Several years ago I was given a 1983 or 1984 Columbine road bike that had been built up with the Campy 50 year anniversary group. It had been ridden very little by the previous owner (knee problems) and it is so nice and unblemished that I am almost afraid to ride the thing. Aside from having the original sew-up wheels relaced into a modern clincher setup, I've done nothing to the bike. It is beautiful! Does anyone have much background information on these Columbines? The frame is a work of art... Thanks!
