There is an incredible amount of bullshit put forth about steel, and subjective discussions of stiffness absent any kind of objective testing are often at the heart of it.//
//a 3kg mild steel frame will be stiffer than a 1.5kg 953 frame.
you are normally better informed. are you not well? lacking some sleep?
2 identically dimensioned frames in tube O/D and wall thickness but one made from cheap cro-mo, the other a high end steel will have the same stiffness because the dimensions are exactly the same* one will be stronger than the other due to it's better materialproperties.
it's these properties of high end steel that enable thinner walls for the same strength and that results in a lighter frame. as long as you don't go silly so that the tubing beercans at the slightest provacation
*yes there will be differences but very very small so of no consequence.
