There are some people that believes that you can be as low as your back can support without pain and eventually will generate the same power as in a less aggressive position.
I used to believe the same, but I’m sustain power in aero position anymore… So this month I’m gonna ride 2cm higher to see what 's gonna happen.
How do you guy find the optimum power x aero position ? ( Just testing in the field ?? ) I don’t believe that a fit session will address this issue since you don’t test your endurance in a such position fitted .
