Using these bike pedals is easy. First, make sure the 9/16' spindle fits your bike. Then, install the pedals onto your bike's cranks. You can adjust the 9 pins on each platform to your preferred height for better grip. When riding, place your feet on the large platform for maximum stability. Remember, these pedals are built for serious biking, so they can handle rough rides. But it's a good idea to check the pins regularly to make sure they're tight. To maintain them, clean the pedals after each ride with a damp cloth to remove dirt and grime. If you notice any signs of wear on the alloy body, it might be time to get them serviced. Enjoy your ride with these high - performance pedals!
