Using these Ultegra PD - R8000 pedals is easy. Just step on them firmly when you're ready to pedal. For the best performance, make sure your feet are centered on the pedals. When it comes to maintenance, keep them clean by wiping off dirt and grime regularly. Avoid using harsh chemicals as they might damage the carbon composite body and stainless - steel plate. Store the pedals in a dry place to prevent rusting. Also, check the axle and other parts for any signs of wear or looseness every few rides. If you notice anything wrong, get them checked by a professional.
