Silca Inner tube Silca Ultimate 24-43mm 50mm

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