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.

Felt the difference after changing from 25mm - less resistance on climbs and have been smashing PRs in climbs by 1-2+ mins!!! Highly recommended
Not much more to say really; great tyres, great longevity, great grip and a great price.
Always happy with continental grand prix 4000s tyres
A grippy long lasting tyre that can be relied upon
These are the third set of Continental tyres that I've purchased during recent years and I am very happy with their performance so far - as I have also been satisfied with the 'older' models of this tyres. I have completed many thousands of kilometres on each of the sets of tyres with no problems. I have been lucky enough to only experience two punctures in all this time neither of which can be attributed to the tyres themselves. I'm sure that the tyres have given a higher level of puncture resistance than the cheaper brands that I used to purchase and, incidentally, Continental do specify some elevated puncture resistance in the information supplied with the tyres. They are hand-made in Germany and that also gives me some reassurance that the tyre is well made and will stand up to the rigours of long distance and trouble-free riding. I'm only a 'weekend warrior' and retired but I'm happy to continue to purchase these tyres and would recommend them to others.
These tyres are grippy and supple but still have good rolling resistance Resist pincturing as well, I supose thts why they are one of the most popular tyres.
Been using these for years and they continue to deliver. Handle to training kms and racing kms equally as well.
These are good reliable tyres. I have purchased them for many years now and have used them for racing as well as training. I get good mileage and will continue to used these tyres.
