Well not necessarily, picked up at the Goodwill drop off. Guy on duty wasn't going to take because of "rust" on the rims. I was looking a the cosmetic appearance and it looked in pretty good shape. When I got it home discovered the positronic drivetrain. Quite a novelty with the freewheel crank. Somewhere along the line a new Shimano Tourney rear derailer was slapped on it. Will this setup work or was there something special about the original derailer for this oddity?
