Using your AS3 rear sprocket is easy. First, make sure your bike is turned off and on a stable surface. Then, carefully remove the old sprocket and install the new one according to your bike's manual. When riding, you'll notice the smooth performance thanks to the self - cleaning grooves. As for maintenance, regularly check the sprocket for any signs of wear or damage. Keep it clean by using a soft brush and mild cleaner. Avoid using harsh chemicals as they can damage the anodised finish. If you have any issues, remember the product comes with a 12 - month warranty from the UK company. Enjoy a lighter and more durable riding experience with your new sprocket.
