Nobody has ever shown that Cancellara was cheating there. Maybe he's just a monster. When Joop Zoetemelk casually disappeared from the front of the pack in the 1985 World Cycling Championship nobody could believe it because Joop was 40 years old. Nevertheless, he did it, and there was no stealth motor technology at the time.

So far, with cycling, P(discovered cheating later | outrageous) ~ 1. Some people will believe that when they go indoors the sun stops shining because there is no longer any proof. It's certainly a strict way to seek one's knowledge. Others have a different view.
