I go with what I experience. I have to say the snob value roadies attach to in wearing fancy team costumes is darned obvious. I encounter several guys regularly on my commute that wear USPS Lance-lookalike gear. If I'm on a shiny, drop-bar roadbike, I might get a nod. On my touring bike, a faint acknowledgement. On the crappy looking fixie, nothing. The MTB towing a trailer... hah!.
Interesting to see such passionate defence of wearing the billboards. You guys really don't like being called poseurs, do you?
