That makes sense. I'd still like to know about the tubing gauge tho... I' m positive that at least on my bike they were using something thinner. I wa s a 130 lb lightweight, strong perhaps but not heavy, and I could rub the chain at will. For years I heard people complain that Peugeots were "flexy" and th en just last month I read an article (in Vintage Bike Quarterly I think) saying
that flex is not necessarilly a bad thing... energy lost to flex in a steel frame is not dissipated (as heat for example), but returned at a later part of the pedal stroke and therefore is not really lost. The effect can actually be
beneficial, as in the sprung floors that gymnasts use for floor excercise
routines.
