Using these pedals is easy. Just attach them to your bike following the standard installation process. Make sure to check that they are tightened properly before you start riding. When it comes to shoe selection, refer to the recommended shoe sizes to get the best fit and performance. As for maintenance, keep the pedals clean by wiping them down after each ride. If they get wet, dry them thoroughly to prevent rust. The bearings are high - quality, but it's a good idea to have them checked periodically by a professional bike mechanic. Also, if you notice any loose traction pins, tighten them right away to ensure your safety on the road or trail.
