SRAM RD X01 DH 10S T2.1 Medium Cage Rear Derailleur - 10 Speed

The 10-speed X-HORIZON™ rear derailleur makes shifting smooth and reliable no matter where you ride. Engineered to maintain consistent chain gap across all ten gears, X-HORIZON™ eliminates vertical movement for faster shifting, reduced shift force and an end to ghost shifting. ROLLER BEARING CLUTCH™ technology and the 12-tooth X-SYNC™ pulley wheels hold the chain in place, reducing bounce and chain slap. And CAGE LOCK™ technology makes wheel removal and installation easier than ever. Paired with the X0 10-speed shifter, X-HORIZON™ forms the backbone of EXACT ACTUATION™ technology—and that means completely smooth shifting action.
•X-HORIZON™ technology provides more responsive shifting and eliminates ghost shifting, a common problem on DH bikes
•Two cage lengths for various applications, including abnormally long chain stay growth
•EXACT ACTUATION™ variant allows upgrades to existing bikes in the aftermarket
