Specialized Specialized sv tr tube black 29 x 1.75-2.4

Shed those thorns and get outdoors! Specialized's Thorn-Resistant Schrader Valve 29" Bike Tube makes sure you won't have a need to skid to a stop when riding over rubble or "goat heads". No mountain biker needs to stress about their reliable ride getting punctured - these awesome tubes will have your back!

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.
