SHIMANO DEORE XT Rear Derailleur RD-M8100-GS 12-speed

Shimano Deore XT RD-M8100-GS Rear Derailleur

A 12-speed Deore XT rear derailleur with a short GS cage for 10-45T HYPERGLIDE+ cassettes. The shorter cage gives more ground clearance (Shimano say 28mm more than the SGS) and plays nicely with rear suspension movement.

SHIMANO SHADOW RD+ keeps the chain stable on rough ground. A bumper on the pulley cage and bigger 13T pulleys keep the drivetrain quiet. Not sure it fits your bike? Talk to us and we'll check.
