Lycra, helmets, clipless, blinking lights, cyclometers, gps, cell phones, "I almost got run over!", "I got hit", "Another biker killed", followed by..."how do I carry my gun?", N+1, pie, beer, carbon, and most recently.......mountain bike invasion .
RAGBRAI, century, metric century, metric system, "Is a fitting really necessary", "what size bike do I need", "how do you clean your chain", saddles...followed closely by another Brooks saddle thread....

REPEAT.
