I have a 1980s Schwinn Super Sport that I recently took home. It had a busted 700c rear wheel with a 6-speed freewheel, so I've been looking for a replacement wheel along with a better cassette to use with those friction shifters.
This one guy offered me a Matrix wheel with a Shimano hub and 7-speed cassette attached. He told me that the cassette is a 13-30, which really is perfect for my needs, but I'm afraid the big ring will be too big for my short/medium cage Suntour derailer to handle. I have a 52/42 in the front. What's your take on this? Will I need a new derailer?
I really don't know enough about this. Anyway, thanks for the knowledge.
