Stay safe on your next ride around town with the Bell Sports 24 Self-Sealing Bike Inner Tube. Inside is a sealant that works quickly to seal up holes helping to prevent flats caused by punctures. This makes it easier to keep riding and reach your destination giving you time to change the tire later in your garage or workshop. The self-sealing inner tube is made with quality rubber and fits a range of tire widths. This makes it compatible with a variety of bicycle makes and models for greater versatility and easy installation.
