I think the "classic" formula, like "compact" frames, is just another way of putting the seat, bars, and cranks in space. Where those parts are put is determined by your skeletal dimensions and muscular flexibility. After that, you connect the dots. It doesn't matter if the tubes are straight or curled like spaghetti, if the bike doesn't fit, it doesn't fit.

Where are you? I'm trying (not very hard) to unload a couple bikes that might fit you. Have a look: http://home.comcast.net/~jeff_wills/Gallery/index.html
