Lighter, smaller, stronger—what more do you want from a bike tube? Tubolito is a new alternative to a century old product. This new tube is twice as strong as a standard butyl rubber tube, meaning fewer punctures and more time for riding. They are also less than half the weight and a fraction of the physical size of a normal tube. Not only do you save on space, the reduced weight of two tubes and a spare gives you much less weight resistance for those never ending hill climbs. The Tubolito is crafted from a single piece of thermoplastic polymer, resulting in one overlapping joint, and features a removable valve on select models.
