Built for performance, the Shimano XT RD-M786 SGS 10-Speed rear derailleur delivers mountain-ready toughness, responsive shifting and a low-profile design to minimize exposure.


  • Shadow-type design features a lower-profile body and bracket with direct cable routing and a stabilizer switch to avoid obstacle contact and minimize chain slap
  • Wide link parallelogram design increases rigidity for excellent, responsive shifting performance; stronger return spring ensures fast, snappy shifts
  • Lightweight aluminum construction; coated link pivot bushings minimize friction for fast, responsive movement
  • Shimano XT RD-M786 SGS 10-Speed rear derailleur handles a minimum cassette cog size of 11T and maximum cassette cog size of 36T
  • Please note: derailleur is compatible with Shimano Dyna-Sys HG-X 10-speed mountain cassettes and chains (sold separately)
