Using the Garmin Rally XC100 Single - sensing Power Meter Pedal Set is easy. First, make sure your pedals are properly installed on your bike and that the Shimano SPD cleats on your shoes fit well. Then pair the pedals with a compatible device, like a cycling computer. Once paired, you can start your ride and immediately see accurate power and cadence data. As for maintenance, keep the pedals clean after each ride, especially if you've been riding in muddy or wet conditions. Use a soft cloth to wipe them down. Also, check the battery regularly. If you notice any issues with the power measurement or the pairing, try resetting the pedals and the device. And always follow the manufacturer's instructions for long - term use and storage.
