Specialized Thorn-Resistant Schrader Valve 700c Bike Tube

Ditch those thorns and shred the path! Specialized's Thorn-Resistant Schrader Valve 700c Bike Tube seals off any worries of your road bike getting snagged on debris or "goat heads." No roadie should stress about punctures -- these awesome tubes will keep you rolling!

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.
