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.

Best tires made. Fast. grippy and dependable.
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.
Best Tyres I have ever used for all arround road riding
Great tires! I have used these tires for the past few years. Good grip, excellent puncture protection, long lasting rubber. Highly recommended!
these are fast, and as durable or more durable than any comparable tire intended for fast riding or racing. Excellent grip. I use these for racing crits and they have excellent grip when cornering, low incidence of flats, and improve ride quality (I always use latex tubes which may help some in that regard). They fit just a bit snug, but not bad. Much better than the opposite (go on so easy you wonder if they will stay put). I can recommend these to anyone who wants a fast tire with great ride and grip qualities, that is as flat resistant as you can hope for (good, but not gatorskins)
I’ve bought these and previous models and they are fantastic. Never had a puncture. My view is to always buy good tires and I don’t think you can get much better than these.
1 tire fast and grippy enough for racing while durable enough for training.
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.
This is a really great tire for all around cycling. Nice ride, quite supple, great handling. On the negative, which for me is unforgivable, is that the sidewalls are extremely prone to failure. This makes them dangerous, and untrustworthy. I have owned two sets of the previous GP4000 and never had a problem with either, and ran them between 3-4000 miles each. With these, the pair both catastrophically suffered from sidewall failure, both with less than 400 miles on them. In both cases, the roads were smooth, and free of grit, they just gave way, and burst. Have suffered through a bad crash, I could never buy these again.
Have used these tires for years. They provide excellent grip and feel great on the smooth and rougher roads. They inspire confidence when cornering and hold their grip nicely. I have found they get a little jumpy after 3000-4000km and lose their grip slightly by that point. No issues with flats although ride easy on large gravel...that is where I had my single flat over the past two years.
