So I just picked up this Bianchi off of CL for relatively cheap, at least I think so as it is missing the rear wheel. Can anyone help me identify the model? The sticker at the bottom of the seat tube says it was manufactured in January 1981. Campy NR Pat 80 rear derailleur, campy FD/DT shifters/levers/brakes/seatpost, gipiemme dual sprint crank and hub.
