The Velominati have compiled in one handy and humorous volume the entire anthropology of the dedicated club rider.
When today's club ride started our group was joined by a youngish woman I had not met before. I could see that she was properly kitted out in black bibs and a leZyne pump peeking out of her jersey pocket. No European posterior man satchel was to be found on her clean and silent steed. Her tires were properly aligned over the wheels. Her barely padded saddle was slammed back, level, and 8 cm above her bar tops. The appointed hour of departure arrived and she, sitting casually deliberate on her top tube, suggested we delay not even a second. No sooner had we rolled out than my worst fears were realized. Despite her modesty ("Oh, I only ride once a week and I'm not comfortable in groups"), she quickly served large helpings of the V; Dropping us like bad habits on the first inclines, swooping down off camber switchbacks and taking her turns in the wind with nary a thought.
Having just read "The Rules" I recognized her for what she was, The Woman with the Hammer and a true Velominata Rule Fundamentalist.
THIS is anthropology. Leave the kinship rituals of long forgotten aboriginals to others and take a couple of hours to learn about your neighbors. Highly recommended.
