The Continental 28x1 3/8/ 32-622 / 47-622 Tour 28 Hermetic Plus inner tube with a 40mm DV17 Dutch valve is an ideal inner tube for your bike. Made of high-quality butyl material, this inner tube ensures less maintenance and greater safety. Thanks to its special rubber compound, the inner tube retains its pressure up to three times longer than a standard inner tube, meaning you need to pump less often. Moreover, the rubber in this inner tube is much stronger, significantly reducing the risk of punctures. This inner tube is suitable for trekking bikes, hybrid bikes, electric bikes, and city bikes.
