Thing is if Wiggo was doping you'd see more than just the dogged riding style he currently has. If he was on EPO he would have actually attacked Evans on Stage 8. Rather than vice versa. That's what Dopador would have done and did do. Same with Pharmstrong. Wiggins has never really let rip with that sort of droid fueled blitzkrieg the top dopers can pull out when needed. He's just in really really good form in a year in which no one else is, and in which it seems dopers are in a small minority. His TT performances are simply the performances of a man in peak form riding his preferred discipline with the holy grail of cycling to aim for.
