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.

Received several weeks ago. Rode on them a week ago. Pleased so far
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)
1 tire fast and grippy enough for racing while durable enough for training.
Been riding these for about 10 years now, after growing tired of flats on lesser tires. Rarely do I flat these days (riding/racing 3-4 days/week) and just saying that is a risk I can afford to take. No jinx can change my experience. Not looking to switch since these are respected as the best all-around tires on the road.
For either racing or just Strava hunting these tires are fast and durable.
My wife and I ride tarmac, remote back roads, and dirt roads. Our rides are generally long and self-supported. We choose the 4000s for durability and resistance to puncture. These tires are fantastic for the kind of roads and long mileage routes we ride. We get very few punctures with our tires, even though we have rocks sticking into them and bouncing off of them on most of rides. We highly recommend these tires.
I have these tires 4 stars based off friends from my group ride. These guys have been riding for over thirty years. They know what works. I have only mounted them, with no rides. To the touch the rubber feels grippy. I have no doubt that these will be the best tires that I will ever ride.
About two years ago I switched from Vittoria Diamante Pro tires to these Continental Grand Prix 4000 S-II after looking for tires that are more resistant to punctures by rocks and glass. After reading many reviews, I settled on these Grand Prixs. I have been very satisfied with the puncture resistance when compared to my old Vittorias. I've gone through the occasional broken glass and many rocks without incident. The GP's seem to last about 1500 to 2000 miles in my mixture of city and country road riding. Their traction is good. I haven't had a problem on the few wet roads on which I've ridden. But, I am a fair-weather rider. I would have rated them a 5, but I had two tires that had some thread-like material unravel from the area around the rim. There didn't appear to be any effect on the tire performance or longevity, but it was a bit worrisome because I hadn't previously seen this on any tire.
I,ve been using these tyres for a few years now and I am very happy with the quality and the price for the 2 pack was fantastic
