The second speed sensor can be connected to either wheel hub. You have the option to input wheel size in our Garmin connect online community or calibrate with an edge cycling computer or compatible Garmin device.
Once configured, you will receive precise speed and distance readings consistently, even without a head unit.
Ant+ connectivity and Bluetooth Low energy technology allow for syncing to Garmin Connect and other training apps, compatible devices, and fitness equipment for improved data during indoor and outdoor rides.
The odometer function keeps track of your distance to assist in scheduling bicycle maintenance.
