Note: Delivery includes the PowerCal Bluetooth Smart Heart Rate Strap, not the ANT+ version, as it is shown on the images.
Introducing PowerTap PowerCal, the world's first-ever power meter calculated from heart rate. For years there has been a widely recognized correlation between power and heart rate. In a lab one can predict power output or intensity by knowing heart rate, and vice versa. But once you leave the lab and enter variables such as hills, wind and fatigue, the relationship gets a bit trickier. This is why many cyclists and triathletes use both a heart rate monitor and a power meter in training.
Through the use of these tools and the analysis of tens of thousands of power files over the years, the experts at PowerTap and the University of Colorado Boulder have identified patterns which can correlate an athlete's heart rate to power across all real world conditions. PowerTap utilized this knowledge to create a technology which provides power based on this correlation; in the real world and in real time.
No, it's not as precise as the PowerTap hubs. Yes, it's a great tool, is incredibly easy to use, and is compatible with any existing BT compatible device. Simply pair it to your display, and off you go!
PowerTap is familiar with the key difference between a power meter and a HR monitor: that HR is a response to the work you're doing, whereas power is the actual work. The algorithms in PowerCal translate heart rate data into the vernacular of power-based training- watts, kilojoules, peak power, etc.
And at this low price, it could be one of the best investments you make in your training. So if you're ready to take your performance to the next level, let PowerCal help get you there.
