Dr. Maserati said:You need to view what JV said...."Even if all athletes were doping with the exact same products, the best athlete can no longer be defined by competition"....
Equipment is pretty much standard and while different athletes train for different priorities training is fundamentally the same, but there are races from just a few kms (prologues) to almost 300kms (MSR), flat races to races with multiple col's...... and then there are the GT's.
All of these give oppurtunities for athletes of different abilities - but with a natural selection of those considered "best athletes".
Again, JV answered that when he wrote....
"If doping comes into play, it creates a moral dilemma for some and less so for others, driving away some athletes who may be better prepared and more physically talented, but have moral issue with the act of doping."
I was thinking about the development in a historical perspective.
For instance some riders will probably see bigger improvement in performance by using powermeters than others. It doesn't mean that powermeters are bad.
