I hear people say that they won't wear a modular (flip up) helmet because they could pop open in a crash. I also hear people say that they refuse to run a sport-touring type tire because they might not offer enough grip for their type of riding. But..... Has anyone ever actually had these issues? Have you had a modular helmet fail? Have your sport touring tires actually caused you to crash? There are probably many other examples of this kind of thing out there. I'd love to hear more of them. So here goes! Bust the myths, or prove them right!!! Thanks.
