Shimano XTR Rear Derailleur 10sp M985

For the ultimate in shifting performance and durability. Shadow technology features a super low profile design that reduces the risk of damage from trail side hazards, and 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.
