I have an old colnago?? frame that I want to build up but am not sure what I have.
There is a sticker on it that says Columbus tubing if that helps.
Anyway, I really don't care about the tubing. I'm really interested in getting a compatible bottom bracket and maybe a new headset. I'm assuming its an italian 70mm bb?? can anyone confirm this? How can I be sure its a colnago?

An Italian BB shell will measure 70mm in width

I've never seen a Colnago with anything but an Italian bb.

Is the OP sure it is a Colnago though?
I read it as him/her not knowing it was the aforementioned piece of italian two-wheeled porn brought down from the heavens by God himself and blessed by the Pope.

A few seconds with a metric ruler should answer the question. :)
If you are sure it's a Colnago I'm sure the threading is Italian.
