Testing a cyclist to fine the optimum aero bike fit.
Adjustments = aero bars length & angle, stem length & height, saddle height & fore/aft, top tube, clothing, aero helmet, pedal Q factor, etc. Plus the cyclist’s wattage & heart rate are measured. Body type & size play a major part (the shape of your shoulders & back will determine which aero helmet yields the best results) Wind tunnels have specialized testing protocols for cyclists
Using a cyclist brings too many variables: body size, type, sex & ability to be consistent. What size cyclist do you use? The largest factor is for a cyclist to be consistent! Testing takes ~ 2 hrs: set-up, repeat 3x for accuracy, change yaw angle, test again. The cyclist MUST have head & body in exact same position (even fingers & toes need to be pointed the same). Reality is it can’t be done. If required, then manikins are used & this drastically increases the cost.
There are 2 types of wind tunnel testing (part 1)

Why did you test it without a rider?
