Echoes said:On the Tour of Flanders, he attacked on the Molenberg and not the Koppenberg, along with Boonen. But it's only on the Kapelmuur that you could say he was weird, attacking seating on the saddle, casually. Then of course, his bike changes around Mater, just shortly before the Molenberg was feeding conspiracy theories but what does it lead to? We have no evidence anyway.
My non-expert opinion is that Cancellara had taken a look at Boonen on the climb and realised he was cooked, possibly even cramping. Cancellara looked comfortable on the gear he was using and simply turned the screws slightly. Boonen was in and out of the saddle and clearly in trouble. The `attack' was a relatively small acceleration by Cancellara, but a big collapse by Boonen. I don't find it odd at all that big guys should want to attack from in the saddle. This I think is Boonen's account of what happened as well. So me it's a no to motorised doping, chemical doping well that's a different matter.
