The Continental Tour 26 inner tube is a premium brand tube fitted with a high-pressure Presta valve. It’s ideal for city cyclists who need a reliable tube on their daily commute or for those on trekking/touring/mountain bikes where reliability is at the forefront of their spec list. It is made from butyl rubber and features seamless construction, with mould-cured vulcanisation, to ensure uniform roundness and improved reliability at the valve stem. A Continental inner tube makes a great replacement for damaged inner tubes which cannot be fixed with simple puncture repair. By fitting different types of tubes you can actively influence the handling characteristics of your bike with little effort.  Different wall thicknesses and the associated characteristics make this possible. Each and every Continental tube passes a stringent 100% quality control inspection.
