Shimano Deore RD-M7200 12-Speed Long Cage Rear Derailleur XT-Inspired technology. Deore durability. The Shimano Deore RD-M7200 carries forward all the technology of the Deore XT M8200 in a more durable long-cage package. A steel pulley cage adds extra strength over the XT's design - trading a small amount of weight for a measurably more robust structure that holds up to the demands of trail and enduro riding. SHADOW ES chain stabilization keeps the chain from bouncing off on rough terrain, while a wedge-shaped low-profile body is designed to dodge impacts rather than absorb them head-on. Long cage construction is compatible with the full HYPERGLIDE+ 10-51T 12-speed cassette range. Pair it with a DEORE M6200 shifter and HYPERGLIDE+ cassette for a fast, reliable, hard-wearing drivetrain that covers any trail. Features SHADOW ES chain stabilization a slimmer, stronger evolution of Shimano's pioneering SHADOW concept with a wide link structure for improved durability and chain retention Steel pulley cage adds extra strength and durability over the XT M8200's cage design at nominal weight cost Wedge-shaped low-profile body moves out of the way on trail impacts for worry-free riding Long cage compatible with HYPERGLIDE+ 10-51T 12-speed cassettes for maximum gear range SPECIFICATIONSModel RD-M7200-SGSSeries Deore M7200Speeds12-Speed Actuation Mechanical (Cable)Cage Length Long (SGS)Pulley Cage Material Steel Chain Stabilizer SHADOW ESMax Cassette Size51T (HYPERGLIDE+ 10-51T) | Shimano | Deore Rd-M7200 12S Derailleur Sgs Long Cage (10-51T)
