The WTB NanoAir TPU Inner Tube is a lightweight, compact alternative to traditional butyl tubes, designed for 29-inch mountain bike tires where reduced carried weight and space matter.
Made from TPU (thermoplastic polyurethane), the NanoAir tube is significantly lighter than standard butyl options while remaining durable enough for trail and XC use. Its compact packed size—approximately one-third that of a conventional tube—makes it easy to carry in a pack or saddle bag. Each tube includes glueless TPU patches for quick repairs on the trail, and the 48 mm Presta valve provides compatibility with a wide range of rim profiles.
