Aerosensor is a portable real-time cycling aerodynamic drag measurement device with unrivalled accuracy. Based on a patented¹ probe design it gives peerless repeatability in practically all wind conditions.

The device connects wirelesly to the bicycle speed sensor and power meter using Ant+. Combing this data with its own measurements of dynamic pressure, wind yaw angle, and altitude it calculates the aerodynamic drag coefficient (CdA), and transmits that to a Garmin cycle computer for display and logging using our CIQ app.
