I've got an old SS that I was told(previously repainted) is a Murray hanging in the storage unit. I've also got a set of aluminum MTB wheels with 9 speed set-up that would make the bike lighter and more versatile. Would it be safe to spread it far enough to fit those wheels? MTB spacing is 135mm. Otherwise maybe I could re-lace the rim onto a 9sp road hub if 135mm is too far but 130mm would be OK. It would probably make a really cool little 1x9 town cruiser/grocery getter if I can figure out the crank situation.
If it helps answer the question at all, my bike looks pretty much like this, but without the tank or racks.
