Challenge creates handmade Tubular and Open Tubular tires using an artisan process that allows the rubber to retain its natural properties. By avoiding the industry-standard vulcanization process, which requires extremely high heat, we provide tires with the superior grip, performance and comfort required by demanding professional athletes and everyday riders. Continuous research in sophisticated raw materials and production processes make us unique. Challenge offers top-end Silk and Cotton casings with the highest thread count possible, plus puncture protection and advanced natural rubber compounds for suppleness, safety and strength.
Challenge tires are produced by hand in Thailand close to sustainable rubber plantations. Here the skilled staff create tires using processes that have been honed for twenty-five years in Thailand and for decades prior when the factory was in Italy. The Brauns family, long time activists of the cycling industry, purchased the factory in 1990 to support their growing customer base. Wanting to do more with our growing expertise, the family decided to create their own brand and Challenge was born in 2003. Though we still produce tires for other brands, our primary focus now is on developing our own line of handmade, high performance tires.
- Gravel Grinder Open Tubular – We recently added a handmade version of the already popular Gravel Grinder which takes the successful mixed-condition tread of the Chicane, widens the center section to reduce high speed drag and adds a second layer of puncture protection for the ultimate confidence-inspiring ride over looser gravel conditions..
- Vulcano Tubular in tan – our most affordable tubular is now available in two sizes (23mm and 25mm) and in both black and tan casing.
We’ve also expanded the number of vulcanized offerings adding the 27mm Paris Roubaix road tire, the 33mm Strada Bianca gravel tire, the 33mm Chicane cross tire, and a 33mm version of the Gravel Grinder.
