Description: Save your speed during the tour with this easy-to-mount speed sensor. No magnets or other accessories are required. The sensor is quick to install and easy to maintain. It's also easy to use on a variety of bikes. The speed sensor 2 is mounted on one of the wheel hubs. Set the wheel size manually in Garmin ConnectTM or self-calibrate with an Edge® bike computer or compatible Garmin device. Once set up, you'll always get accurate speed and distance data - even without pairing with a Garmin product. ANT+® connectivity and Bluetooth® Low Energy enable synchronization with Garmin Connect and other training apps, compatible devices, and fitness equipment. This gives you extensive data for indoor training and outdoor tours. The speed sensor 2 automatically stores the distance for each ride and can therefore be used when planning service intervals.
