Vintage Shimano XTR RD-M900 MTB Rear Derailleur 8-Speed Red Medium Cage Japan
In good used condition, plenty of signs of use, but a good rider piece of kit. Spring is snappy and little to no play in the pivots. Pulleys spin freely, would probably benefit from a few drops of lube, but I’d run it as is too. Please see photos for more details.
