I heard Steve say that aluminum is stiffer than steel. No, it isn’t. Aluminum Young’s Modulus is 10 million psi, whereas steel’s is 29 million psi. Steel is three times as stiff than if the same geometry were made in aluminum.
What makes aluminum frames stiffer is that the lighter weight of aluminum allows for bigger cross section frame tubes. It’s that geometry that makes those aluminum frames stiffer. If you created an aluminum frame with the exact geometry and wall thickness of a steel tube one, the aluminum frame would feel like rubber on the track.
