I disagree on this one. Basso always targeted the Giro and would and still will ride the Tour in support of Kreuziger and Nibali. That's what he is stating is nearly every interview he gives.
And that's a good choice for him. The Giro is winnable for him, while at the Tour even the podium seems out of the picture.
Every interview I read of his, again from cyclingnews, who don't know between right and wrong state that he is going for the Tour.
Plus I was speaking to one of the Liquigas boys in January and they say Basso is all for the Tour.
Edit: Then I read an article on velonation from a while ago saying Basso is for the Giro.
Cyclingnews sucks with the information they give.
