Shop all Specialized | Shop all Tubes
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. We then make the inner side, the part against the rim, thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. We didn't stop there, however, as these tubes also feature our 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.
