You guys are forgetting to mention the important subspecies of the road bike coffee shop poser.
I'm sure you have them in Seattle, I've seen them in every single town I've lived in.
You know, the folks who get decked in all their riding clothes, put on their road shoes and get on their perpetually clean shiny bikes, and ride 4 blocks from their house to hang out and drink coffee in public.
Their clothes are never dirty, their bikes are always shiny, and their shoes always look nonscuffed.
Don't forget them. I think they're the ones that reproduce.
