Using these grips is easy. First, take the Knuckleduster grip with the tapered internal sleeve. Tap it onto your handlebar until it's fully engaged. Then, use the single - bolt lock - on clamp to secure it. When riding, you'll notice how well your fingers fit into the grip, giving you great control. For maintenance, clean the grips regularly with a mild soap and water solution. Avoid using harsh chemicals as they might damage the TRC rubber blend. If you're riding in very wet conditions, dry the grips thoroughly after use to prevent any long - term damage. Also, check the single - bolt lock - on clamp periodically to make sure it's still tight and the grip is secure on the handlebar.
