It's a party for two and the ANT+ Dongle and USB Cable are coming.
If your PC is running Windows 10, you can connect to Zwift using Native BLE. If you're running an older version of Windows or want to connect your ANT+ only sensors, you will need this ANT+ bundle to connect to Zwift.
Bundle includes an ANT+ dongle and a 10 foot extension cable.
ANT+ dongle plugs into the extension cable via USB 2.0.
USB cable plugs into your computer’s USB 2.0 port.
