Using these pedals is a breeze. Just step on the flat part for casual riding or clip in your shoes for more intense rides. Make sure your shoes are compatible with the included premium brass cleats. When adjusting the traction pins, use a proper tool and set them according to your preference and riding conditions. There's no weight limit, so riders of all sizes can use them. To maintain these pedals, clean them regularly with a mild soap and water. Avoid using harsh chemicals. Check the bearings and seals periodically for any signs of wear. The 5 - year warranty gives you peace of mind, but if you notice any issues, contact the manufacturer right away.
