Using your Spurcycle bell is super easy. Just give it a light tap, and it will emit a loud, long - lasting sound to alert others. When installing, use the 2.5mm hex tool to attach it to your handlebar. Make sure it's firmly in place so it doesn't rattle. As for maintenance, since it's made of premium brass and stainless steel, it's quite durable. But to keep it looking its best, wipe it down with a soft cloth regularly. If it has the black DLC coating, avoid using abrasive cleaners as they may scratch the finish. And remember, this bell is made in the USA and comes with a lifetime guarantee, so you can enjoy using it worry - free.
