What is with that

So am I reading the BMXer mag that comes with the ABA membership. I am going through the rules and come across the "drugs" section. For 2007 the rules on stimulants will follow UCI rulings. So I go to the UCI page a find Caffeine. " The amount of caffeine allowed per rider may not be greated than 12 part per post event testing, this amount is comparable to a 12 once caffeinated beverage" Now the question is should the barn stop selling Red Bull to all the riders. Makes it pretty tough for a pro rider to protest a rider when the event is selling the stimulant in question. I am sure after 1600 feet of racing bmx not much has burned off.
