The WTB NanoAir TPU Inner Tube is a lightweight, space-saving alternative to traditional butyl tubes, designed for riders running wider 700c tires on gravel, all-road, and endurance bikes.
Constructed from TPU (thermoplastic polyurethane), the NanoAir tube significantly reduces weight while remaining durable enough for regular riding. Its compact packed size—about one-third that of a standard butyl tube—makes it easy to carry as a spare in a saddle bag or frame pack. Each tube includes glueless TPU patches for quick roadside or trailside repairs, and the 48 mm Presta valve provides compatibility with a wide range of modern rim profiles.
