Vulcanized clincher, cyclocross tyre. Light weight (330g) and durable with an extra layer of puncture protection(PPS). Vulcanized treads are stiffer, that makes it harder to worn-out.
Challenge Chicane RACE VCL tyre is an amazing vulcanized clincher cyclocross tyre. The tread was designed to grip on any surface that a pro cyclocross rider could meet, like wet mud, slippery mud, clay, soup, peanut butter—the list goes on. Vulcanized clinchers went trough the process of vulcanization, which has some negative effect on grip, and flexibility, but it has higher resistance to oxidation, wear and tear abrasion. It is generally accepted that in the 19th century Charles Goodyear discovered that by cooking natural rubber with sulfur he could create a long-lasting rubber that had an almost infinite variety of uses. This irreversible process of causing the rubber molecules to link together with a curing agent such as sulphur is called vulcanization. These tires can be folded and are far lighter than their metal beaded equivalents. The metal beaded tire, while far cheaper, gives a harsher ride. But even though the tubular technology remains the apex, a good, high-end clincher on a hand-built cross three spoke wheel gives a wonderful ride. The tread vulcanized onto clinchers is generally thicker. For this reason, a clincher tire will usually last longer.
