If you're going to ride Magnesium you gotta go Pinarello. 2009 - the last year of the magnesium Dogmas. They did make a few w/mag stays, too, but this was standard.

I don't have an as-built pic, but it's sporting Campy 10s Ergo Record/Chorus with Bora wheels. Not exactly C&V.
I pull it out when I'm riding some ugly hills or longer rides.
It rides nice, but mostly just laughs at me - "Is this all you've got?"
