Using your Spurcycle bell is easy. Just give it a gentle tap, and it'll produce a loud sound to alert others. When installing, use the 2.5mm hex tool provided to attach it to your handlebar. Make sure it's firmly fixed. It can be installed on standard or oversize handlebars, whether they're aluminum or carbon. As for maintenance, if you have the raw metal finish, occasionally wipe it with a soft cloth to keep it clean. For the black DLC coating, it's quite durable, but avoid using abrasive materials. Keep it away from harsh chemicals. This bell is made in the USA and guaranteed for life, so enjoy using it worry - free.
