There is an interesting Legnano on the bay right now.
Since it is '58, there are no braze-on cable stops, etc., they only used clamp-on guides, etc. What would be the differences between a road bike and a track bike? I can think of the following:
Rear drop outs
Rear spacing (maybe?)
Drilled fork for brake (although I have seen Legnano track bikes with a factory drilled fork)
Anything else? Also, I have been looking for a track bike from the fifties and was thinking I could convert this one. Good or bad idea?
