Challenge Strada Bianca Open Road TyreDesigned for Gravel racing. Proven Paris-Roubaix tread pattern. PPS-2 double puncture protection strip. Low rolling resistance with increased casing volume, achieving a new level of control, puncture resistance and comfort. Giving you fast rolling and cornering, this world-class tyre is a perfect upgrade for riders who want maximum control in all riding conditions. Features: Size: 700 Tyre Width: 30mm Internal Rim Width: 15-19mm TPI: 260 Bead: Aramid Casing: SuperPoly Flat Protection: Double PPS BAR: 6-9 PSI: 90-130 Weight: 355gTechnologies: Challenge Handmade Clinchers (HCL): Our Handmade Clinchers are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around an aramid bead to form a tire that fits on a clincher rim. The HCL is moulded flat, not in a horseshoe like a TLR or VCL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A tubeless tire is moulded in a U-shape to make the sidewalls rigid, so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The tubeless tire's stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
