Power measurement helps you ride faster, train better, and race smarter. But power doesn’t tell you everything. Another metric, aerodynamic "CdA" (coefficient of drag times frontal surface area), is the key to riding fastest in the wind. Simply put, the lower your CdA, the more aero you are. And watt-for-watt, the more aero you are, the faster you go. Elite cyclists improve CdA through expensive and time-consuming wind tunnel and velodrome testing. Now, Velocomp’s new AeroPod lets you improve the aerodynamics of your ride position, equipment, and clothing, on your normal bike routes. Real-time CdA from AeroPod is like having a wind tunnel on your handlebars!
