I may be missing some subjective experience but surely the centrifugal force of a turning wheel is way stronger than gravity that would cause it to slide off. I mean - if it wasn’t than we wouldn’t need mudguards much. May it just be that deep section rims happen to have no flat spoke bed which causes the mud to slide off one side or another? But then any rim with any depth with such cross section should be just fine.

This was the reason why I posted the question. If it turns out the aerodynamics effects are negligible and I were to focus on weight savings, what would be the best example of
low profile carbon rim and how much lighter would it be than comparable alloy one?

So they are easier to build for the people selling them to me at potentially higher margin?
