The PowerCal is the world’s first-ever power meter calculated from heart rate. At the time of its release, it was an incredible innovation combining two important training metrics: heart rate and power. And after all these years, the PowerCal remains as one of Powertap's most popular products, and for good reason—athletes of all kinds trust it ride after ride.
