Using the SKS Mud-x Downtube Mudguard is a breeze. First, take the elastic rubber bands and route them over the downtube of your bike. Then, hook them onto the dirtboard. You don't need to add any fastenings to the frame. When riding, this mudguard will do a great job of keeping dirt, stones, and water spray off you. As for maintenance, it's simple. Just clean it with mild soap and water after each dirty ride. Make sure to check the rubber bands regularly for any signs of wear and tear. If they start to look old or loose, it might be time to replace them. Also, keep the foam rubber pad clean to ensure it continues to protect your bike from scratches.
