Shimano Deore M5100 Shadow plus 11-speed rear derailleur for dependable shifting performance and durability. Shadow plus features a super low profile design and optimized slant angle for super light shifting action. Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting. Single tension spring prevents contact with the chainstay resulting in a silent ride. 13T pulleys and decreased derailleur tension prevent high chain tension in low gears. Direct cable routing prevents snagging from any trail side hazards. Wide alloy links and pivot body. Fluorine-coated link pin bushings. Strong return spring for a positive shifting feel. Durable 13T bearing pulleys for low friction. Top normal spring uses the spring to select higher gears. Max low sprocket: 51T (1x 11-speed). 40T capacity SGS cage.
