The 7-speed X-HORIZON rear derailleur makes shifting smooth and reliable no matter where you ride.

The 12-tooth X-SYNC pulley wheel holds the chain in place, reducing bounce and chain slap. Additionally, CAGE LOCK technology makes wheel removal and installation easier than ever.

Run silent, run deep. Shimano's ZEE rear derailleur uses a short cage and a Shadow profile to keep tucked out of the way of rocks, roots, whatever. The Plus part is a one-way clutch system that stabilizes the cage and your chain when ripping over rough terrain. Chain slap and the noise that goes with it, as well as dropped chains, are virtually eliminated. Of course, it still has the smooth action and sniper-like shifting that Shimano is rightly famous for. Freeriders and trail riders can run a typical MTB cassette like an 11-32, 11-34, or 11-36. And DHers can choose the close-ratio version and run a road cassette like 11-23, 11-25 or 11-28.
