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. Compatible with devices that have:
- ANT+
- 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.
