The Continental Grand Prix 4000S II clincher is similar to the GP 4000, but the "S" stands for sport, special and "schwarz," the German word for black to describe the all black sidewall (with silver lettering). The GP 4000 S II is fast and sticky, thanks to its state of the art Black Chili rubber compound.
The Grand Prix 4000s II uses Vectran, a liquid crystal polymer that is light, flexible and strong. NASA has used it in the construction of both space shuttles and suits. Continental has patented its use in bike tires, which allows their tires to remain extremely light, while offering tremendous puncture protection.
Like its predecessor the GP 4000s, the II is one of the few tires on the market that features both low rolling resistance data and high puncture protection.
