I am working on this as a "Homework Bike" for the Silicon Valley Bike Exchange. I am curious as to how old it might be......




It has crimped seat stays but they are nicely pinstriped



Elegant pinstriping on the top tube as well




Derailleurs are Campagnolo, rear is a Gran Sport



Brakes may help date the bike - they are Weinmann but not a pattern I have seen before.



Crankset is close ratio - nice paint fill in the relief.



The rear wheel is a replacement with an Asian hub and steel rim but I suspect the front to be original. Weinmann alloy rim with a Normandy hub that has round holes, another thing I've never seen before.




Your thoughts and observations on this bike are most welcome!
