Developed to fit in any small pocket, the lightweight S-Tubo-CX/Gravel tube is the ideal spare, and more. Not only a savior in need, the tube can be used on a daily basis as it's still as robust as standard rubber tubes, but with a lower rolling resistance for an advantage over the competition. Leftover tubeless liquids do not do any harm to it as well.
