For 1x11 MTB gearing configurations
Weight: 220 g.
With its "horizontal parallelogram" design and pulley offset, the SRAM XX1 11-speed Rear Derailleur keeps the chain gap constant across all 11 gears, providing fast, precise shifts. By limiting all movement to the horizontal axis, X-HORIZON technology is faster, reducing shift force and eliminating ghost shifting. ROLLER BEARING clutch technology reduces bounce and chain slap. Type 2 clutch and Cage Lock technologies makes wheel removal and installation easier than ever before. Just as on the chainring, X-Sync tooth design of pulley wheels active holds onto chain. Paired with the XX1 shifter, the X-HORIZON RD forms the backbone of X-Actuation technology for unbelievably smooth shifting action. Compatible only with XX1 Grip shift or Trigger Shifter.
