I saw a pic from the TdF where Lance is in front, one leg cocked way out to the side, hand in the crotch, one hand on the bars, just wizzing away, while three of his teammates are in a line behind him, each pedaling with one hand on the back of the guy in front of him, pushing the guy in from of him... it was 3 guys in a chain, all connected, and all pushing Lance. At first I just thought they were in a pace line, but then I noticed Lance wasn't pedaling. LOL.
