SRAM X1 Type 2.1 11sp Rear Derailleur 00.7518.070.000

- X-Actuation ratio specifically engineered for SRAM's 1x11-speed mountain drivetrain\n- 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\n- Type-2 (T2): 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\n- 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\n- Forged aluminum links, B-knuckle, and inner cage with an aluminum outer cage
