Jump on your bike and pedal on out - don't forget to pack the Thorn-Resistant Presta Valve 29" Bike Tubes for your ride! Specialized designed these tubes to slay thorns & spines of all kinds, so you can bask in the beauty of the ride without a single prick. 

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.


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