There was another thread about the staggering lack of form of Ivan Basso, though it isn't up now.
At any rate, it's shocking that a former Tour contender and a twice Giro winner lost over 6 mins. to Martin in yesterday's time trial. Even considering that he does not excel in the discipline and perhaps he's riding cleanish now.
Could it possibly be, however, that since not near top shape now, also because of his recent crash on Etna, means he will also ride the Tour de Swiss as final preparation for the Tour? If this is the case then he could be just cruising through the Dauphine to save energy for the Swiss event, otherwise if he pushes himself too hard now, and then goes to Switzerland, he won't have anything left for July. Whereas by not trying now, and merely riding at base levels, will mean he can reasonably feel that the Tour de Swiss should bring his fitness just to the right fevered pitch for the Tour.
I'm just speculating, because if he does not have this scenario in his program and isn't riding just to keep the engine warm now, then he's in deep do-do for July. Though I can't see him not having some strategy, or that he really is this bad because just that slow.
In any case, his performance was rather dismal.
