This is a chromoly frame with hi-ten sloping crown fork. 21" inch. I was hoping for a lugged frame, being that this was the first year Schwinn made mountain bikes, but this model is welded or brazed (not sure on which). Only a 10 speed setup (two crank rings, not three). The wheels have been switched out two some very inexpensive steel hub alloy rim bolt on jobs. Paint and parts look like average wear for the age of the bike. I am considering it for a drop bar conversion (though I would like a 3 ring crank instead). How much would you give for something like this? Thanks in advance.
