Using your AS3 7075 Aluminium 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 AS3 sprocket in its place. Make sure all bolts are tightened properly. When riding, the self - cleaning grooves between the teeth will help keep dirt and debris away, ensuring smooth operation. For maintenance, after each ride, it's a good idea to clean the sprocket with a mild cleaner and a soft brush. Check the bolts regularly to make sure they're still tight. If you notice any signs of wear or damage, don't hesitate to contact our UK - based company. Remember, your sprocket comes with a 12 - month warranty, so you can ride with peace of mind.
