Man, that word "Spandex" is freaking powerful. It seems like the minute it's injected into any one of these threads, fists immediately start flying.
I think many (too many) writers use "Spandex" as a metaphor for all things people perceive as "silly" about bicycling. I would never wear any of the flamboyant cycling clothes at the LBS, but I'd imagine there's a reason so many cyclists do. Good for them. I'm glad their asses are on bicycles. Full stop.
