SRAM X01 DH rear derailleur

The 7-speed X-HORIZON™ rear derailleur makes shifting smooth and reliable no matter where you ride. Engineered to maintain consistent chain gap across all seven gears, X-HORIZON™ eliminates vertical movement for faster shifting, reduced shift force and an end to ghost shifting. Our new, Type-3 ROLLER BEARING CLUTCH™ features a smoother torque curve for a quieter, more consistent operation and feel. The 12-tooth X-SYNC™ pulley wheel holds the chain in place, reducing bounce and chain slap. And CAGE LOCK™ technology makes wheel removal and installation easier than ever. Paired with the X01 DH 7-speed shifter, X-HORIZON™ forms the backbone of X-ACTUATION™ technology—and that means completely smooth shifting action.
