I am trying to figure out the size of a bike I picked up 2 weeks ago at a yard sale. I don't have a metric ruler, so I apologize for that. But here are some measurements... and I do believe that I am measuring it all center to center.
Bianchi Bravo. Black Frame.
Downtube has this information. Bianchi / campione / del mondo / 1986 - 1987 / Colorado Springs
Bottom Bracket has IS760576
Top tube: 21.5"
Down tube: ~24.4"
?Vertical tube: 21.5"
It has Shimano 105...
Im thinking its somewhere in the 59-61 range, but I want to narrow it down.
