Using these pedals is easy. Just attach them to your bike's crank arms. Make sure to tighten them properly to avoid any wobbling. When riding, place your feet firmly on the pedals for maximum power transfer. As for maintenance, keep the pedals clean by wiping them down after each ride, especially if you've been in wet or muddy conditions. Periodically check the axle for any signs of wear or looseness. If you notice any issues, it's best to have them inspected by a professional bike mechanic. Also, avoid using harsh chemicals on the pedals as they can damage the carbon composite and stainless steel materials.
