The Felt was not a completely stock setup as noted below, and crank length was slightly different between the Tactical and IA10. Both bikes we setup up as close as possible for saddle position and angle, and pad stack and reach. The Tactical was tested against the Felt IA10, a bike with s similar MSRP. This interaction is largely removed during testing in the wind tunnel. This allows the interaction between a moving bike and rider to be re- introduced into the measurement of CdA. TAS calculates CdA in real-time as an athlete rides a bicycle on the velodrome. The only international level velodrome in the United States, VELO Sports Center is home to both ERO Sports and the Alphamantis Track Aero System (TAS), which provides real-time aerodynamic testing.
Used by aerospace to develop some of the most advanced planes and spacecraft in history, the tunnel has also played a huge role in cycling aerodynamics as its large test section, smooth airflow, and uniform velocity all equate to some of the best data collection available. Premier Bike paid for use of the wind tunnel testing, and a consultation fee to ERO Sports.Īlso known as the Low Speed Wind Tunnel (LSWT), The San Diego Wind Tunnel has been in operation since 1947. The tests were overseen by ERO Sports to insure both accuracy of the tests and the reported results. The following are results from aerodynamic testing of the Premier Bike "1.0" Tactical bicycle utilizing wind tunnel testing. Wind Tunnel Tests of PremierBike "1.0" Tactical TT/Triathlon Bike.
