Continental Grand Prix 4000 S II Road Clincher, Black, 700 x 23-Inch

Continental Grand Prix 4000 S II: The grand prix 4000 s II is the reference tire on the market and has already gone through many stages of evolution. We are giving the flagship a new face. The discreet bead strip makes it possible to perfectly color coordinate to the bike without forgoing Black Chili tread performance. We have also expanded the size range: an additional 28 mm version provides better grip under poor conditions, improved puncture protection and greater comfort. The proven cornerstones of the 4000 s II remain unchanged: Vectran breaker for unsurpassed puncture protection, Black Chili compound for low rolling resistance and sensational grip - handmade of course in Germany. The Grand Prix 4000 S II is the ideal combination of comfort, puncture protection, and low rolling resistance. It's the perfect all-rounder for all conceivable conditions with excellent puncture protection thanks to Vectran puncture protection and BlackChilli's high mileage rolling efficiency. Handmade in Germany. Superior grip and less rolling resistance. Features: This unique tread rubber mixture which is only produced in Continental's German factory has revolutionized bicycle tires. BlackChili Compound improves rolling resistance by 26 % and provides 30 % more grip than activated silica compounds. Premium tires with BlackChili Compound also impress with higher mileage and unlike many multi-compounds, provide a consistent ride from the first to the last mile.
