The Dune is the Belgian’s secret skill-building tire. Like the Chicane, this tire is a super fast rolling sand tire that also works incredibly well on frozen courses. The small shoulder knobs are intended for riders with great bike handling skills. This handmade tubular combines a supple, 320TPI sealed corespun cotton casing with natural rubber tread, and a seamless latex inner tube for improved grip at lower pressures, confident cornering, and quick handing. The latex tube is lighter, thinner and more flexible than a butyl tube, increasing your comfort, lowering your rolling resistance, and helping to prevent flats. The tube also includes a removable core Presta valve. This tire includes PPS, a Puncture Protection System placed between the tread and casing to increase resistance to punctures.
