Go ahead and stray from the beaten path.

Versatility and comfort were two of the most important objectives in mind when Challenge began developing its Strada Clincher Tire. With its 25mm-wide profile and ultra-gripp'y tread pattern, the Strada delivers on all fronts. It's ideal for your tarmac rides, gravel adventures, and even a few cobbled stretches here and there. And with its reliable 'open tubular' clincher construction, the Strada provides a smooth ride regardless of your preferred road surfaces.

Challenge accomplished this versatility using its handmade, highly puncture-resistant, and lightweight Super Poly casing. With 260 threads per inch (TPI), you receive a remarkably supple ride -- and it's a difference that you'll feel the first time out. On top of the casing, Challenge added a belt of corespun polyester. Essentially, this means that the casing fibers are made by twisting staple polyester fibers around a central filament core, creating one yarn from multiple fibers. As a result, the material is between 40 and 50% stronger than typically spun materials, while retaining a similar, if not lower, overall weight. This second layer is what Challenge calls its PPS (Puncture Protection System), and it's specifically made from the tightly woven polyester material to preserve the casing's supple feel.

For the tread, Challenge used its file-like herringbone pattern. This low-profile pattern perfectly blends speed and grip. The tread was applied using Challenge's proven hand-glued method, which involves mounting and then inflating the casing on a wheel. Only then does Challenge carefully glue on the tread layer. As a result, the tread isn't put under tension when you inflate the tire on your wheel, and that lack of tension leads to lower rolling resistance, added grip, and increased comfort.

At the bead of the tire, the Super Poly casing is wrapped around Aramid fibers. Essentially, Aramid is a strong material, which is why it's commonly used in bulletproof vests. For the Strada clincher, this equates to added cumulative strength and durability.

The Challenge Strada is available as a 700c x 25mm open tubular tire (clincher) and in the colors Black/black and Black/tan. Each tire weighs in around 260g without tubes.
