About the Shimano SLX RD-M7100 12 Speed Derailleur

  • SLX Shadow plus 12-speed rear derailleur for the ultimate in 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
  • Rubber bumper on pulley cage for added silent drive
  • 13T pulleys and decreased derailleur tension prevent high chain tension in low gears
  • Direct cable routing prevents snagging from any trail side hazards
  • Cold forged wide alloy links and pivot body
  • Four fluorine-coated link pin bushings
  • Strong return spring for a positive shifting feel
  • Specifically designed to work with 12-speed 1x drivetrains
  • Durable sealed 13T bearing pulleys for low friction
  • Top normal spring uses the spring to select higher gears
  • Max low sprocket: 51T (1x 12-speed)
  • 41T capacity SGS cage
  • Average weight 240g

Couldn't fault the experience. Great price, fast delivery, and the bike was impeccably set up. Would 100% buy from Wheelie again.
