So how did Gianetti know he was a super responder back then? Luck? Even so this takes more than super responding.
There must be an Armstrong factor (look the other way), else, I fear motors. He looks so fresh. Even if motors there must be some kind of corruption involved as I assume his bike would need to be checked. I refuse to believe you can hide a motor from a trained mechanic who knows what to look for - even magnetic assistance. And the relaxed confidence from Pog suggests he isn't worried about being caught.
Motors is really something that would make me stop watching the sport. This is not even cycling anymore, the idea of moving using the power of your own engine... As for UAE, they surely made a series of tests on Teddy before he joined. They measured his current VO2max, anaerobic threshold, assessed how much weight he can lose with a better training and what are his blood values etc.
