Continental Grand Prix 5000s 700x25c Black / Transparent Tire A new era has arrived, The best all-round tire in its field takes performance to a new level. Run faster, in more comfort and with better puncture protection. Built to give the best! After 14 years and numerous special editions, the popular GP 4000 has been updated and the GP 5000 is born. The GP 4000 S II is recognized by all as the best in its class, an excellent performance and super reliable cover. Now, 14 years after the presentation of the first GP 4000, the legendary Continental has been completely overhauled and has been better in every single area. Continental claims 12% less rolling resistance for the 5000, 20% more puncture protection and 10% less weight and offers a smoother, more comfortable ride. Continental's patented Black Chili compound has been updated with a new formula and laser-engraved tread pattern to offer further improved cornering grip. Continental also claims a more aerodynamic clincher surface with less turbulence. Active Comfort Technologies A revolutionary approach to cycling. Active Comfort technology is integrated into the rubber and absorbs the vibrations and irregularities of the road you are pedaling on. Lazer Grip makes you one with the road. The profile with micro laser structure expands over the shoulder of the tire and offers unparalleled cornering ability. A one-of-a-kind Continental compound, produced only in Germany, which revolutionizes bicycle tires! The compromise between greater grip and rolling resistance has been taken to the highest levels with the BlackChili Compound. Numerous first places in tests confirm the measurable and recordable benefits in the laboratory and in the field. The new generation polymers, the carbonaceous particulate resulting from nanotechnologies and charging agents, guarantee a truly unique performance. From downhill MTB tires to time trial bike tires, the ultimate in use! BlackChili Compound improves rolling resistance by 26% and at the same time offers a superior grip of approx. 30% compared to active silica compounds. Tires made with the BlackChili Compound also offer superior mileage and, unlike multiple compounds, consistent performance from the first to the last kilometer. Vectran Breaker Vectran is a liquid polymer yarn that transforms into a thermoplastic and multifilament compound. This semi-crystalline material is harder than aramid, has five times the tensile strength of steel, and is also lighter than an equivalent nylon line. Vectran maintains its characteristics even in the most difficult weather conditions.
