This unique
air hardening property of Reynolds 853 provides additional stiffness
through reduced micro yielding at the joints, allowing stiffer frames
with excellent fatigue strength (when compared to standard chrome
molybdenum) and excellent ride quality."

Well that settles it then. Alloying and heat treatment CAN alter the
modulous of elasticity of steel. This sentence, written by some
advertizing flack, ovbiously disproves the results of more than 200
years of metallurgical science and many, many thousands of tests. Just
think of all the textbooks that will have to be re-written. The
implications for spring design alone are enormous.
