Description

Faster through the corners.

The popularity of the first-generation Continental Grand Prix 4000 was thanks to its unmatched versatility: It was light enough for a hilly ride, but beefy enough to survive chip & seal unscathed; its low rolling resistance made it an ideal choice for race wheels, but it didn't puncture at the first sign of road debris; it stuck to the road when you cornered at high speeds, but it didn't feel sluggish when you accelerated. It was a design that needed little in the way of improvement, but the engineers at Continental made some substantial improvements nonetheless -- and the finished product is known as the Grand Prix 4000s Clincher Tire.

The GP 4000s offers Continental's Black Chili rubber compound. They first developed this for the Moto GP racing circuit, and they've brought it over to their top-end bike tires. Super-tiny carbon black particles are incorporated into the rubber formula to provide benefits along three lines:

1. The tiny size of the Black Chili particles allows them to mold to the road surface more readily. It gives the tire greater ability to conform to imperfections in the road surface. Better contact with the road means better grip in demanding situations such as high speed cornering.

2. Since the Black Chili particles are so small, more particles fit into the contact patch of the tire -- reducing tire wear and increasing tire longevity.

3. The Black Chili particles are literally more flexible, which reduces the rolling resistance of the GP 4000s.

The Continental Grand Prix 4000s has a dynamic siped tread pattern for all weather traction. A Vectran layer sandwiched underneath the tread adds significant puncture resistance. The GP 4000s is available in 700x23 and 700x25 in Black/black.

Awesome tires

  • Familiarity: I've put it through the wringer

Definitely my go-to for tires on my argon, they have great grip and amazing durability. I've hit those unavoidable things on the road and thought "I'm definitely going to go flat", only to find that the wheels kept rolling with no issue.

Worst tires ever

  • Familiarity: I've used it once or twice and have initial impressions

in less than three months, both tires tore the sides unable to be repaired. It seems that the material came defective since both had the same problem, unfortunately there is no guarantee. Will never buy contis again or in backcountry for selling old tires.

I only used no more than 10 times at 110 psi on good condition roads.

BEST TIRES EVER!

My absolute favorite set of tires! These have lasted me a long time, and they're incredibly grippy!!!

I like them already

  • Familiarity: I've used it several times

Recent convert to both Conti's and 700 x 25, at the recommendation of Mike Nelson at CC. My bike came with Griplink/Powerlink tires which look skinnier than the reported 23 mm. Read many articles on the advantages of increasing tire size, so I did. A good friend is a long time Conti fan, so I jumped on these when they went on sale. Great tires so far. Yes, they look a bit big, but compared to my previous tires, I expected that. I like the nice round profile look. We were headed to New York for the GFNY and I wanted a durable tire that would be comfortable, and inspire confidence descending. It excelled at everything. There were dozens of flats, but not me! Rough roads didn't feel as bad, and I was less worried about downhill switchbacks (crashed on a tight turn a while back, a bit gun shy these days). I've ridden Vredesteins, Hutchisons, Vittorias, and Yksions. I relly am impressed with these. I'm a convert. No excessive wear so far after 500 miles. I'll post more after I wear them out!

Great Tire

  • Familiarity: I've used it once or twice and have initial impressions

I've been a dedicated GP4000S 23mm rider for a while now. The 25mm tire lived up to exactly what I expected on my ride with rough road and rough dirt section.

Posted on

I ordered these 700 x 25m and mounted them on a set of mavic cross rides. They seem larger than the other Conti Ultra Sports I replaced which were also 700x 25 m. I now have only a few thousands of clearance to the seat stays on my frame. These tires just look larger all the way around. The CUS actually measure 25 mm were as the Gran prix 4000 S measures closer to 27-27.5 mm. Really they look and seem closer to a 700 x 28 which I would not have purchased. Is this normal and do they run larger ? Now I'm considering the 23m in that tire. Does it run large to,, closer to a 25m ? I'm getting confused.

Thanks,

Tire sizing can not only vary by manufacturers, but also by models within a particular company. It is normal for some to vary as higher end tires are handmade and will have some variations. As for the tires you received, you can return them to us within 90 days for a store credit and get some different if you prefer. If you have any additional questions or would like help setting up a return, please feel free to contact our customer service department at 888-276-7130.

Worth the money

  • Familiarity: I've used it several times

Last year was my first season of cycling. Shelling-out $75 per tire for my 4000 S tires hurt, but after having to fix a flat Vittoria during a lightning storm - it was time to get good tires. But I wondered, "How can there be that much difference in a tire to warrant that kind of price?" I found out. The Contis made a HUGE difference! Having previously run Vittorias, the Conti 4000 S is much faster, and gives me confidence during cornering and downhills. I chose to ride the 4000S last fall in a charity tour through New England. Good choice and well worth the money. All kinds of junk along the road and zero flats. And they made quick work of the big bad mountains of Ludlow. They are VERY difficult to mount on my Rolf Prima Echelons wheels - have to use a tire tool the last 6 inches or so. VERY pleased with these tires - 750 miles and they're still like new. And now that CompetitiveCyclist has them for $35 - bought another set - wish I had the funds to get a third set, but I suffer from the disease, roadbikeitis - it takes over your soul, then works it's way into your wallet - financially debilitating.

Responded on

Amen to Roadbikeitis. I'm very ill.

Awesome Chili

Just purchased three of the 25m. Mounted them to my 60mm carbon wheel set without any problems. They look great and I couldn't help but notice the grip is so much better than my stock Specialized Turbo Pro's. These have a small directional arrow on the sidewall, so watch for that when you install yours. I think I'm going to really like this tire.
Thanks Competitive Cycle for the Super 50% off deal on these.
Update: After riding my usual lunch ride, with my new Conti's I had 7 personal best ride segments on Strava. On the same ride course, and I wasn't even pushing it, just having a good time! These tires are the BOMB! . . .Luv em!

How small are the Black Chili...

How small are the Black Chili particles, exactly?

Best Answer Responded on

The Black Chili particle is 0.00000001m versus a normal particle, which is 0.0000001m. One zero may not seem like much, but to put it in perspective, if you were to place one Black Chili particle next to a soccer ball, the ratio would be the same as that soccer ball compared to the earth. The attached picture demonstrates the advantage of such small particles. You'll notice how well they conform to contours in the road on a microscopic level, which creates a grippy, secure and fast riding tire.

10:1 in one dimension is 1000:1 in volume. The earth is not 1000 soccer balls. Since a soccer ball is approximately 9 inches in diameter, you can make the comparison to a sphere that is 90 inches in diameter, or about the size of a small bedroom.

Responded on

Actually, they are not making a 10:1 comparison. They are comparing the size of a Black Chili particle (0.00000001 m ?diameter?) to the size of a soccer ball (0.22 m diameter), and then making an "equivalent" comparison of that soccer ball to the size of the Earth (which is actually ~12,700,000m diameter). So if you do the math, it is still slightly overstated. The comparable size would actually be a sphere that is 4,800,000m in diameter which is larger than the moon (3,400,000m), but not as large as the earth. Nonetheless, these are REALLY small particles.

And they ride, grip and roll great, by the way.

Responded on

What is a "normal particle"? A normal particle of what? What is a "particle"? I doubt it's an atom; it must be a molecule -- but a molecule of what substance?

Two Thumbs Up

These tires rock...grippy...flat resistant and you get some serious mileage out of them. The Customer Service from Competitive Cyclist is top notch...got my order fast and all was just perfect. 2 Thumbs Up!!!

As of right now my favorite tire.

  • Familiarity: I've put it through the wringer

Actually it was recomended to me from a frien who owns a Bike sshop here in Sarasota, and since i put the first set of 4000 S's i really enjoyed the way they feel in the dry and in the wet, i just bought another set because the were offerd for half price, so i figured now is a good time so i have a new set when i need them, i have them on both of my sets of weels, and thet really work for me, Contis 4000 S thumbs up fro me.

Competitive Cyclist the Pro Shop

  • Familiarity: I've used it several times

I just wanted to comment on the expertise and professional response I received from Competitive Cyclist website on sending my order out on time and in good order. I received my order in three days with no shipping cost (order was over $50.00). The tires, it goes without saying, are some of the best clinchers in the world, but beyond that, they were only 37 bucks apiece :). What a deal for this product; and Competitive came through sending them out promptly. Can't say enough about it. If I need bike I know where to go. :)

My favorite tire for training / racing.

  • Familiarity: I've put it through the wringer

I've tried more than few different tires on my road bike - Kenda, Michelin Pro3/4, Hutchison, Vittoria - and this is by far my favorite tire. I got a bit over 5000 miles out of my first set by rotating the front and rear a few times.

In terms of pure grip - I prefer the Michelin tires. They stick to the road like glue, but seems to go flat every few weeks. I weight about 175 lbs for reference. The Contis have about 85% the grip of the Michelins, but still handle very well. Wet weather grip is pretty good, much better than some of the Kenda tires I have tried.

Puncture resistance is the strong suite of these tires. I typically only get punctures during an early season rain when debris gets washed to the road. If you want even more puncture resistance, check out the Gatorskin. A bit less grip and more weight, but you will almost never get a flat.

Responded on

I never rotate my tires. I always want the best tire on the front. A flatten out tire on the front reduces the handling and if the front wheel slips you are going down, if the rear wheel slips you can correct it and stay up. I always put the new tire on the front and move the front to the rear.

Responded on

Agreed! The Michelins have way more grip (Pro 4 Endurance) and especially in the rain. Knock on wood, but I have not had any flats with my Pro 4?s with over 4000 miles on them. I just didn?t like the grip level of the Conti so I now use it on my Computrainer. It has been holding strong for the last 2 months with workouts everyday on the CT.

Used and loved them for years, not today

  • Familiarity: I've put it through the wringer

I used the Conti GP4000s for years. I probably had three to four sets on a couple different sets of wheels. I loved the ride and the handling and have no complaints about the performance of the tire. They did seem to wear out rather quickly and I had one developed a bulge and another two started unraveling at the bead. I also had a flat once a month or so during the hard training months. I thought this was normal. I found myself with a set of Vitoria EVOs and later Mavic Grip Link/Powerlink combo. I found both these tires had a noticeably nicer ride and were just as fast. All three brands wear out just as fast but the what I cannot explain is that I don't have flats any longer. I am still using the same tubes I stocked up on when I rode the GP4000s and the same pressure on the same wheels. All I can blame is the tire.

I'm looking for the new version of the continental 4000s size 700X25, is this the tire i'm looking for and please let me know what the differences are between the the new and the older version. Upon your response I will place an order.
my email address is jlboyarsky@gmail.com

Responded on

This is not the new version, that is the GP4000S II, if you really need a 25c then you'll have to look around for it.
Per Slowtwitch.com: "More specifically, Conti tells us that the price, tread pattern, advanced Black Chili compound, Vectran puncture layer, and 3/330tpi casing have not changed...What has changed, then? First, we get a rainbow of pretty colors in the GP 4000S 2... What else is new? Two big things: 1. A new 650x23mm size (ISO 23-571), 2. A new 700x28mm size (ISO 28-622)"

Responded on

The new version is the GP 4000s II. I've seen a few of these starting to hit the market, not sure if Competitive has them in stock yet.

Responded on

They are in stock :)

Posted on

I'm thinking about using the 4000s wider 25mm in the front and 23mm in the rear. Will this combo work on my road bike?

Responded on

Continental offers something similar to what you are thinking of with the Force/Attack combo.

http://www.competitivecyclist.com/continental-grand-prix-attack-force-tire-combo?ti=U2VhcmNoIFJlc3VsdHM6YXR0YWNrOjE6MTE6YXR0YWNr

But instead of running the wide tire in the front and the narrrow tire in the rear, they specify the 22mm Attack for the front for low rolling resistance and better aerodynamics, and the wider 24 mm tire in back for comfort and flat resistance. If you're going to mix widths on a road bike, i suggest following their lead.

Responded on

Sure, but why not ride 25 all around? You'll love it.

GP 4s is a great training tire.

  • Familiarity: I've put it through the wringer

Not the lowest rolling resistance out there, but probably the best for low rolling resistance coupled with superb puncture protection. Which makes these an outstanding training tire. Routinely hit 3000 + miles before the tread wears out. Which is easy to determine with the tread wear indicators, or by the old fashioned method of popping 2-3 tubes in a couple of days. Used to commute with Gator Skins, but got sick of the sluggish feel of those tires. Switched to GP 4s and find the puncture protection to be almost as good as the Gator Skins, but with a much lower rolling resistance.

Good Road Rubber

These tire are great for the price. They get the job done in a simple way. Grip well when needed in the corners. Durability is good. i'm a fan and would recommend these as one of the many good offerings from Continental.
