WTB NanoAir TPU tube 29 2.5-3.0 FV 48 mm

29×2.5-3.0” FV 48 mm Lighter, more compact, and more durable. Yes, you get all three. WTB introduces the NanoAir TPU (thermoplastic polyurethane) tube. It’s compact and packs down to one-third the size of a traditional tube. Just think of all the extra things you can fit in your pack: a drink, snacks, maybe even a snack for that friend who always forgets one. TPU tubes are durable, and thanks to their special construction/material layup, they last longer than traditional butyl tubes. Having one of those “days” and you’re stumbling over thorns and getting another puncture? Don’t worry, we’ve added a few extra TPU patches to keep you moving.
