let's assume that I find that it does fit and that I do like how it rides.
Pretty sure you will like the ride quality but knowing for sure takes a couple of months of riding. Do not fool yourself into believing that you know a bike until you have actually spend considerable time fitting the bike to you (assuming it is a potential good fit) nor should you fool yourself into believing that you can evaluate ride quality in a couple of rides.
I always ride a bicycle for the better part of a season before making any upgrade or restoration decisions. Doing this will help control the urge to spend money just for the sake of spending money. Doing this will also help you understand if you really do like the bicycle. And, finally, or not, doing so just might help you want to keep the bicycle just the way it is.
My opinion, only, of course. And it applies to every bicycle that I have owned and retained as a keeper. That said, I am working on one, right now, that will not follow that evaluation process. Of course, the one I am working on right now will never become a bike I ride much. It is just too old and too unsafe to ride in today's traffic. That said...
This old
Legnano Gran Premio is in need of paint and art. Or is it? Been riding it for two years, now, and just can't bring myself to redo the paint and art. The bike has grown on me. You'll see...
