They call them "racer weenies" or "weight weenies". And for those who care more about how they look than how much they actually ride, bikeforums has a special name: OCPs (Obsessive-Compulsive Poseurs). Some of the OCPs actually do a nice job of making fun of themselves about it, even while they continue to obsess about getting the handlebar tape to match the kit, and the booties, and the helmet and the tires...who says girls are the ones who get wound up over accessories??
