I'm still wondering why the rim makers are using the same design originated in road racing, where the tire profile usually follows up the rim sides. Those things are designed to bring vertical support for a heavily inflated tire, while we on MTB use tires which balloon away from the rim. The proclaimed merit of the hookless sidewalls is another thing leaving me speechless. Why can't we think of a rim profile/bead hook combo that drives the impact forces laterally rather than vertically? Something resembling more of a "D" shape, rather than a "A" one. And make the sidewall end in a rounder shape, just like the dirt/MX bike rims do.
