The new GP4000 S II really does deliver on all fronts, combining speed and amazing handling with impressive puncture resistance and extended tread life. Just like the original GP 4000 S, this is one of the fastest, most durable, and best-riding tires available. In fact, it's even better—Conti claims that thanks to continued R & D, they're able to improve the venerable Black Chili compound by 3-4% every year, so the new model has even better adhesion in wet and dry conditions, better durability, and lower rolling resistance.

For those not clued into Black Chili, this is the lingo Conti uses for their top rubber. As the name implies, it can only be made in black—hence this tire's all-black center tread. In a nutshell, Black Chili is an incredibly dense rubber, made up of particles roughly ten times smaller than those typically used in bike tires. Placing this wonder compound directly at the contact patch results in a tire that's not only more durable, but more able to conform to (grip) the road. It's also more resistant to UV rays, helping it to resist cracking and premature tire wear. Add colorful sidewall options to the mix and you've got the best of both worlds, performance and style.

The tire also features Conti's patented Vectran puncture protection barrier underneath the tread. Originally developed by NASA in the construction of space shuttles and suits, Vectran is a tough but lightweight material that allows Conti to keep their tires extremely light while providing tremendous puncture protection.

The Grand Prix 4000 S II features a three-ply 330 TPI casing. Kevlar folding bead. Max inflation is 120 PSI. Claimed weight is 205 grams (700c x 23mm)

Better than ham & eggs

Years ago I rode on Champion Del Mondo sew ups, I have always said that this was my number one tire, then I bought some challenge Paris roubaix from bike tires direct these come up to match the Champion, but I found them a little frail. Then I tried the Continental 4000 s and I love them. I am 68 and have ridden about 400k miles and have tried everything within reason and I will highly recommend these to anyone!

About the best race tire on the market that is rugged enough to train on.

I use these for riding, racing all of it. I've never found a tire that performs this well and also holds up to regular riding on imperfect roads.

There are many tires that perform this well, but none are as flat resistant and durable as the GP4000SII

Rock solid tire, durable, flat resistant, and rolls well.

Have trusted this tire for commuting and training rides for several years. Flat resistant in urban environments and on thorny desert roads in Southern Utah. Low rolling resistance for such a durable tire.

Impressive to this guy

I picked these up for my triathlon bike, which was in pretty desperate need of new tires. The brain trust at Slowtwitch raves about these tires, and I don't know jack about equipment, so I followed the crowd. To my novice eye (been cycling about 2 years), these are a big step up from what I had previously. The handling is really smooth. I live in the country (sort of), and roads are rough. These tires have held up nicely. I'm really happy with the purchase.

Again, relying on Slowtwitch, I got the impression the price could have been a bit better. I did get them on sale at BTD, and they were still a very good price. I would definitely buy these tires again, and from BTD.

Nice ride and good grip.

I've been riding these for a couple of months now and I'm very happy with them. I'd been riding 23s from Vredestein for many years, so these are my first Conti tires and my first time buying 25s. Our roads in PA can be a little rough so I am enjoying the little bit higher volume tire and the overall ride quality. The reflective strip is a nice touch that really does catch the eye but I miss having some color on my tires. That is probably the only regret I have about these so far. If you want a high-quality, high-performance tire that delivers a nice ride as well as good durability, I don't think you can go wrong with this one.

superb all around tire for all conditions

a very well handling, light, responsive tire. I am using the 25C version and they actually measure out to 27 mm when inflated to 98 psi which is what I run the rear at, the front I run at 92. I weigh an even two bills and have found these tires to be ideal for all seasons as they also provide excellent puncture resistance with the high strength belt Conti uses. Durability is also good, you do want the tire to show wear over time as this indicates the suppleness of the tread. Check 'em out.

GP4000S II inflates to wider than sidewall spec

GP 4000S II inflates to wider than sidewall spec. After blog search, purchased GP4000S II to ride in Tour of Flanders Sportive. Blog recommendations were to use wider tires inflated to lower pressure to take out some of the harshness of riding on the Flemish cobbles. Measured width of forks, chain stays, and seat stays (eight year old Fondriest carbon frame and Easton fork) and determined not wide enough for 28mm but 25mm should fit. Purchased and mounted 700x25 GP4000S IIs and inflated to 95 psi. Measured width of inflated tires (digital micrometer) was 27.75mm leaving about 1 mm clearance each side between tires and fork and stays. Tires rode well on the cobbles - comfortable, good traction in the damp, and most importantly NO PUNCTURES. Remounted 700x23 other brand tires that had been removed to mount the GP4000s IIs to regain tire-to-forkstays clearance and will use the GP4000s IIs on another bike with greater forkstay widths. Great tires, next time this bike needs tires will probably buy another set of GP4000s IIs in 23mm width.

Awesome tires

I am very happy with these tires' durability, combined with performance. They corner extremely well, even at race speeds, and even in the rain. Being 23mm wide, the size I bought provide a minimum of rolling resistance, and they're fairly light as well, while still having the Vectran breaker belt and other layers of protection against glass, etc. I have even had these tires on singletrack for a short distance (a runwalk was taking up the bike path at that point) with no issue.

PLUSH!

A switch from 25C from 23C tires has been one of the best changes i have made on my bike since new wheels. Running so much less air in the 25s, they seem to just suck up the standard road rattle.

Continental tires come highly recommended to me by a of friends as a durable, long wearing tire. I haven't really found them to be that flat resistant and in fact i cut one tire beyond use with less than 300 miles on it. I HIGHLY recommend that you buy these tires on line and not at your LBS. I paid $66 bucks for a pair of these at Bike Tires Direct and when I replaced my cut tire at LBS i paid like 78 bucks for one! OUCH!

My 'go to' tire!

I love this tire for a number of reasons. First, it's one of the few I can find that come in the 700 x 20 size. While I have read and understand the logic behind the physics of a bigger tire, I'm a firm believe in the 20s and will continue to use them until I cannot purchase them any more. These Continentals are consistently reliable and I am always confident when riding on them. I race with these as well as do high mileage distance rides and really get a ton out of these tires. I rarely have blowouts which gives me an even greater confidence to ride hard when racing. I've found 20s in other tires that haven't lasted nearly as long as the Continentals. It's a solid, consistently well performing tire that I will continue to purchase.

Continental Grand Prix 4000S 700C

Have used for years. Continentals are dependable, love the wear indicator dimples & roll & corner efficiently.

Do wish access to longer stem presta 60mm tubes was easier. Why don't more manufacturers make such? With the increase in carbon wheels, longer stems is necessary. And I prefer non-threaded smooth stems so the grommet in my air pumps are not worn out by the thread abrasion faster. Please consider this.

Hands down the best tires I've used thus far.

Rides very fast, stable and much more comfortable than other even other continental tires. On my 16mm inner width Ultegra and Carbon rims it measures at roughly 26.4mm at 80 PSI.

Hills, wet and dry

Order it to ride a fondo in Panama, the 2017 Ocean 2 Ocean, lots of hills and it was a hot day.

The extra 3mm of the 28mm installed on the rear, helped me put power more efficiently to the road and I was not as tired as I had ridden the route a few weeks before with 2525 and finished in more time, more calories consumed and much more power lost

Fast delivery and good customer service.

Had a question about my order and was able to get a hold of a representative right away. They helped me with my question by going above and beyond what I expected. Delivery was fast, the items got to me before my race. I recommend this seller.

As for the tires, well tires are tires to me. I put them on my bike and I race as fast as I can go. I got these onecs based off of others reviews online. They said they were good for races without compromises of super thin tread to cause a flat, and great rolling resistance when paired with latex tubes.

I normally get 2,000 miles out of these tires. Rolling resistance is great. An important feature is installing tires compliant with tire errors. Unfortunately, finding those arrows can be quite difficult.

Best all around tire hands down. There is a reason why Conti keeps making this tire!!! Not the fastest but best All around for riding and racing. Super sticky

Got this tire in a 20mm to fit an old back up TT disc. So glad that conti still makes this option as 20mm tires are fading out in the TT world because of RR(rolling resistance) tests. Raced all year long and and a few training rides still super sticky and fresh. Fastest all around tire in my opinion.
