There is cheating in every level of cycling. We have people get busted on state level (even as low as C-grade... though you gotta wonder whether it is worth the money of testing). We have people get done at national level, and pros get done. I'm not naiive, but i think the claims that people competing in the aus NRS are jacked up and this is what enabled them to jump to pro-conti and pro teams is a little unfair and unfounded.
Now alot of you are probably going to disagree with me, and thats ok. However i've raced a few rounds of the NRS, and will do more and i can tell you that what these boys acheive is easily possible clean, cos i ride and race clean. I know i don't win on a national level yet, but i don't feel that i'm out of my depth. If i had the opportunities as the others do (training pretty much full time, heading to europe for 3 months a year + a little more experience) i don't think i would have any trouble taking the next step. People need to quit with the whole "he races his bike pretty well, he must be junked up". this is what is truly naiive.
