Introducing CycleOps PowerCal, the worlds' 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 CycleOps and the University of Colorado Boulder have identified patterns which can correlate an athlete's heart rate to power across all real world conditions. We've 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 our PowerTap. Yes, it's a great tool, is incredibly easy to use, and is compatible with any existing ANT+ compatible display. Simply pair it to your display, and off you go!
We're all 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.
Cycleops are world famous for producing high quality cycle trainers. However, the company origins weren’t in cycling, believe it or not they started with producing curtain rods! The story goes that the Graber brothers sold their window products company and needed something to do. They experimented in their garage and came up with a best-selling bike rack. In 1989, Chris and Sara Fortune purchased the company when it was selling 80,000 bike racks a year. In 1990, a high-end brand of bike rack was launched, branded as “Saris.” Today Saris is a leading supplier to the bicycle industry in over 30 countries. The company expanded in 1999 by acquiring the Cycleops brand of bike trainer. As usual they set out to improve on the design and by 2001 they created a new trainer frame and in 2002 they launched the world’s first progressive resistance Cycleops magnetic trainer. It was in 2001 that they heard about a hub that could measure power output and they jumped at the chance to bring this product to cyclists. They bought the company that invented Powertap and started a new round of Cycleops cycling innovations.
