From: Hervey Bay, Qld, Australia.
Bikes: Colnago (82, 85, 89, 90, 91, 96, 03), 85 Cinelli, 90 Rossin, 83 Alan, 82 Bianchi, 78 Fountain, 2 x Pinarello, Malvern Star (37), Hillman (70's), 80's Beretto Lo-Pro Track, 80's Kenevans Lo-Pro, Columbus Max (95), DeGrandi (80's) Track.
I have an '85 Supercorsa that is built out of Columbus SPX. It's seat tube is 585mm c to c and the top tube is 575mm c to c. Interestingly, the seat tube angle is 74 degrees while the head tube angle is 75 1/2 degrees.
I think its build geometry make it a good criterium frame. It is quite twitchy to ride with little flex at the BB. Built-up with Campy Super Record (Ti BB and pedals) it weighs in at 21 1/2 lb. which I think is quite light for its vintage and SPX tubing.
