Using these fenders is a breeze. First, find the eyelets on your bike. Then, use the stainless - steel hardware provided to mount the fenders securely. The hardware can be replaced if it gets worn out. When riding, the fenders will do a great job of protecting you from mud and debris. However, if you notice any rattling, check the double rear stays to make sure they're properly attached. To maintain your fenders, regularly clean them with a mild soap and water. Avoid using harsh chemicals as they may damage the anodized aluminum or the polypropylene mudflaps. If debris gets caught between the fender and the tire, the safety release tabs will let the wheel keep turning, but you should stop and clear the debris as soon as it's safe to do so.
