Using your new AS3 rear sprocket is easy. First, make sure your bike is turned off and on a stable surface. Remove the old sprocket carefully, following your bike's manual. Then, install the new 49 - tooth sprocket in its place, ensuring it fits snugly. When riding, you'll notice the difference in performance due to its lightweight design. As for maintenance, regularly clean the sprocket to keep the self - cleaning grooves working effectively. You can use a mild soap and water solution and a soft brush. Check the sprocket for any signs of wear or damage after every few rides. If you spot any issues, contact the UK company for assistance as it comes with a 12 - month warranty. And remember, the sprocket you got is exactly what's shown in the picture, so enjoy its smooth anodised finish and AS3 branding.
