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.

Excellent product, highly recommanded .....Also excellent service from ProBikeKit, will buy again for sure.
Great tire at a great price. Received within a week of ordering with standard delivery
These are durable and roll great. I wouldn't, run anything else. Can usually get 4000 km on them.
Just got installed them a week ago. So I cannot fully review them. But so far, excellent grip in both dry and wet condition. Very quiet.
Vert good tire. Long l'as tong Andre vert good handling
An all around fantastic tire! Great durability, handling and rolling resistance. Worth the $$ and will last you a long time. Great for training and racing!
This tire/tyre is awesome! Very light and nice smooth ride! Delivery to Ontario, Canada was within the expected (2 weeks).
Best all around tyre for weight, grip, durability, puncture resistance
Items purchased received as ordered. Probikekit has consistently provided me with great service.
Great tires! Long lasting, very few punctures and they stick good!
I have used these these tires for years and seem to wear like a trooper. Tried other continentals (ultra sport) and founds these to last better... and much easier to get on the rims.
Delivery to Ontario, Canada was 5 days faster than info indicated when ordered. So FAST!!! And best price! No issues, can't wait for the weather to clear to get outside. Probike.ca you rock!
Great tyres that can last for more than 1000 km. Sweet ryding and they make you feel faster on your bike.
I've been riding on these tires for a couple of seasons, and they are very reliable. Rotating them every 10000 kms and the wear dimples are still visible after 5000 kms. With the Probikekit 15 % reduction on the purchase of 4 tires, it's a great deal.
I've used these tires for years, and find them long lived, puncture resistant, comfortable to ride, and consistently high quality. I would recommend them to any serious road rider.
these are my go-to tires and are excellent. While flat resistant, they are still easily punctured/cut off the center of the tire. These came with tubes as an extra, however the tubes seemed to me to be very old stock. I will not use them on a bike where I am riding long distances( if at all). Fast delivery and competitive pricing.
I rode the full season with lots of races. Only one well deserved flat this year which is remarkable considering I would usually get 6 or more with past tires. Also the tires have worn well and I would usually be onto a second set by the end of the season, but they are still going. Great performing and very predictable tires.
Great tires, best one for on the road. Rolling resistance low. Puncture resistance high.
Great tire on the road plus fabulous service from UK to Canada probikekit you are the best
I haven't installed the tires yet. However, I would like to comment on excellent delivery, did not to wait long considering it is being shipped from UK to Canada. Plus, it the correct items :)
Awesome tires, can't be beat for the money.
These tires live up to the hype and praise they have been getting. Wear well, corner great in wet or dry conditions and Probikekit has the best price and service in the world. This Canadian customer is 100% satisfied. Thanks Probikekit.
Great tires, no issues with these at all. Used them in a half ironman race in the sun and with a bit of rain on some slick roads. No issues with turning and no flats yet! Only had them for a month but still satisfied with my purchase!
