There seem to be a theme, since Bjarne Riis, did it, Indurain did it, so I guess if you win the tour, you have to throw the bike. Seriously, I heard the Mechs. only just finished assembling the bike on Friday, so not much time to get used to the bike, and not enough time IMO to adjust and let the bike settle in, which means you don´t trust the bike as a rider.
