Well, if they are novel methods and not banned, then there is no cheating involved. I don't think they have to reveal their methods or am I wrong? Do they have to reveal all materials for aero stuff as well?
They are certainly not using EPO or some hard-banned chemistry from the list.
Do you want to ban everything? There is a thinking everyone should have the same equipment/training/everything. But then it's not a real competition, is it? I mean, sort of communism, no innovation.
We decided to ban some pharmacy for whatever reasons, but most stuff isn't banned.
And most stuff isn't available to everyone. That's the very essence of competition - to have an edge. To be innovative.
To the first bolded, using a substance before it is banned does not meet the ethical requirements of fairplay, for which the substance eventually gets banned. For example, this was the case with EPO, which wasn't publically discussed until Johannes Draaijer of the Netherlands was presumed to have died from the drug in 1990. Initially, following being made illegal, there was no test to reveal EPO in the blood. So the doctors figured out ways to keep the hematocrit level below the 50% limit for health reasons. In short, EPO flooded the peloton, but so long as you kept your blood values in line "no infringement" of the rules had occured. Of course, the performance advantage gained remained the same.
When EPO remained accessible to only but a few, although not yet banned, it still constituted doping in terms of physical enhancement. When EPO became widespread, although banned, it was undetectable at first and so riders rode doped, even if declaired "clean". Thereafter, with a test to dectect the drug, everthing got more sophisticated and only the best money and therefore best doctors, as well as best responding, could ensure a champion's success. Armstrong personified this. It's no reason he paid Ferrari 1 million to work exclusively with him. This debunks the idea that everybody doping "levels the playing field". And then new drugs, novel treatments combined with best performance science, which only the well funded teams can afford, makes an arms race that renders opaque what real talent can achieve on a truly level playing field.
I'd say the big shift in doping verily skewing the playing field, because it has always existed in the sport, occured in the early 90s. From there onward it's become increasingly difficult to know the true athletic value of each rider on the road. Certainly talent plays a part, but it has become impossible to know how much of a rider's success (like Pogacar's) amounts to mother nature or highly sophisticated artificial enhancements that are either outright doping or contrary to the spirit of ethical sport. Naturally only having access to enormous economic resources, through which corruption may also be permitted, gets this effectively done.
To the second bolded, it's simply the market structure that allows and makes necessary the other battle front of the arms race: tech advancement of equipment. Back in the 80s, for instance, doubtless there were descrepancies in equipment quality, but more or less the peloton rode on the same machines. Its nothing like that today, where, again having huge financial resourses, some get to ride on machines and wear clothing that literally gives a huge advantage over other riders on less well funded teams, who can't afford the most expensive and performance enhancing models/materials. It's good for the the business of the sport, but what does it say about another aspect of cycling at "two-speeds"?
