The Grand Prix 4000S II boasts global appeal as the best all round race bike tyre on the market. Not only is it fast and super grippy, thanks to its state of the art BlackChili rubber compound, but it is also tough with a healthy tread layer and of course Continental's Vectran anti puncture breaker layer underneath. So for reliability, longevity and all out performance for your race machine, the GP 4000S II is the only choice.
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 as shown opposite.
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.

Been looking at these tyres for a while, but needed a new set to get me through the autumn. I am very impressed, as they were easy to fit, and feel significantly better than my previous tyres - more grip, and smooth rolling.
Always great. Unfortunately, I had a side wall cut puncture on first ride with this set and had to replace one immediately. Not the tyres fault though and these things happen. As a user with 1000's of miles of hassle free riding on these over the years, I can testify for their underlying quality.
Been using these tires for over 2000km Provides good grip even in wet rainy conditions and pretty darn durable. Highly recommended for daily/training usages
Have used these tyres for over 8 yrs now and hardly every get any punctures with them and they run really well, would recommend.
Great service and prompt delivery quality products!
Best tyres what i ever had. Forget the Thorns and drilled tires. superior traction great overall
I have done 6000 + miles this year on 3 different types of tyres.The Grand Prix 4000S is without any doubt the best I have had by a long way.
great tyre , this the the second pair ive bought to go on my spare set of zipp wheels, great value recommended at 25mm
These tyres were delivered quickly on the standard delivery service, many thanks. Tyres now been on a couple of weeks and already noticing the difference these are making. Excellent so far........!
looked long and hard at these against my Schwalbe Durano's - opted for the GP4000's initially nice change & slightly better ride but really disappointed with puncture resistance 3 punctures in 5 rides - not a happy bunny :( may stick to durano's next time - thinking of buying a new set of wheels anyway & think durano's will be going on them
