Race it hard or just head off the beaten path. The Strada Bianca combines Challenges 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 clincher combines a supple, 260TPI SuperPoly casing with natural rubber tread for long distance comfort, confident cornering, and quick handing. 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.
