It's hard to tell from the pics I saw but the bike in question appears to be from the 1980's. Most 70's Italian bikes did not have braze ons for a water bottle on the seat tube. Also the seat post is an aero design and the brakes are not period correct for the 70's. If the derailleur cables go under the bottom bracket rather than the typical above bracket Campy braze ons, I think you can assume that this is an 80's bike. I would love to have that tandem or even the track bike though! Cheers, Keith Kessel
