We're not afraid to say it—our Airlock Schrader Valve Tubes are the best performing, self-sealing bicycle tubes available. That's because they feature our powerful Airlock sealant that coats the tube for permanent protection against punctures. Not only this, but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris. We even addressed the common issue of sealant pooling with a completely homogenous design, so the tire/tube combo will always roll smooth and even. - Airlock sealant for the best chance of reducing punctures. - Non-toxic, non-separating formula. - Works continuously to prevent slow leaks. - Homogenous design prevents puddles with no need to shake. - Will not dry out like the many other sealants.

For 29er tires, more than 100g per wheel can be saved with Tubo tubes compared to standard butyl tubes—and almost twice as much space when packaged. Their riding safety is twice as high as for standard tubes and offers maximum protection against a breakdown. The assembly is just as easy as standard tubes. Tubolito tubes are also a lightweight alternative to a tubeless setup. - 42mm valve length

Serfas replacement inner tubes are lightweight, durable, and affordable.

We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Presta Valve Tubes to combat pesky pricks of all shapes and sizes. Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. - Thicker construction on the outer side (against the tire) enhances puncture protection. - Thinner construction on the inner side (against the rim) maximizes weight savings.
