Say goodbye to pesky thorns -- the Specialized Thorn-Resistant Schrader Valve Tubes will keep your journey as smooth as can be! Great for everything from kids and BMX to 20 inch wheeled e-bikes.

Don't let pricks stop you in your tracks-- these tubes are the perfect way to ensure that your rides stay beautiful and puncture free!Starting at the basis of the construction, Specialized 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.

FEATURES

• Thicker construction on the outer side (against the tire) enhances puncture protection.
• Thinner construction on the inner side (against the rim) maximizes weight savings.
