I'm a bit slow on understanding the markings on Cinelli bars. I know the second number indicates the width, and that the first number suggests the style. What I don't know are how many styles there are, and how close they are to one another.
I have a pair of 64-40 non-grooved which I like and a 66-4X grooved which I don't like so much. So there are two styles. If I liked a 64, would I like a 63? What are the 'descriptions' of these, including the ones I know?
The other markings have to do with the logo. What is the difference between the old and new logos?
Thanks to any and all that can bring me up to date.
