'I am not saying that the TdF is clean, I'm not certain Sky are clean. But I am certain that the Tour is much much cleaner than it has ever been, and that the whole Sky set-up from top to bottom, origins to today, make it more likely Sky are clean than most other teams.'

Pointless comment, you cannot be certain of anything. The advances in doping that you are not now or ever going to be privvy to mean you know fuck all. None of us on here do. If Sky have all this money it is totaly naive to think they haven't got the very latest access to 'dope'. For all we know Wiggins could have undergone gene replacement therapy.

Its not impossible, he has just completed a superhuman feat by winning all those tournaments. Its never been achieved before ever. Your telling me thats due to tighter lyrca shorts. He could well be a freak of nature but you cannot say 'for certain the tour is cleaner', more likely its cleverer.
