Inner tube Nanoair TPU

Lighter, more compact, and more durable. Yes, you get all three. WTB presents the NanoAir TPU (thermoplastic polyurethane) tube. It’s compact and only a third of the size of a traditional tube. Just think of the extra stuff you can fit in your bag; a drink, some snacks, maybe even a snack for your friend who always forgets one, yes, you know them. It’s light. We mean really light. 60% lighter than the paperweight (ahem, ahem) you carry. "But it’s so light," you say, "how is it better than my paperweight tube?" Don’t worry, these TPU tubes are tough, with a special construction/layer of materials, they’re more durable than traditional butyl tubes. You're having one of "those days," and you’re crawling through a thicket, and you get another puncture? Don't worry, we've included some extra TPU patches to help you keep going.
