Challenge Gravel Grinder TLR Clincher Tyre
What's the point in training till you drop if you're going to be losing efficiency and speed in your tires? Ride quality is paramount, and no other tire offers the supple, responsive traction of a Challenge Open Tubular, eliminating barriers in achieving your maximum speed and potential. Open Tubulars mount like a standard clincher, but are made using the same artisan handmade process as tubulars and maintain most of the suppleness and ride quality gained from a handmade tubular.
Supple tires not only offer a sublime ride, they reduce rolling resistance, and enable more precise handling and a greater range of pressures. They adapt quickly as the tire changes shape while cornering and rolling, which increases road surface contact and grip while cornering, plus shock absorption as you pass over irregularities in the road.
Non-vulcanized: Ultimately the major difference between a Handmade Tubular or Open Tubular and the majority of clinchers is that it will avoid the heat and pressure process called vulcanization, which most tires undergo in production. It is used to bind the materials, but compromises the ride quality when the rubber gets stiffer. Treads are hand-glued onto Challenge Tubulars and Open Tubulars, and the latex and rubber maintain their ideal quality.
Thread count (TPI): Thread count plays a major role in the weight, suppleness and durability of Tubulars and Open Tubulars. The higher the number of threads per inch (TPI), the thinner each individual thread, making a thinner and lighter casing and a more supple tire. Our lower TPI casings are thicker and more durable.
Casings: Corespun cotton casing is lite and supple, and available up to 320TPI for maximum control and performance. SuperPoly polyester casings are less expensive and more durable, still providing the qualities of top-end tubulars.
Puncture Protection Strip (PPS): An extra layer of uniquely-crafted fabric with highly resistant properties sits between the casing and the tire to reduce the risk of punctures. Tires intended for use in intense conditions with a high puncture risk are reinforced with a second PPS layer beneath the casing.
