Continental GP4000 is the world's most popular road bike tyre. A proven performer on any road surface, Continental GP4000 achieves an unpassed standard of high performance and durability.

KEY BENEFITS:

• Low rolling resistance (fast in race conditions)
• Great mileage and puncture resistance (durable in traninig conditions)
• Increased traction through corners and in the wet (versatile in all conditions)

The Continental Grand Prix series of racing clinchers are the top choice of road riders all over the world. The latest incarnation is the Grand Prix 4000S, with it's patented Black Chili Compound that has : lowered rolling resistance by 26%, increased traction by 30% and improved mileage by 5%. 

The all black GP4000S catches the eye with it's silver detail, and looks great on any bike.

Taking bicycle tyre compound performance to the next level

Black Chili is the name for our latest tyre compound which hit the market in 2007 and has fast become a hit with cyclists across the world who have marvelled at its performance beneifits.

The fact is that Black Chili will improve our tyres performance in all areas. We can even make a tyre to last longer, yet also grip better and roll faster! The figures are astounding; 26% lower rolling resistance, 30% higher grip, and even 5% longer mileage. Black Chili is only made at our factory in Korbach, Germany. No other tyre facility in the world has access to its secrets.

Black Chlli is a new tread mixture, the result of the latest research from our polymer and raw material laboratories in Hanover, Germany. Continental AG refined newly developed synthetic rubbers with proven natural rubber with powerful profile blends. These are 'nano' sized soot particles, who's surface properties are optimised for use in bicycle tyres. These smaller particles enable the tyre tread to deform around surface objects more quickly, improving grip. They also form a tighter bond with each other thus improving compound strength for improved tread life and less chance for lugs to rip and tear on our MTB tyres. The way in which these particles interact with each other also lowers rolling resistance.

These new polymers and carbon fillers make Continental racing and mountain bike tyres the quickest and safest tyres in competition!

Compared to the previous leading Continental tyre compound, the Activated Silica (ASC) tyres, Black Chilli offers a 26% lower rolling resistance, a 30% increase in adhesion quality, and a 5% increase in tread life. For road racers and MTB trail riders, the speed and handling advantage is clearly noticeable!

The 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 and Continental teams.
