The Shimano Deore M6200 Complete Upgrade Kit includes a rear derailleur, cassette, chain, and shifter, everything you need to build or upgrade a reliable mechanical drivetrain. The M6200 series continues Shimano's long tradition of precision and reliability in cable-actuated shifting, bringing near-XT performance and durability to a significantly more accessible price point.
