Afrank said:Agree with this, Been watching Quintana for a while now. And while Froome with practically every attack and every win screams PED's, Quintana seems much more natural in his performances. His progression has been very normal and his performances all have been well within the bounds of what he should be capable of.
Yes, improving fitness during a grand tour and holding it without getting shelled early in the tour is almost impossible without artificial enhancements.
