I want to write an article for my website, MY "TEN SPEEDS" that helps us all use frame characteristics to help date frame and fork sets. I am particularly interested in developing an understanding of what was popular and when. For example, braze-ons. When did each begin to appear - rear derailleur cable guide on chain stay; transmission guides brazed onto the bottom bracket; under bottom bracket transmission cable guides; shifter braze-ons, front derailleur braze-on; brake cable braze-ons on top, the side and underneath...

If I can assemble a reasonable concensus of information from this forum, I will publish an article on my website. I might add that I am thinking of making MY "TEN SPEEDS" free to all who visit.
