I continue to believe that with the aero bike he performs worst on climbs, it's not only a matter of estimates of power output being lower, even than dauphine, but of how he looks on the bike. If you look at his performances with the v series he always arrives to the last kms in total control, he never looks like he's over his limit, he has his mouth closed, he looks comfortable on the bike. In this tour both in the tt and hautacam I did not have the same impression at all, plus his pedalling looks less smooth, especially as soon as the gradients go above 7.5-8%
