Continental Grand Prix 4000 S II Tire Black Folding Bead and Black Chili

A new relationship between grip and rolling resistance
This unique tread rubber mixture which is only produced in our German factory has revolutionised bicycle tyres.
BlackChili Compound improves rolling resistance by 26 % and provides 30 % more grip than activated silica compounds.
Premium tyres with BlackChili Compound also impress with higher mileage and unlike many multi-compounds, provide a constant ride from the first to the last kilometre.
