Why? Because all the evil bike shops have formed a union to stop selling road bikes to mutant aliens. Just like they did to all the other groups mentioned in the "Why no XXXX road bike riders." This time they went too far. The government plans on interjecting on behalf of the mutant aliens with a $700 billion bail out plan to assure there are an adequate number of road bikes for them. However, since aliens take on the shape of humans within 24 hours of landing on earth, you will not be able to tell who in your pace line is an alien unless, of course, you know the secret password.
