The X-HORIZON 7-speed rear derailleur makes shifting smooth and reliable, no matter where you ride. Designed to maintain a consistent chain gap across all seven gears, X-HORIZON eliminates vertical movement for faster shifting, reduced shifting force and an end to ghost shifting. Our new Type 3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, smoother 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 removing and installing the wheel easier than ever.
