Okay, I didn't go through EVERY page on the "Commuter Bicycle Pics" thread...but, on a cursory glance, I didn't see many pictures of road bikes.
I've been to the Road Cycling sub-forum and have seen some absolutely gorgeous road bikes and say to myself, "Self, these are rolling works-of-art and have the latest/greatest components, etc...and since these are magnificent machines and are meant to be ridden long distances, built like tanks but weigh next to nothing, are effecient, and are the epitome of cutting-edge design...wouldn't they make great commuting machines, too?"
I've seen some spectacular bikes in this Commuting sub-forum (as well as the other sub-forums, for that matter) that are obviously comfortable, light, simple, utilitarian, etc. Commuting bikes seem to be designed by manufacturers and built-up by their owners to be more simple and more comfortable, but I would think that some people would opt for the best of both worlds.
What happens when the two worlds collide? What happens when you take a road bike and make it your daily commuter? Don't folks do this very thing sans the "yellow jersey" or the lycra/spandex shorts and special shoes?
This thread is a bit tongue-in-cheek and not meant to be judgemental in ANY way, but I am curious as to why more folks don't use road bikes as their daily commuter.
