Thanks the the rplys. Ohjohnnybegoods, your Puch sure is pretty. I would like to get a NR grouppo, but it looks as if that won't fit my budget (unless someone has a grouppo on the cheap they would let go, hehe). I figured a 105 group since I have/had a few pieces laying around (rear derailleur, headest). I have some campy stuff as well, but not at the level of NR. Does anyone know how to clean surface rust without damaging/scuffing the paint. Also, where should I start with a bottom bracket, and any idea of threading?
