The top tube is 21.25, 53.9 cm. I believe this is the A-Frame model and was made in the mid 1970's.This is the best guess I can make from my research online but I don't know the exact date or model, so please see pictures for details. These are beautiful custom made bikes from the eisentraut shop in Oakland, CA. This bike is a 9 speed Campangolo Veloce components. The frame and components are all in great condition with no rusting.
The only problem at all is that there's a leak in the right tire. Please look at the pictures for details of all of the components and text me with any questions.
