The PowerTap PowerCal heart rate strap is the world’s first power meter calculated from a heart rate. Most pro riders will use power meters to determine the effort they put through the pedals. They also use a heart rate monitor to measure the physiological impact of that effort.
However, power meters are still luxury items for those with the bank balance to afford it. For many of us, we simply don’t have access to that power data to refine and hone our riding performance. The PowerTap PowerCal strap actually translates heart rate data in power-based training Watts, Kilojoules and peak power etc.
This is the culmination of intensive testing and research by PowerTap engineers and the University of Colorado, Boulder.

You will need a wireless computer to sync with other devices. Most wireless computers sync using 2 wireless technologies – ANT+ & Bluetooth Smart.
ANT+ enabled devices to talk to each other and present the information on a compatible device.
Bluetooth Smart is a low energy wireless technology designed for smart sport and fitness. The long battery life in sensors makes it ideal for regular use in cycling.
Always check your smartphone’s OS and 3rd party devices are compatible.
If you’re looking for something more versatile then cycle watches are a great alternative. You can still gather data from cycling sensors, but you can also gather data for different sports too. They are great for triathletes and those that do multiple sports.
You can easily transfer data from a road bike to a mountain bike, from running to swimming. There aren’t many outdoor exercises you can’t track.
Strava is perhaps the most well-known cycling App / software around. All you need is to record your cycling with a compatible GPS device, upload it to Strava and then you can analyse your data. You can compare your performance to previous efforts, your mates and even pro riders - all of this, for free.
All Garmin computers and devices will work with Garmin Connect. This is an online service that allows you to analyse your performance data, and share it with your friends. Reports show you how you’re progressing and you can use the calendar feature to plan your training sessions over time.
