Some of my favourites, respectfully swiped from the Velominati.
The minimum number of bikes one should own is three. The correct number is n+1, where n is the number of bikes currently owned. This equation may also be re-written as s-1, where s is the number of bikes owned that would result in separation from your partner.
Harden the fuck up.
Tan lines should be cultivated and kept razor sharp. Under no circumstances should one be rolling up their sleeves or shorts in an effort to somehow diminish one’s tan lines. Sleeveless jerseys are under no circumstances to be employed.
When wearing a cycling kit and enjoying a pre or post ride coffee, it is only appropriate to drink espresso or macchiato. If the word soy/skim latte is heard to be used by a member wearing cycling apparel, then that person must be ceremonially beaten with Co2 canisters or mini pumps by others within the community.
Legs are to be carefully shaved at all times. If, for some reason, your legs are to be left hairy, make sure you can dish out plenty of hurt to shaved riders, or be considered a hippie douche on their way to a Critical Mass.
Team-issue shorts should be black, with the possible exception of side-panels,
which may match the rest of the team kit.
Facial hair is to be carefully regulated. No full beards, no moustaches. Goatees are permitted only if your name starts with “Marco” and ends with “Pantani”, or if your head is intentionally or unintentionally bald. One may never shave on the morning of an important race, as it saps your virility, and you need that to kick ass.
If you are out riding in bad weather, it means you are a badass. Period.
