FWIW, I no longer understand what the heck anyone means by hybrid. Or, for that matter, by road bike. Sure, they're terms that have some broadly applicable trends of characteristics that make some sense and allow them to be used as stereotypes, but there are so many exceptions and permutations in the details that matter significantly to the intended use and issues at hand that I find them no longer useful. Somewhat like those other terms Democrat and Republican these days.
