On the bike 70-90% of a riders power output will go to overcome the resistance of the air. Positioning is extremely important for cyclist to be able to maintain a low drag while still producing sufficient power.. Any rider can get into a very aero position and get good numbers in a wind tunnel, but if he/she cannot produce efficient power there is no way they will reach their full potential on the bike. Along with drag measurement we use a Computrainer® to measure power output in Watts, cadence, wheel speed, and heart rate to determine if a position change helped or hurt the overall performance of the rider.
A2 offers a second data collection system that is dedicated to aerodynamic testing for the cyclist community. Features include:
o Precision balance: ± 0.5%
o Data projection system providing rider real-time drag & Computrainer® data on floor of test section
o Proprietary data collection system with integrated Computrainer®
o Aerodynamic drag in: CD , CDA, Grams & Aero Wattage (Grams & Watts Corrected to Std NACA Day)
o Power output
o Heart rate
o Cadence
o Wheel speed
o +/- 25 degree yaw
o Spinning wheels (with and without rider)
o Digital full motion cameras with recording
o Digital position overlay system
o All run data is exported to Excel format for ease of understanding and additional analysis by the customer
o Smoke testing
