Wiggins is talking a good race this year; the competition among the 'defiinitely not doping' riders could be close. If the drugs testers have got something up their sleeve there might even be a surprise winner.
The above quote is taken from the Schleck vs Contador thread but it prompted me to wonder (and I didn't want to go off topic there) - who are the "definitely not doping" riders? I've always wondered if any of the current crop of British riders are not clean. It would surprise and disappoint me if one or more turned out to be, but having followed cycling for a few years now, I've learned not to expect anything! Views seem to be that Wiggo is clean but who else? And why do we think Wiggo is clean compared to the others?
