Highly funny thread.
Spanish doped, Talansky clean, Froome probably, okaaay.
The correct answer though is:
1-10, all clean. No positive so far, so they have to be regarded as clean.
Are they really clean or just doped so well that it can't be detected? In the end who cares. Ah yes, some moralists who demand that cyclists are perfect humans. Health concerns? Good doping is very likely much healthier than riding completely clean, but the whole doping-mania, cheater here, cheater there, in the end is not about health and not about fairness, it's about moralizing, dissing riders you don't like etc.
10 years ago not clean, now maybe yes? Doping is not Doping, EPO, CERA in huge quantities are out, microdosing maybe, maybe less effect, or more traditional methods, the next wonderdrug not there yet. So yes, it's not as fast as in the EPO high era anymore. Doesn't mean there is no doping anymore. Look at athletics, women in the 80es, Koch etc, all the records still there. Is athletics now clean, and has been since the early 90es? (Exception the turtle-blood army). Or have controls just improved, so that the most effective products, male hormons, are detecatable, so aren't in use anymore? I'd say the second. Same for cycling. The drugs that REALLY made a difference (but where never a substitute for training, on the contrary) are very likely mostly gone, the other ones not.
Very likely all top athletes are usually at a similar level when it comes to sports medicine. Which is what doping is. If then it's on the legal side or not doesn't matter unless somebody is caught. The line between legal and illegal sports medicine is pretty random anyway, performance enhancing, unhealthy. Isn't sugar perfomance enhancing? Is EPO unhealthy?
But ok, now I know that Talansky is clean, Froome probably, the rest very likely not. Thanks.
