Built with quiet operation and a smooth ride in mind, the SRAM X01 DH 7-Speed Rear Derailleur keeps us shifting with ease no matter the terrain. It features X-HORIZON technology to eliminate vertical movement and ghost shifting, while the Type-3 ROLLER BEARING CLUTCH creates a quiet and consistent feel during our ride. Pair it with the X01 DH 7-speed shifter for an unreal level of smooth, consistent shifting.
