If you are a true cyclist, all your wishes came true.

If you never heard of the Velominati, but ride a road bike? Get yourself together:

We are the Keepers of the Cog. In so being, we also maintain the sacred text wherein lie the simple truths of cycling etiquette known as The Rules. It is in our trust to maintain and endorse this list.
The Rules lie at the beginning of The Path to La Vie Velominatus, not at the end; learning to balance them against one another and to welcome them all into your life as a Velominatus is a never-ending struggle waged between form and function as we continue along The Path towards transcension.
