ONTRACK 29 inch bicycle inner tubes are made with high-quality materials that are resistant to punctures, abrasions, and tears. The larger size reduces rolling resistance by providing a wider contact patch with the ground. The larger diameter of the tubes allows for a smoother ride, fewer punctures and more stable handling, especially in rough terrain. Can be used in a wide range of bikes such as mountain bikes, fat tire bikes, and touring bikes.
