Using your AS3 Performance Factory Series rear sprocket is easy. First, make sure your bike is turned off and on a stable surface. Remove the old sprocket and then carefully install the new 52T sprocket. Ensure it fits snugly and tighten all the bolts properly.
When it comes to usage, this sprocket is great for enduro riding, but try to avoid extremely rough impacts as much as possible. It's more durable than aluminium sprockets, but still, don't push it to the limit.
For maintenance, regularly clean the sprocket with a mild detergent and a soft brush. Check for any signs of wear, like loose teeth or excessive scratching, every few rides. If you notice any issues, contact the UK company's support team as it comes with a 12 - month warranty. This way, your sprocket will serve you well for a long time.
