Shimano XT 9 sp Shadow Rear Defailleur

Derailleur is mid-cage length. It is in excellent condition. It has been used for 2 seasons and has been cleaned and re-lubed after almost every ride. De-greased, washed, air-blasted dry and then re-lube all points with Tri-Flow. (Yes, I know that's anal but I don't like wearing out drivetrain stuff!)
It has never been bent or damaged in any way. All pivots are free of play and actions are very smooth.

If yours is worn or if you want a spare 9 speed derailleur I think this is a good deal.
