I love the curved top tube design. I almost picked up a really old 
Pinarello funny bike a few years ago with a similar design, but the 
seller wouldn't budge on the price ($900, a bit much for something that 
would see little more use than wall art).

I need to correct myself though, It isn't a Takara funny bike my friend 
has, it's a Nashbar. Websearch shows it as a Nashbar Aero Sprint Pursuit 
possibly made Shogun. My friend thinks it was made by Takara, though 
anytime anyone asked him who made the frame he would reply "Takara....I 
think".

Here it is as I raced it in  ~1992:

Yes, the bar set-up is ridiculously bad - no one really knew what they 
were doing back then with aero bars.

Would you have any other insight as to the actual frame builder?
