Desert Protection Schrader Valve Tube - 20 x 1.5-2.3

Nothing in the cycling world is more infuriating than flat tires. With Desert Protection Schrader Valve Tubes, you can minimize, if not eliminate, flats caused by debris, thorns, or other hazards that halt your rides.The tube is designed with asymmetrical construction: thicker on the outer side (against the tire) to stop debris from puncturing through, and thinner on the inner side (against the rim) to reduce weight. This design allows you to maintain performance without sacrificing protection.These tubes feature Airlock sealant that coats the tube for permanent protection against punctures. The sealant is designed to work continuously to prevent slow leaks, so you won't have to worry about flats when riding over debris. The homogenous design prevents sealant pooling, ensuring the tire and tube combo rolls smooth and even without needing to shake the tire.
