I was running a 6-Spd. Suntour New Winner freewheel on my 1982 road bike. Then went to an IRD 7-Spd. freewheel. Now new wheels with a Campy hub and an 8-Spd. Miche cassette - and all of these with a 1982 Campy downtube friction-shifters. I wouldn't even consider an indexed system for this fine piece of perfection. Nope. Uh uh.
