Aerodynamic testing of different high-performance helmets

An evaluation of the different helmet aerodynamic efficiency was performed on the 16th of June 2022, in Bilzen, Belgium with a temperature of 25.3 ºC, a humidity of 50 %, air density of 1.189 kg/m3. Two UCI Continental cyclists from X-Speed United performed 3.5 km tests with different helmets. One was using a Scott TT bike, and the other was riding a Giant TCR road bike (riding on the hoods). Each helmet did at least two runs with helmets 1 3, and one of the athletes did four tests with helmet 4.
