Challenge Strada SC HTU
Challenge Strada 22 HTU tires are good choice urban usage or any type of road cycling. Thanks to the 320TPI it has good grip and durabilty. Thread count plays a major role in the weight, suppleness and durability.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. Tubeless tires are made for better riding quality thanks to the loss of the inner tube's weight. On the other hand it has a lower chance to puncture than the tires with inner tubes. Challenge is using an extra layer called Puncture Protection Strip (PPS) in their products, to reduce the risk of punctures.
Handmade tubulars are non-vulcanized. 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.
