Shimano RD-M7100 SLX 12-speed Shadow+ SGS Rear Derailleur

Intended for use with modern 1x Shimano drivetrains, the RD-M7100 SLX 12-Speed Shadow+ SGS Rear Derailleur provides great, crisp shifts and a light action. The chain stabilising switch adds tension to prevent the chain from bouncing on rough ground and hitting the chainstays or even coming off the chainrings, ensuring that the ride is quiet and shifting remains accurate.

The 13 tooth pulley wheels have double sealed bearings for less drag and the larger circumference means less friction in the chain, saving watts and increasing speed. By using a carbon fibre outer pulley cage, weight has been saved without sacrificing the stiffness required for great shifting. The derailleur has a total capacity of 41 teeth (the difference between the smallest and largest sprocket), and a maximum low sprocket of 51 teeth so it can be happily used with single ring drivetrains without missing out on low gears.


  • Super low profile design and optimised 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 a 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
  • Full carbon fibre outer pulley cage saves weight while alloy inner cage increases rigidity
  • 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 M7100 SLX 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
  • Claimed manufacturer’s weight 240 grams
