Using these RockShox MTB front fenders is super easy. First, grab the four zip ties that come with the fenders. Then, find the right spots on your RockShox fork to attach the fenders. Wrap the zip ties around the fork and the fenders tightly to secure them. Make sure they are firmly in place before you hit the trail. When it comes to maintenance, after each ride, it's a good idea to clean the fenders with a damp cloth to remove any mud or dirt. Check the zip ties regularly to ensure they haven't loosened. If they have, just tighten them up a bit. Also, keep an eye on the fenders for any signs of damage. If you notice any cracks or breaks, it might be time to replace them. With proper use and care, these fenders will serve you well for a long time.
