Using this front brake disc guard is easy. Just replace the front wheel spacer on your 2017 - 2023 Beta 250 Xtrainer or 2015 - 2023 Beta 300 Xtrainer with the mounting bracket that comes with the guard. Once it's installed, your brake disc will be protected from rocks and debris. When riding, the vents on the guard will help keep the brake caliper cool, which means better braking. As for maintenance, check the guard regularly for any signs of damage. If it gets dirty, you can clean it with a mild soap and water. And if the guard gets too worn out, you can easily replace it as replacement guards are available. Remember, the guard you receive is exactly the one shown in the picture, so you know what to expect.
