Doping is nothing new?

Seems as though an old bicycle was dug up recently on the Paris-Roubaix course. According to bikeradar.com the bicycle appears to be from the 20's or 30's. Although there was no race number attached or any way of identifying the bike, there was still a water bottle attached, with traces of cognac and pastis!! Seems as though some individuals have been cheating the system for a long time.
