Using the Topeak BarXtender is a breeze. First, decide whether you want to install it on the bar or the stem. Once you've made that choice, attach the BarXtender securely using the appropriate tools. When adding accessories like bells, computers, lights, or horns, make sure they are firmly fixed to the BarXtender. As for maintenance, keep it clean by wiping it down regularly with a dry cloth. Avoid using harsh chemicals as they might damage the finish. If you notice any loose parts, tighten them up right away to ensure safe use.
