There are "The Rules" when it comes to riding. Many have been hitherto unspoken. Many are common sense, but most are not. Velominati is the official keeper of The Rules. In their own words: "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."
