A USB ANT+ dongle is what receives the signals from the sensors on your bike or your trainer and transmits them to your computer and Zwift.
Getting an ANT+ dongle for PC or Mac is easy. Head on over to the Zwift Shop to pick up a handy starter pack, or check out our friends at Performance Bicycle or Wiggle! Any USB2 ANT+ dongle will work. We recommend the USB-m as it has proven to have the best signal reception in the lab. Make sure you pick up a USB extension cable to get the dongle closer to your equipment and prevent dropouts.
If you're planning on using ANT+ on iOS, you have a few different options to bridge the signal:
- The Viiiiva Heart Rate Monitor
- The Wahoo ANT+ key in combination with Lightning to 30-pin adapter
- The NPE CABLE
NOTE! Resistance control for smart trainers isn't supported over ANT+ at this time.
