Is there a curse? Naah, I don't think so. Let me make a run-through of the latest World Champs (skipping Costa as it's too early to tell):
Gilbert: Did have a rather medicore 2013 season, but he also had a rather medicore 2012 season. Of course everything is medicore compared to his 2011 season.
Cavendish: Only one three stages in the Tour, instead of his usual five (still better than the two he got last year, though). However, this was probably more due to the fact that he wasn't the protected rider on his team.
Hushovd: HAHAHAHAHAHA! I think we can all agree that he wasn't cursed.
Evans: Won Fleche Wallone.
Won "The mud stage", held the pink jersey for a day and won the red jersey in the Giro.
Okay, he couldn't manage more than 26th in the Tour, but he wore the yellow jersey for a day, and the day before getting the jersey he got a fracture in his elbow.
Ballan: I don't remember much here...
