Using your AS3 Performance gear lever is straightforward. It's a direct replacement for your OEM lever, so just remove the old one and install this new one. Make sure it's securely in place before you start using it. When riding, the knurled grooves on the tip will give you a great grip, allowing for smooth gear changes.
As for maintenance, keep it clean. You can use a mild cleaner and a soft cloth to wipe it down. Check the spring - loaded tip regularly to ensure it's working properly. If you notice any signs of wear or damage, it's a good idea to get it inspected. Remember, this gear lever comes with a 12 - month warranty, so if there are any issues within that time, reach out for support.
