    That is all true from a purely theoretical, material science based perspective on this, so the misconception is understandable. However, please mind that in practice, when it´s about bike components the main criteria is that they have to be lightweight. So when it´s about bike parts we always compare the stiffness of steel parts and aluminium parts of the same weight and as you explained correctly:

    aluminum parts can be stiffer than steel parts at the same weight

    Obviously that results in the aluminium bike parts being generally stiffer than the steel bike parts they are compared to. I apologize for any confusion I caused but I am a bike mechanic and not a metallurgic engineer.

      It’s true that I can get caught up in the nuance sometimes. That said, you and I both understand the details behind what you’re talking about but odds are a number of people lurking in the comments don’t. All I was really trying to do was nudge those people away from “substituting aluminum in place of steel with no other changes will result in a better part”.
