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 Schrader 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.

We're not afraid to say it—our Airlock Presta Valve Tubes are the best performing, self-sealing bicycle tubes available on the market. 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 greater protection. - Non-toxic, non-separating formula. - Works continuously to prevent slow leaks. - Homogenous design prevents puddles.

To keep your Avid brakes functioning properly, check your pads for wear and replace them when necessary. Organic compound pads are softer for quieter braking and increased modulation, while metallic pads dissipate heat better and last a bit longer. Two pads, one retraction spring and a mounting bolt are included (enough for one brake) in each pad set. And, choose an aluminum backing plate if you're really counting the grams.
