The new Tacx sensor measures speed and cadence and sends data wirelessly via ANT+ and Bluetooth smart technology to devices connected to the sensor. It makes no difference whether it is a smartphone, tablet, sports watch, GPS device, bicycle computer or Tacx home trainer. There are many devices that record training data either via ANT+ or Bluetooth, but not via both communication techniques simultaneously, or optionally. The Speed & Cadence Sensor from Tacx makes this possible. This allows you to record your sporting performance in the way you like best. Connect the sensor simultaneously via Bluetooth to your smartphone and/or via ANT+ to your sports watch, for example. Or simply and quickly control your speed and cadence on your smartphone via well-known sports apps such as Endomondo and Strava. For the Speed & Cadence Sensor you need Bluetooth 4 or higher.
