The wheels I picked up a few weeks back are fine, with an 8 speed cassette.

The wheels came with 700x32 tires, but they were just a bit too wide for the chainstays on this old bike, and too tall for the fork crown, so I settled on 28s, which I already had on hand.
My old wheels were very much an old 6 speed freewheel.

I will try my old crankset, but sure the spacing might be too wide. Also, still curious about Shimano specific cables or are generics fine for shifting?
When I was working on my Trek 950, the freehub had a 7 speed cassette on it. Tried an 8 speed, but couldn't get the lockring on. Which is why I am hoping the 10 speed and 8 speed cassettes are interchangeable on this newer wheelset.
