Ah, thank you. I will check the link.

I built up the bike with all the parts I had around: Mavic cosmos wheel set, Dura Ace brakes, cassette and chain, Ultegra 9 speed deraillieur (1x9 drive), Sugino Mighty Competition cranks, MKS pedals and clips, Cinelli 1A stem, unknown manufacturer "Made in Great Britain" bars, cheap, funky Chinese (?) brake lever and a Tiagra brifter, Campy seat post and a Sella An-Atomica saddle and an inexpensive Velo Orange headset.

It rides great and doesn't look too shabby. It's smooth, comfortable, solid and responsive. Right off the bat a much better ride than the early 90s Cannondale that I've been commuting on the last four months. Quite happy!

What tubing did the ADs have? I bought the frame on eBay advertised as "early 1980s Columbus steel road frame". I have no idea if it is indeed Columbus. Or Reynolds. Or whatever. The only sure thing is the Gipiemme drop outs.

Whatever kind of steel it is Im digging it and feel ok having paid $100 for the frameset. Plus another $30 for cables and housing...

Thanks to everyone for all of the information, suggestions, links and wisdom!
