Shimano XTR M986 Shadow Plus Rear Derailleur

Shimano's M986 XTR Shadow Plus rear derailleur is a game changer. The innovative Shadow Plus rear derailleur allows you to virtually lock out the pulley cage using increased tension to eliminating chain throw, chain slap, and extraneous drivetrain noise -- in other words the drivetrain issues you have while riding rough trails at high speed. The built in On/Off switch and included adjustment tool allow you to customize pulley cage tension and also help facilitate removal of the rear wheel. Combine that with the unobtrusive Shadow derailleur profile, improved cable pull ratio and sealed top and bottom pulleys and you get the paragon of all-mountain derailleurs.

  • Shadow Plus technology: low profile/chain tensioning
  • Cage features carbon outer plate with aluminum inner plate
  • Stiff return spring and revised cable pull for consistent, positive shifting feel
  • Sealed bearing pulleys
  • Medium or Long Cage options available

Most techs will tell you the newer chain retention rear derailleurs require a slightly longer chain (an extra link compared to tradition rear derailleurs). You can browse our entire selection of chains and chain accessories here.

I think they used the "pinnacle" down in the description somewhere. Yes, this is the top of all derailleurs. Does anyone disagree?

The best 10sp derailleur - Apr 11, 2015

This is an awesome derailleur. The clutch really quiets the drivetrain. I run it with a large 40T cog.

This derailleur muted my drivetrain and I swear it kept me from dropping the chain. Did I mention it's light too? I almost gave it 4 stars 'cause I had to skip lunch for a month to afford it. Yeah, it's expensive but it still gets 5 stars.
