Gazzer, that bike is stunning. I love the look of the period-correct Campy stuff on it. Mine is ( and will stay) modern 10-speed Campy w/triple because there is no way I can ride in my neck of the woods wihtout it. A 42X28 is not going ot get it done for this Clyde.

Yours looks to be close to mine is size. The rear triangle geometry looks very similar, but the head angle on yours looks to be little bit more slack. I'm guessing you can ride that puppy all day long.
