The headset has Campy engraved on it, and although the components are mix-and-match, the group seems to be primarily Nuovo Record; whether this is relevant or not, I don't know. Wondering if anyone can help, or if there is a simple answer... In the end, I suppose I could pull the stem out and measure, but when you're talking mm, I wouldn't want to screw up.

thanks!
