I totally agree with Toadmeister that the strongest steel alloy has a higher tensile strength than the strongest titanium alloy, and that titanium has a better strength ratio, although I admit that I have no idea of the relationship of tensile strength and suitability for bike construction, As someone who rode a Schwinn Paramount made of Reynolds 531 and a Samson titanium interchangeably for years, I will say unequivocally that titanium's vibration and shock adsorption ability make the titanium bike more comfortable. It is these two qualities that make a titanium bike more crash resistant than one made of steel.
