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.

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
Tried lots of tyres over the years, but for their combination of puncture resistance, grip, low rolling resistance and longevity there's nothing better than these. Not the cheapest, but the best folding clincher or high milage riding. Price from Probikekit was great, with a bonus discount. Free, fast delivery was the usual great service too.
the resistance of tire is almost zero! Also grip was good
Delivery was good! Comfortable to ride with this tires!
Brilliant, anyone want to buy some 23s
The best tyre I've ever used: light, grippy in all conditions, incredible puncture resistance, and last for over 5000 miles! Used them for several years and can't see myself ever wanting to try something different.
Fat road tyre but really smooth rolling. Quiet but grippy rubber.
Fastest clincher rubber that I have ridden. Ride well, reasonable longevity.
Love these tires! A rock-solid training tire, and very well priced! Highly recommended!
Have used these for two years now on all my bikes in all weathers, I like the 25mm width option for more comfort. Grip is good in wet and dry, get over 4000 miles out of each set of tyres. Only get the odd puncture no more that other tyres I have used in the past. I do over 7000 miles a year on my bike so appreciate good tyres.
Without doubt the best tyre I've run to date. Fast, smooth and very very grippy.
Always been a big Conti fan, particularly with their excellent Gatorskins, which have never let me down. Bought a pair of GP4000S IIs 700x25s to replace the excellent Mavics that came with my Ksyrium Elite S wheels. On first 30 mile ride to bed them in I got a front tyre blow out descending a steep hill (part of the Prudential London Ride Classic rout that the pros rode a week later). The tyre wall had a split in it and PBK eventually replaced it after 10 days of toing and froing by email including photographic evidence. I suspect it was a manufacturing defect - maybe a bad batch. The rear tyre survived the Prudential Ride 100. The extra width of the 25mm make for a really comfortable ride with excellent handling and good rolling. I have downgraded to 3 stars because of the defect, but would have given 5 stars based on the rear which has been fine.
best clincher tyre i have ever used. combined with PBK's rapid dispatch, I've experienced an unbeatable combination.
Nobody who is buying this tyre can underestimate the awesomeness of it. Superb grip level, good puncture protection and low friction. What more could you want from a race tyre? However PBK let the side down in that it was more than a month late :-/
Excellent grip and comfort, 25mm is fast rolling. 1000kms in and no punctures, quality product.
With a week of riding behind me these tyres feel so much grippier than the stock rubber supplied by Giant. Acceleration feels quicker and they are quieter than my previous tyres. I feel more confident with these.
these tyres seem to be as good as people say they are really smooth and very quiet
