After some recent position changes (see video below for new position) I wanted to do some aero testing.
I got in touch with a guy in UK who is a bit of an expert in aero testing using the Chung Method and aerolab on Golden Cheetah.
Basically ride several times around a loop without changing position or touching brakes, ideally with V low wind and no cars.
I did this tonight, analysed the data (99% sure accurately) and got a CdA of around 0.31…which doesn’t sound right for a TT position so anyone have any ideas?
I’ve checked bike and no issues with brakes rubbing etc.
All I can think of is my power meter is over reading- it’s a 4iiii single sided, so maybe I don’t pedal evenly or inconsistently…or I’m as aero as a brick wall!
Any ideas appreciated!
