Specialized sv tr tube black 20 x 1.5-2.3

We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, theres 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), its actually thinner in order to reduce weight. This way, you dont have to sacrifice performance in the name of protection.
