This is the Challenge Criterium Seta Extra Tubular Road Tyre. Forever the choice of professional riders. Numerous victories and podiums have proven Challenge Criterium Tubular Seta Extra the top Pro racing tubular. This tyre features a silk carcass, which is stronger, lighter and more supple than all other carcasses. All tubular and open tubular produced by Challenge are special hand-made products. Machines are not able to produce them and the manual skill required in each step to obtain a good quality standard is very high. The casings have a high TPI count that can reach over 300 tpi. Their production avoids any vulcanisation processes to enable all materials to keep their suppleness and flexibility. The tread is slowly hand glued on the casing which is previously mounted and inflated on a rim. By using this method the tread is relaxed on the casing and does not suffer any tension when inflated. The result of this is a lower rolling resistance, increase in comfort, more precise handling of the bike and better grip.
Hand made tubulars are well known by professionals and is this type of tire that is preferred for the long stage races. To give the best possible grip in curves Challenge uses the most updated materials to obtain flexibility, suppleness and this results in absorption of irregular surfaces giving to the cyclist the best possible contact patch. The wheel avoids jumping and the tire will deform and absorb the irregularities acting in some way as a shock absorber. A special fabric is placed between the tread and casing to increase puncture resistance “PPS” (Puncture Protection System) technology. Comfort means reduction of harmful vibrations for the wrists and neck, these vibrations, will end causing inflammatory problems, as a hard tire will transfer all the vibrations directly to the racer body. If you have never tried a “hand made” product, go to a local shop and ask to see one. Touch the product and look at its construction and the side walls. You will immediately notice the difference.
