Using the Topeak BarXtender is easy. First, decide where you want to place it on your handlebars or stem. Then, securely attach it using the provided tools. Make sure it's tightened well to prevent it from moving during your ride. When adjusting the position, take your time to find the most comfortable and convenient spot for your accessories. As for maintenance, periodically check the attachment points to ensure they're still tight. Clean the BarXtender with a mild soap and water to keep it looking good.
