I replaced this Dura Ace 7300 AX derailleur on my 1983 Univega Super Strada with a fist generation Suntour Superbe.
It worked ok but I just couldn't get used to the in derailleur index system it employed. So should I keep it just so I have
everything original to the bike in case I sell it even though I'll probably never use it or try and sell it? You can see by
the photos that it is in great shape. Any idea of how much to ask for it if I sell it?
