This is a used Shimano Deore XT RD-M732 rear mech from the late 1980s.
It is the long cage version for 3 x 7 speed drivetrains.
It has a few cosmetic marks and some dirt in the hard to reach parts.
The teeth of the top jockey are a bit worn and the bottom jockey bearings are wobbly.
It is in otherwise good working order. The pivots move freely with no play.
In very good overall condition, especially considering it is approx. 35 years old.
Thanks very much for looking. Please check out my ebay shop for loads more bike stuff.
