You're correct in that there is a genetic ceiling on VO2 max, but people are generally arent anywhere close to it if they are not athletes, therefore it is possible to raise the VO2 max a fair amount by training. for example, lance's VO2 was in the low 60s after cancer, and a peroid of chillin, drinkin beer, and playing golf. he trained a lot, and his VO2 max was in the low 80s.
also VO2 max is measured in ml/kg
/min. that kg is the kg of body weight you have, meaning that losing weight can increase your VO2 max.
lastly, VO2 max is simply a measure of how much oxygen you can take in in a given amount of time per kg of body weight. this doesnt automatically mean that you'd be a good cyclist, since you might not put out much power at your VO2 max. power is what makes you a good cyclist, not VO2, not even LT. If your LT HR is 99 percent of your max, but you only put our 100 watts, then you're gonna get dropped. conversely, you could have a LT thats only 40 percent of max HR, but if your putting out 1000 watts, you're gonna dominate.
nonetheless, it is clear that this particular skiier is exceptionally gifted genetically, and he would probably be a better cyclist than me if he decided to start riding. however, the point of my post was that VO2 max is just a small part of the equation that makes a good cyclist/athlete.
