slcbiker said:EPO and cortisone are not equal. Indeed, EPO is probably a bigger jump than all previous drugs.
But blood transfusion were going on in the 80s. And amphetamines for much of the century. And those two things can definitely have significant impacts.
There's definitely no good evidence against Lemond.
But there's plenty of posts these days that say everyone in the top 20 (ie. Evans and Sastre included) must be doping, simply because everyone else is doing it. I'm not so sure that if you're going to use that logic today, you shouldn't also have used it 25 years ago. Or 35 or 45.
To clarify, there is no evidence of Grand Tour riders using blood doping in the 80's. Amphetamines were easily tested for and mostly used for the post Tour crits.
