Challenge Strada Bianca Pro 36c Open Tubular
It’s hard to keep Challenge Tires’ model names straight, but the new 36mm Strada Bianca Pro open tubular is the company’s biggest knob-less open tubular and the one we’re most excited about.
Sure, the company offers a tire named after the Queen of the Classics itself, the Paris Roubaix (formerly Parigi Roubaix), but that model’s width, at 27mm, is quite narrow even by today’s road standards. The newly-released 36mm version of the Strada Bianca Pro (formerly called Eroica) is named after the famed Strade Bianche race filled with 50k of dirt roads—likely surfaces conditions closer to what your own spring classic will include.
The Strada Bianca is available in tanwall or black. Our 36mm test tire measured out to be 34mm on a 17mm rim (35 psi). Although a tad undersized, that generous volume, paired with the open tubular, 260 tpi construction, makes for a comfortable ride. When you hit the bumps or cobbles, the high volume tire transforms into what’s best described as a “muted” ride. Bumps and road noise fade away.
The herringbone tread has little to offer for grip on loose gravel or wet surfaces, but it’s similar to what many professional classics hunters use. With lower tire pressure, you’ll find grip is surprisingly good. Pair with a latex tube for lower rolling resistance and pinch protection.
Our test tire was 20 grams lighter than spec at 353 grams.
