I would like to encourage you to contribute measurements of your classic frames to the Bicycle Geometry Project of Dave Mann. He has compiled data on over 200 frames so far. His site proposes categories based on clusters of similar specifications and has illuminating discussions of what it all means.

My original intent when I opened this subject was to discuss which geometries of various classic and modern steel frames were appropriate to various uses and classify frames into mutually agreed upon categories.
I now realize that this is a doomed activity for several reasons:
1. While not completely off-topic it is not central to the interests of the Classic Rendevous list.
2. Mutual agreement on frame geometry and terminology is highly unlikely, the British have their terminology, the French, the Italians, and the Japanese have theirs, and cyclists are so independent...
3. Dave Mann is well down the right road already!
I still feel that there is value in the inquiry into fine tuning frame geometry to intended purpose. I have purchased many bicycles only to discover that they were not what I expected or hoped for. I continue to search for excellent classic examples in different categories of use: IE: An almost racing bike with more comfort for riding centuries. A very comfortable but still fast and light bike with rear rack and fenders for everyday use. You get the idea.
