Using this brake disc and caliper guard is easy. Just replace the front wheel spacer with the provided aluminium bracket. The plastic guard will then fit snugly around the front brake disc and caliper. When riding, this guard will protect your brake components from dirt, rocks, and debris. Note that it only fits specific models, so double - check your bike's compatibility before installation. For maintenance, clean the guard regularly with a mild soap and water. If the plastic guard gets damaged, you can easily replace it. Keep it in a dry place when not in use to prevent corrosion of the aluminium bracket.
