In the world of cycling, Eddy Merckx is a legend. He is the best cyclist ever; having won 5 Tours de France, 5 Giro d'Italias, 3 World Championships, 7 Milan-San Remos, and having beaten the World Hour Record, to name a few of his victories. In all, he won 525 races, an all time record. And that is why they called him The Cannibal.
Eddy Merckx was and still is a maniac of maintaining his bikes. He would often stop in the middle of a race, just to adjust his seatpost by a fraction of an inch (and he would still win the race).
