The tube is for a 18 inch rear wheel. All enduro and motocross bikes are nowadays supplied with inner tubes in the tyres. These tubes are often very thin (1.4 mm) and you easily get a flat tire. Our X-GRIP tube 18″ Standard Duty is made of butyl and is 2.5 mm thick. Butyl is known for its excellent air impermeability.
