Shimano’s Deore M6000 MTB rear derailleur brings you features that are borrowed from its top-end XTR series, but not at a top-end price point. This means you’ll enjoy outstanding drivetrain performance as you’re attacking climbs and cranking up to speed on the flats.Thanks to its clutch system, this mech allows you to push yourself hard on the roughest trails, without worrying about chain slap or drop. It also delivers ultra-quick, quiet shifts and with its fluorine-coated bushings, shifting requires minimal rider effort.
