So your current wheel(s) are damaged, and you want to replace them. Easily and economically?

I copied this from some other thread. It's a rec from another. New set of 700c wheels that use a freewheel, not cassette. They are 130mm for the rear, so would require you spread the frame a little.
I'd suggest print it out and take it to a bike shop and ask if they can get them or if they have something like that.
