The Continental Grand Prix series of racing clinchers is the top choice of serious race bike specialists all over the world, and has been for many years. The latest incarnation is the Grand Prix 4000S which has the same construction as the GP4000 but with a new BlackChili special compound. stands for sport, special and “schwarz“ – the german term for black.

Continental Grand Prix 4000 S - black 23-622 mm

Continental Grand Prix 4000 S 

The all black Grand Prix 4000 S catches the eye with its big silver labels. It matches every high-end racebike perfectly and can do more than just look good. With the new Black Chili Compound rolling resistance is reduced by 26%, grip is increased by 30% and mileage is increased by 5%.

The new compound

How are these figures possible..? The carbon filler particles within the rubber compound are reduced to 1/10th of the size of standard carbon particles. This creates a closer knit with the particles having more points of contact with each other, thus forming a tighter bond, (increasing mileage performance) and also with the road (increasing grip). Also the way in which the particles interact with each other has a dramatic effect on reducing rolling resistance. Black Chili is used by several ProTour teams in 2007.

Vectran anti puncture protection

The all new Vectran breaker belt, developed and patented by Continental, surpasses even the famous puncture resistance of the former leader in this category, the GP3000. The extremely strong Vectran fabrics are more flexible and lighter than all other puncture protection materials. Vectran offers more resistance to cuts than Aramid, is five times as strong as steel and features less weight than a nylon double breaker. It also maintains strength in the wet.
