To be honest I doubt anyone in the PT ranks has a VO2max under 70, and 80 would almost be the entry point, I would have thought.
LeMond's was 90 something, and Froome is kicking LeMond performances, right? [ETA: and as previously mentioned, O'Grady, Aitken, McGee all tested damn high, as did Will Walker].
The best score from Norwegian professional road bicycle racer Thor Hushovd was 86 ml/kg/min (as listed in an article on

So big fvcking deal, rght?
I think chasing VO2max is a furphy, as it's impacted by doping, and provides an indication of your level potential (perhaps) (pro, pro conti, conti) but is nowhere near as useful as say FTP, for example, for predicting performance. But FTP is also impacted by doping.
Keep in mind - Froome was at WCC as an African, not a Brit. So he had the best VO2max from Africa, with its vast and rich heritage of cycling history and palmares. Or something. (sarcasm right there for the folks at home).
If it was 80, and he was 71kg (5 kg heavier than his racing 66kg), his VO2max appears to jump to 86. But that value is ml/kg/min, and is what is known as "relative VO2max" - ie relative to your weight.
So it's good for rider comparisons, but just coz you lost weight does not mean you can actually consume more oxygen per minute. Your absolute VO2max is ml/min, and would be unchanged.
