster wheel changes and chain service- X-Sync 12-tooth pulley design reduces noise and maximizes chain control by alternating wide/narrow teeth to mirror chain profile, while upper pulley offset maintains chain gap to cassette Primary Color - Black Cage - Long RD Weight - 265g Speed - 11 Maximum Cog - 42T Minimum Cog - 10T
