The Wedgie is an integrated water bottle and tool kit holder for triathlon and road bicycles. This video showcases the results of Aerodynamic testing at the A2 Wind Tunnel. The tests prove that there are significant power saving (due to improved aerodynamics) for the Ironman, triathlete and cyclist.

Why did you test it without a rider?

There are 2 types of wind tunnel testing (part 1)
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

Part 2 - Test Products
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.
