Race it hard or just head off the beaten path. The Strada Bianca combines Challenge’s proven herringbone tread pattern with larger volume and gravel specific construction to take you comfortably over less-than-perfect surfaces. This is the tire for rough roads, packed dirt, and most dry gravel surfaces. This handmade tubular combines a supple, 1000+ TPI Sealed Silk casing with natural rubber tread, and a seamless latex inner tube for improved comfort, 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 PPS2, a combination of our sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures.
