airstream said:No one knows for sure. I just try to reason in general. Tyler said EPO gives about 15% endurance extra. Doping that was used before EPO was not so effective but I doubt it gave much less. 15% in a sport where sometimes seconds decide a winner is cosmos, an irreal edge which one will never be able to close with pure talent.
IMO the thing is oldies do consider themselves clean because they had no possibility to ride on hard peds like epo and transfusions
You're right on here. leMond has said numerous times, those types of drugs weren't easily available, or used during his era. I'm sure there were exceptions to the rule, but mostly just introductory usage.
