It's taken me a while to get up to speed on this thread, which is pretty long and pretty repetitive, and the prototype cannondale thread, but it's very interesting.

Bob, have you noticed this quote:

When she was a math professor at Northeastern University in the early '70s, she built this aluminum frame in an M.I.T. I.A.P. project, but never finished building it up. This is one of the first fat-tube aluminum bikes, and, in fact the frame was an important exhibit in the legal proceedings between Cannondale and her classmate Gary Klein.
I assembled it for her in the winter of 2005.
