Chuck, you may be 100% on this. But if those tubes are crimped, I think they would show up exactly as they are in the photos. So...they may be crimped or it may just be the reflections. I'm afraid that I may have to write to Ernesto to resolve this one.

Or maybe Steven Maasland can ask him next time he talks to him - Steven, have you called him for his birthday yet?

Thanks Chuck for your input. I've revised the text to include your comments.

This photo:

shows the typical indentation in the chainstay for tire clearance and also a dark line down the center of the tube all the way back to the dropout which I am certain is not a crimping because the same dark line appears down the center of each seatstay which I am absolutely certain are not crimped.

To be brutally honest, I never really paid much attention to crimped tubed Colnagos because I thought they were a little silly from an engineering standpoint, of course only my opinion.

1981 based solely on the chainstays with the stamped "COLNAGO" in the side.
