I just got hold of this frame but have no idea what it is. Apparently it was bought unpainted from a bike shop in Italy and is Columbus tubing.
It has no serial number stamped on it anywhere so I'm a bit stuck! I've got all the info on it below and some photos.
From what I've got would anyone be able to have a stab at what grade of tubing it might be or who might have made it? It's a very long shot but there seems to be a lot of very knowledgable folk on here!
Here's the details;
Seat tube; 58cm, 28.6mm OD, 26.4mm ID top.
Top tube; 58cm, 25.4mm OD
Down tube; 64cm 28.6mm OD
Head tube; 155mm 31.7mm OD
BB; Italian
Chain stays; at BB 22.4mm, at widest point 26.7/17.4mm, at dropout 13mm
Seat stays 12mm top, 14mm middle, 11.5mm dropout
Fork blades; top 27.8/20.8mm, bottom 13mm
Seat tube angle 73.2
Head tube angle 73
