Deore XT 11 Speed Mech RD-M8000

The best balance of price vs function for 11 speed drivetrains. If you're running 1x11 or 2x11, you almost certainly want the medium cage (GS) version.

• Deore XT Shadow+ Dyna-Sys11 11-speed rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design.
• Shadow+ features a super low profile design that reduces the risk of damage from trail side hazards.
• The Shadow + chain stabilizer tension can easily be adjusted externally via a hex key.
• Shadow + is Shimano's name for what we call a clutch, Shadow + uses a chain stabilising switch that when on will reduce chain bounce in rough terrain,  maintaining more stable drive and shifting. This can be switched off to remove the wheel.
