Hi all, I am looking to replace the rear derailleur on my 1985 lotus excelle. It has the standard long-cage shimano 600EX. It was working fine until someone whacked into it while chained to a bike rack and broke off the fitting where the limit screws exist. So i'm missing the piece of metal with that fitting on it now. (part of it anyway)
Soooo, I already have a new Shimano cassette hub on the rear rim (which I built myself) so I'm using a 9 speed cassette now. So I thought maybe just upgrade the derailleur as well? Any recommendations? Maybe a compatible dura ace or something? Key is that I have a 11-30T cassette on there now, So I need something can handle that 30.
