Shimano Deore CS-M7200 HYPERGLIDE+ 12-Speed Cassette Stronger, lighter, and ready for anything. The Shimano Deore CS-M7200 brings optimized materials and refined cog tooth profiles to the 12-speed HYPERGLIDE+ drivetrain system. A mixed construction - alloy on the largest cog, steel throughout the rest - strikes the ideal balance of weight and durability. HYPERGLIDE+ cog tooth profiles keep shifting fast and smooth even under heavy load, and a wide 10-51T range makes the M7200 at home on XC race courses, enduro stages, and long all-day trail rides alike. A lighter, stronger upgrade over the previous generation. MICRO SPLINE freehub compatible.
