Message	entertaining an aluminum, titanium, or C/C roll bar, the weights savings are negligible versus other steels. It is 2x that of titanium, and 3x that of aluminum. Stiffness to weight ratios of chrome-moly to aluminum and titanium are consistent with the increase in weight, i.e. the stiffness (Young's Modulus) of chrome-moly is 2x that of titanium, and 3x that of Al.
