Thanks for the advice. I will try looking for a used wheel/freewheel first. Do I need to find a freewheel that is similar to what I have, or will any 27" wheel and 5 speed freewheel work? Or is it possible to for example, find a good wheel with say a good 6 speed freewheel and derailer and swap all of it out? I don't know what will work when swapping parts on the rear wheel/gears.
