Using the Burley Thru Axle is a breeze. First, make sure your bike has a 12mm thru axle. Then, install the adapter following the simple instructions. It allows you to attach a kid, cargo, or pet trailer to your bike, making your rides more fun and useful. Before purchasing, it's important to double - check the thread pitch and hub length with your bike's manufacturer or local bike shop. To keep it in good shape, clean it regularly with a mild soap and water. Avoid using harsh chemicals that could damage it. Store it in a dry place when not in use to prevent rusting.
