I totally agree with everything you are saying. But you have to consider the application of said material. A bike frame that bends is a failed part and it does not matter how much more force it can resist, it is now useless. I also am speaking of catastrophic failure by the way, as in there is no bike anymore after this crash type of incident. In these cases, I believe the carbon bike will endure a greater amount of force than a steel bike. And that’s also while being far lighter because at equal weight there is really no contest.
