This was a topic at a relatively recent meeting of our club. Fortunately, there were six different makes of Boron/steel tubed bikes (Dedaccia OEM 16) available, all around the same size. There were also two Bianchis available, both in size 60cm, one EV2, one Boron steel. The boron bikes all had different handling characteristics, but the same steel "feel" The aluminum and steel Bianghis, though of identical geometry, were, as expected, very different in road feel and pedal/bar feedback.
There were enough other frame available of different steels, that I felt a true test was in order. Taking a hint from wine taster's "blindfold" tests, I came up with a totally empiracle solution. I blindfolded ten riders, on ten different bikes, and sent them off on a 20 mile ride. After 300 yards, all riders were no longer physically able to continue, and all bikes were rendered unrideable.
I think this pretty much settles any discussion on this, as I feel my point has been proven to an unassailable level.
