Next-Gen TPU Material Innovation: Engineered from Thermoplastic Polyurethane (TPU), delivering an incredibly tough, puncture-resistant barrier that shields against pinch flats and punctures while shedding up to 70% of the weight of old-school butyl rubber tubes.
Ultra-Compact Space Saver: Folds down into a tiny fraction of the size of a standard tube, making this 2-pack the ultimate lightweight, pocket-sized emergency backup solution for your saddle bag or jersey pocket.
45mm Heavy-Duty Metal Presta Valve: Outfitted with a durable 1.77-inch (45mm) metal Presta valve stem that resists tearing at the base and stands up perfectly to high-pressure pump clamping.
Removable Valve Core Utility: Features a fully removable core design, allowing you to seamlessly thread on valve extenders for deeper aero rims or easily add liquid tire sealants for an extra layer of puncture defense.
Universal High-Volume Trail Fitment: Specifically tailored to stretch and conform cleanly across 26-inch, 27.5-inch, and 29-inch mountain or gravel bike tires with widths ranging from 1.9 to 2.5 inches.
