no one can hold his wheel. Here's the attack on video from yesterday's E3 Prijs Vlaanderen. What the video does not show is that the other riders did not see Cancellara again until the podium. It's also worth noting that before Cancellara buried the peloton, he suffered two punctured tires and another mechanical that forced a bike change. Each time, he had to expend energy to chase back up to the group.
In the wake of Cancellara's dominating victory, Team Garmin-Cervelo manager Jonathan Vaughters explains (here) the need for his team, which is built for the Spring classics, to change tactics for next week's Tour of Flanders: they will have to focus their entire race on marking a single rider, which is perhaps the ultimate compliment to Cancellara.
