Description
Heart rate, speed and cadence are essential metrics for measuring cycling success and the Powertap PowerCal Bluetooth Heart Rate Strap & Speed/Cadence Sensor allows you to accurately and comfortably record your heart rate, speed and cadence during your ride.
Bluetooth SMART enabled, both the PowerCal and Speed/Cadence Sensor are easily linked to your Joules GPS+ head unit or other Bluetooth SMART enabled devices such as your smart phone, where both devices can provide live or post ride data using the Powertap mobile app.
With an elasticated adjustable strap, the PowerCal can be suited to fit any body shape, while the receptive pads help pick up a stronger signal from your heart for a better and more accurate reading.
