Reviving this thread to post the latest conversion: an '87 Trek 330 Elance, which I bought as a frameset plus a few original parts for relatively small money on eBay auction. It's got a reasonably high BB and reasonably short-reach for the original 700c wheelset, so it was a good conversion candidate. The tires are Pacenti PariMotos, which measure about 38mm wide, just narrow enough for the rear stays. Parts include Weinmann/Rigida Zac19 rims on old Dura Ace hubs, SunTour Cyclone II mechs, Stronglight 86bcd crankset with 48/36t rings and MKS touring pedals, SunTour 7-speed indexed bar-end shifters, Sugino seat post and Brooks Flyer saddle, Nitto stem and no-name Rando bars, Tektro brake levers and DiaCompe 750 centerpull brakes. The battleship grey finish is in pretty good shape if a bit ordinary. I'm hoping the yellow bar tape dresses it up a bit.
