Cycling Rivalry - Contador vs. Schleck

For several years it was Alberto Contador vs. Andy Schleck. And who doesn't remember the infamous "chain gate" of 2010 TDF when Contador attacked after Schleck dropped his chain, and Contador took the lead. It produced some great quotes:

"If you draw your sword and you drop it, you die." - Ryder Hesjedal

"My stomach is full of anger, and I want to take my revenge." - Schleck
