Last Sunday, a special kind of auction took place in New York. Under the title "It's about the Bike", seven of Lance Armstrong's racing bikes were auctioned off for the benefit of his cancer foundation. The seven bikes - all from this year's racing season - were designed exclusively for Lance by world-famous artists and brought in total proceeds of an incredible 1.25 million dollars. The "Trek Madone Butterfly" by artist Damian Hirst was the most expensive and went under the auction hammer for a whopping 500'000 dollars. Lance rode it in the final stage of this year's Tour de France.
