With this heart rate strap you can easily collect data from other ANT+ bike sensors, such as a cycling computer, speed and cadence sensor. You can then easily transfer this data to your iOS or Android smartphone or tablet through Bluetooth. This gives you all the data in one place. Perfect to use in combination with your cycletrainer. This makes the use of an ANT+ dongle unnecessary.

The Viiiiva has the so-called beat-to-beat measuring system, an optimised measuring system for registering your heart rate. With this new system, the 4iiiiii Viiiiva is up to 10x more sensitive to heart rate capture than other heart-rate bands. This ensures a very precise heart rate registration. Ideal for cyclists who have high demands for their cycling attributes. In addition, the Viiiiva offers a high level of usability. The Viiiiva also has a good memory. You can now collect up to 65 hours of training data on your Viiiiva.
