Strada Bianca | Challenge Tires

The Challenge Strada Bianca Clincher tire is designed for bumpy, rough roads. Not only is it one of the toughest tires in Challenge’s lineup, it also provides one of the smoothest rides, coming in at 33mm & 36mm. The Strada Bianca’s casing is a handmade, puncture-resistant, lightweight SuperPoly material. With 120 threads per inch (TPI), you’ll immediately notice the supple ride. On top of the casing, Challenge added a belt of CoreSpun polyester, made by twisting fibers around a central filament core, creating one yarn from multiple strands.

The material is 40 to 50% stronger than typically spun materials, while retaining or even reducing overall weight. This is the PPS (Puncture Protection System) layer, and it’s specifically made from the tightly woven polyester material to preserve the casing’s supple feel. The tread pattern – the Paris Roubaix Herringbone – is among Challenge’s most versatile. Available in black or in a gumwall.
