BOULDER, CO (BRAIN) — Challenge is introducing a new line of road tubular and clincher tires named for the famous white gravel roads of Tuscany, Italy, and the annual Eroica road race there.
Challenge's Strada Bianca models are based on the company's Paris-Roubaix models, but with more volume. While the Roubaix tires have a 27 millimeter profile, the Strada Biancha is 30 millimeters. The new tire models also have a double layer of puncture protection, a herringbone tread and a 260 TPI casing.
The Strada Bianca is available in classic black with tan sidewall or all black. Suggested pressure is 55-115 psi. The clincher version weighs 300 grams and retails for $76. The tubular weighs 285 grams and retails for $109.
