Wind Tunnel Testing

Test Methodology:

All clothing ranges were tested using jerseys and bib shorts from their relevant collection, i.e. Aero 94 jersey with Aero 94 bib shorts. The rider’s hands positioned either on the drops or hoods of the handlebars at wind speeds of 30kph and 40kph, across yaw angles of 0, -5 and -10 degrees (anti-clockwise rotation of the bike, air flow on the drive side). 30 second samples were taken at each condition from which an average CdA (coefficient of aerodynamic drag) was determined.

Data:

The graphs below show comparison of CdA for each clothing range tested at the four test conditions defined in the test methodology: 30kph with hands on drops, 40kph with hands on drops, 30kph with hands on the hoods and 40kph with hands on the hoods.

Results:

The results show that the Aero Recycled range performed the best across both reference speeds and in both the drops and hoods positions, although very similar results were also obtained for the Aero 94 2 and Aero 94 kits. When comparing to the baseline range over a 3hr club ride, the drag reductions equate to:

★ 9.3W saving at 30kph on the drops, or a 250 second saving (+0.64kph) at the same power
★  31.7W saving at 40kph on the drops, or a 278 second saving (+1.27kph) at the same power
★  15.4W saving at 30kph on the hoods, or a 366 second saving (+0.94kph) at the same power
★ 38.7W saving at 40kph on the hoods, or a 304 second saving (+1.40kph) at the same power
