I'll be interested to see what the more experienced velomasters have to say, but my impression is that the geometry of even the race bikes of 30 years ago is considered to be more sport touring than the bikes now. Head and seat tube angles of 72 to 73 degrees used to be considered steep, but nowdays I think the racing bikes are steeper. I will wait to hear from those who know more though. I don't remember seeing any specs on the early seventies Gitanes, but as Dirtdrop pointed out earlier in this thread, at least some of the Peugeot PX10's had steeper angles than the Td'F. I've never seen a Super Corsa in real life, so can't speak for them.
