I've owned a Romani frameset built with Columbus Zeta tubing since 1982, but probably it was built the previous year as I bought it unused second hand. I know it was the entry level (elegant way to describe "low end") tubeset of Columbus at the time. According to the decal, it is cold drawn. It takes a 27 seat post and is plain gauge 1 mm. Is it the same steel alloy as the Aelle series that came later?
