Tacx Speed and Cadence Sensor
This sensor measures your speed and cadence and transmits this information wirelessly via dual technology to the devices it is linked to. Because it can communicate via both channels, you can link it via Bluetooth® to your smartphone and via ANT+ to your sports watch.
Do you have a basic trainer? Then you can use this sensor to train with your smartphone or tablet! You train on the basis of virtual power with the Tacx Training app, Tacx Cycling app, Zwift or TrainerRoad.
The Tacx sensors are compatible with devices that have:
Bluetooth Smart* / Bluetooth 4 and higher
*If you have a different Bluetooth version and you want to link the Tacx sensors to your smartphone or tablet, you can use a receiver developed specially for that purpose. For an Apple (iPhone) device, use the Wahoo ANT+ dongle. For devices with a micro USB port, use the Tacx ANT+ Dongle micro USB.
