SRAM XX1 X-Horizon Rear 11-Speed Carbon Derailleur Black

With its "horizontal parallelogram" design and pulley offset, X-HORIZON™ keeps the chain gap constant across all 11 gears, providing fast, precise shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting. ROLLER BEARING CLUTCH™ technology reduces bounce and chain slap. CAGE LOCK™ technology makes wheel removal and installation easier than ever before.

Paired with the XX1 shifter, the X-HORIZON™ rear derailleur forms the backbone of X-ACTUATION™ technology for unbelievably smooth shifting action.

Key Highlights Are
X-HORIZON™ design reduces shift force, ghost shifting and chain slap
12-tooth X-SYNC™ pulley wheels
Large upper pulley offset automatically adjusts chain gap
Ceramic bearings
