I think they're "road warriors" if they're friendly, but lots of Lycra-clad riders with expensive bikes are more properly termed "snobs." It all depends.
However, I have to put in a good word for Lycra. I vowed I'd never be seen in it--not just because my body is far from shapely, but because of the snob association. But midway through my commuting career I purchased Lycra-Spandex cycling shorts and tights (one pair of the tights has a "wind front" to protect against cold breezes)--and, as they say, I never looked back. So much more comfortable than anything else I'd worn! Never mind if I look laughable. Comfort is important, and it's Lycra for me--for that reason.
