Having discovered my 'cheap out' (the polyvlant crankset offered at Velo Orange) would require more retrofitting than I have the desire or pocketbook for, I need some info on what shimano offered in their early SIS setups.
The bike is a 1991 Paramount OS
I'm running a 34/46 on the front and probably need a 13-30 or 13-32 (from harris Cyclery)
The oem 7spd sis downtube died a while back and I got a rs100 nos 8spd which would allow a buildup of a 8spd (oem is 7)wheel.
I want to keep the SIS setup but am going to need a derailleur capable of handling a 30 or 32t. large cog.
Sence I'm going to be going on a NOS hunt for something that'll work and yet offer decently crisp shifts I figured I'd get some opinions on what to be looking for.
