Description of Continental Grand Prix 4000 S II Folding Tire - 23-571

The Grand Prix 4000 S II is the reference tire in the road bike market and has gone through numerous stages of evolution. The discreet bead strip allows them to color coordinate the tire to match your bike perfectly without losing the BlackChili tread performance. The proven aspects of the 4000 S II remain unchanged. Vectran breaker for unsurpassed puncture protection, advanced BlackChili compound for low rolling resistance and sensational grip, and handmade in Germany of course.

BlackChili Compound
This unique tread rubber mixture which is only produced in Continental German factory has revolutionised bicycle tyres. The resultant compound showed a new relationship between grip and rolling resistance. This "Elevated level", as it was previously known, was given the name "BlackChili". The latest polymers, nanoscale soot particles and optimized fillers all guarantee a unique performance, from downhill MTB tyres to the time trial tyres of the ProTour, they are second to none in their respective areas. 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 fi rst to the last kilometre.

Vectran™ Breaker
Vectran™ is spun from Vectra liquid crystal polymer, which results in a thread that is thermoplastic and has multifilaments. This semicrystalline material is harder then aramid, has five times higher tensile strength than steel and in addition, is also lighter than comparable nylon thread. Vectran™ maintains these attributes even in the most adverse weather conditions.
