Shimano M986 XTR 10-Speed Shadow Plus Rear Derailleur: The XTR Shadow Plus Dyna-Sys 10-speed rear derailleur is the ultimate in shifting performance & durability. It also features a super low profile design that reduces the risk of damage from trail side hazards. The Shadow Plus rear derailleur uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive & shifting (this can be switched off to remove the wheel). Single tension spring prevents contact with the chainstay resulting in a silent ride Direct cable routing prevents snagging from any trail side hazards Full carbon fibre outer pulley cage saves weight while alloy inner cage increases rigidity Cold forged wide alloy links & pivot body leads to lower weight while increasing rigidity Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails Strong return spring for a positive shifting feel enhanced cable pull ratio provides a more accurate shift action making the system less proneto contamination & trail chatter Dyna-Sys 10-speed compatible only Durable sealed bearing pulleys for low friction Top normal spring uses the spring to select higher gears 35T capacity GS cage
