Adhesive tire patches can quickly repair bicycle tires, making it convenient and fast to handle unexpected flats. Simple and practical design allows you to access the tools when needed, helping you remove the inner tube more easily and assist in the repair process. Suitable for road bikes, mountain bikes, cyclocross bikes, and other bicycles. These patches work on inflatable rubber items, wheelchair inner tubes, and motorcycle tires. To use: First, release all air from the tire. Use a tire lever to remove the inner tube. Locate the puncture, then use a metal file to roughen and clean the area around the hole. Apply the self-adhesive tire patch directly over the puncture, pressing firmly to ensure a secure bond. Made from foam material, the patches are small, lightweight, and easy to carry in a pocket or bag.
