^ Wouldn't work. It's got one of those funny "aero" shaped seat tubes. It's the width needed to take a 27.2 post, but the front->back is probably twice the width and it goes to a point. I really think it'll be fine as is, though.

My problem now is - I stuck a post in there. It went in OK, though a bit snug, until about half way. Then it got stuck. I tried pulling it out and it's stuck in. I started twisting and pulling and it's slowly coming out, but completely destroying the post. It's gouging the Crap out of it and I can barely twist it out a tiny bit at a time using all my strength. I'm really glad I used a spare crap seat post. I'll have to see what's going on in that seat tube and sand it out or something. I'm hoping to take it for a ride tomorrow. I've just got to figure out that seat tube situation and throw some tires on it and I'm good to go. It even came with a computer on it, so I can see if this thing really is all that much faster than the good ol' vintage stuff. My suspicion is that it'll be Slightly faster, but not worth the harsh ride or ugly brifters and aero frame. Then this Dura-Ace stuff can go on a nice vintage frame next season with bar-ends. I gotta say, though, these spiffy new hubs are So smooth and completely effortless to turn. There's just no resistance to them, but they're still smooth as silk and axles are tight. And of course the new Dura-Ace is nicely finished and of high mechanical quality. It should make for a really nice bike on the vintage frame.

I looked it up and it's a $4,300 msrp bike and the guy who gave it to me(for Free) is a well-off customer who has several very nice newer bikes and he didn't want to deal with it since it was cracked and he's moved to Washington, but waiting to sell his house and hasn't moved his stuff yet. He "didn't want to deal with" moving this bike to Washington. I'm incredibly grateful that he gave me the bike and definitely owe the universe a Very good deed in return for this one!
