Tubolito S-TUBO CX/GRAVEL Disc Brake Only : 700x30-47c 42 mm

Inner tubes are old hat in the cycling world: they've remained largely unchanged for decades. However, the fine folks at Tubolito have gone out of their way to update the most overlooked part of a bicycle. Made from a unique thermoplastic polyurethane, they've created an inner tube that's 2/3rd's the weight of a standard butyl tube with twice the puncture resistance.

The 35 grams lightweight S-Tubo-CX/Gravel All is the ideal spare tube for all 700C and 650B tires from 30 - 47 mm width due to its very small packed size. However, it is not only a savior in need but can be perfectly used on a daily basis as it is still as robust as standard rubber tubes. Leftovers of tubeless liquids do not do any harm to it. Given its low rolling resistance it can also be the decisive advantage at competitions. Available with 42 mm (35 grams) and 60 mm (36 grams) Presta valves and suitable for disc brakes only.
