The WTB NanoAir TPU Tube is what happens when you take a hard look at that chunky butyl spare stuffed in your kit and say, enough. Made from Thermoplastic Polyurethane, it weighs in at just 35g for the 700x18/32 size, coming in around 60% lighter than a standard butyl tube and packing down to one-third the size. That means more room in your jersey pocket, your saddle bag, or your pack for things that actually matter on a long ride.
Beyond the impressive weight savings, WTB engineered the NanoAir with a special TPU construction and layup that makes it tougher than traditional butyl rubber, not just a pretty face on a gram scale. It also holds air better than butyl over time, so a tube you stash in your bag today will still be ready to go three months from now when you actually need it. A 48mm threaded Presta valve fits most modern rims without fuss.
Two glueless TPU patches are included right in the box, so if you flat and patch on the trail, you've still got a backup. This is the tube you grab when you want to go fast, go light, and still have a solid plan B tucked away.
Throw this in your saddle bag and forget it's even there until you need it. Whether you're deep into a gravel epic or keeping your weight-weenie XC setup honest, the NanoAir fits your 700c tire without adding bulk to your kit. Your tubeless setup is great until it isn't, and this is the smartest, lightest insurance policy you can carry.
