well, as far as TdF and sagan is concerned, he might even wear the yellow in the begining, first stage is short very technical ITT in which he is great, then there is short but steep uphill finish in the second stage. He could easily win this one and there there one or two more short uphill finishes in the early stages. In my opinion, this year's TdF is well suited for Sagan. However, we'll see.
