Hi all, I have a patent '84 NR rear derailleur for sale. It's overhauled and ready to go. Nearly perfect with the exception of slight abrasions on the upper and lower pivot arms from being layed over or scrapped. These are imperceptible from a foot away, that's how slight they are. Email me if you want to see a photo of this derailleur. $75.00 shipped.
