Pirelli SporTUBE Presta Tube - 29"

Butyl do as butyl be, as the old saying goes. A Pirelli SporTUBE Presta Tube doesn't do much other than hold air, but that's all you ever want your tube to do. You can take a gamble and go with a no-name job from the hardware store, or you can rock one of the most famous names in pneumatic tire history. The choice is yours.
