Using this BMX chain breaker is a breeze. First, drop your chain into the breaker. Then, hold firmly onto the oversized handle. This handle is not only easy to grip but also has a hidden compartment. You can use it with most regular and half - link chains. If you want to use it with an Odyssey Key Chain, you'll need to buy an adapter separately. When using, make sure the chain is properly placed to avoid any jams. After use, keep it in a dry place to prevent rust. Wipe it clean regularly to maintain its performance.
