The WTB NanoAir TPU Inner Tube is a lightweight, compact alternative to traditional butyl tubes, designed for road and all-road riders who want to reduce rotating weight and carry a smaller spare.
Made from TPU (thermoplastic polyurethane), NanoAir tubes are significantly lighter than standard butyl tubes while maintaining durability for real-world riding. Their compact folded size makes them easy to stash in a saddle bag or jersey pocket, and each tube includes glueless TPU patches for quick repairs when needed. The 48 mm Presta valve provides broad compatibility with modern rim profiles.
