Using your new AS3 Performance rear sprocket is easy. Just replace your old sprocket with this one on your 2021 Rieju MR 300 Racing, Pro, or Ranger. Make sure it's properly tightened so it doesn't come loose during your ride. When riding, you'll notice how light it is compared to the old one, which can improve your bike's performance. As for maintenance, since it has self - cleaning grooves, it'll keep itself relatively clean. But it's still a good idea to give it a quick clean after a long ride or when it gets really dirty. Use a mild cleaner and a soft brush to avoid scratching the anodised finish. Also, keep an eye on the teeth for any signs of wear. If you notice anything unusual, like teeth starting to break or wear down quickly, contact the UK company that offers the 12 - month warranty. With proper use and care, this sprocket will serve you well for a long time.
