Sooo we can safely say Jan Ullrich (a TDF winner) with his 70-80 rpm cadence is safely in the non-aerobic range? Or maybe even Santiago Botero (2002 World TT champion) and his 50-60 rpm cadence... Both these guys accomplished what they did anaerobically by what you're saying correct?
I'm not sure how you got it in your head the aerobic threshold is somewhere ~90 rpm range; it's not. If you need a defined number the crossover point is probably closer to the 45-50rpm range. Which is why many people say for a climbing cadence just keep it above 55-60rpm and you're good. The ~90rpm number is just what a 'typical' person will experience the most efficient tradeoff in regards to muscle strength and endurance vs cardiac endurance. There's people who fall in anywhere from 50rpm - 130rpm as the best cadence for them, all the while still being primarily aerobic.
