Using these pedals is easy. Just mount them on your bike following the standard installation process. Make sure to check the tightness of the pedals regularly to avoid any safety issues. When riding, you'll notice the great grip from the hex traction pins, which helps you control your bike better. As for maintenance, keep the pedals clean. After a muddy ride, wash them with mild soap and water. Dry them thoroughly to prevent rust. The bearings are of high - quality, but if you feel any unusual noise or resistance, it might be time to take them to a professional bike mechanic. Also, make sure to use the right size for your shoes. The small size is good for US sizes 5 - 10 and EU sizes 37 - 43, so pick the size that suits you best for a comfortable ride.
