I read several of your recent posts and what transpires is a disturbing anti-French sentiment, much deeper than just looking at individuals and questioning their performance. I feel sorry for you. As far as I'm concerned, I will wait to see data, watts, comparisons, to forge an opinion. You are reactiong with your guts and spitting venom because your dear Piti got his tail kicked. i feel sorry for you...not for Piti. What a pity
Considering how many riders were close to each other until the end, that many teams were competitive including having a highly placed GC rider, there seem to have been some sort of an even playing field. Whether all were clean or all doped we may not know for another 10 years.
Exception is Nibali, but again, it was pretty much accepted before the start that after the two favorites CF and AC he was the strongest rider, with all other 'contenders' one notch below.
