Description

Like the outgoing GP4000 S, Continental's Grand Prix 4000 S II Clincher Tire continues to use Black Chili, but now has Vectran technology to boost puncture protection. Vectran is a multi-fibered thermoplastic yarn that is made from a liquid crystal polymer.

Claimed to be stronger than steel, this offers additional resistance to penetration from road debris while being ultralight. Combined with Continental's Black Chili rubber compound, super-tiny carbon black particles incorporated into the rubber formula, the GP4000 S II is versatile enough for race wheels or training wheels.

The tiny size of Black Chili particles allows them to mold to variable road surfaces more readily. It gives the tire greater ability to conform to imperfections in the road surface for excellent grip in demanding situations such as high speed cornering. 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.

The Black Chili particles are also literally more flexible, which reduces the rolling resistance of the GP 4000 S II. The Continental GP 4000 S II is available in 700x23 and one color; Black/black.

Best Tire Available Period

In our cycling group ( 45 cyclists) 90 per cent of our
Riders use the 4000s no complaints just the best tire on the market. We tend to use the
700 x 25s and let's hope they keep making them.

Best all around tire

  • Familiarity: I've put it through the wringer

GP 4000's are by far the best all-around performance tire on the market. There are tires that may be more durable but they don't roll as fast. There are faster tires but they aren't as durable. The GP 4000 combines both characteristics marvelously. Go for the 25's if you have the space in your frame and fork. They rolll faster than the 23's.

"Ain't not broken don't fix it"

  • Familiarity: I've put it through the wringer

Not sure what was Continental thinking why they were trying to improve something which was great. The old S was great and did holds well at all conditions I was riding them even on roads with patchy snow/ice (23 mm). Contrary S II is not made for everyday use, sidewalls are like a paper, it doesn't take to much to puncture. 500 miles and you better start looking for replacement. I ride in Colorado (5-7k miles a year) this new version is not what I was expecting at all. I stopped to using them even up front. Two or one star are appropriate in comparison to old version. I ride in all weather conditions on mixed roads, and yes I am heavier guy. 200lb

Durability and Great Traction

  • Familiarity: I've put it through the wringer

Got the 28mm tires first time around. Super nice rolling tire but the 28mm's barely fit through dura-ace brake calipers. Recommend going with 25mm's. Love these tires. I'm new to the road side of cycling so these are the only road tires I've used, but I rarely get flats. They have great cornering grip and roll fast. Got caught in the rain on one occasion and the tires never slipped. Of course I didn't try to push their limits in the rain but I didn't lose traction.

Very Nice and Smooth Tires

Very nice tires comfortable and smooth. Thanks Competitive Cyclist for the advice in selecting these tires. I’m very happy with my purchase.

tried and true

  • Familiarity: I've used it several times

Have been on the 4000S for years and just switched to these. No real noticeable difference in ride, which is a good thing because I loved the older version too. Photo shows the white decals on the side of the tire which are noticeable but not a deal breaker.

Consistent all round tyres

  • Familiarity: I've put it through the wringer

Have been running these clinchers and their predecessors for years. The new Mark II version appears much softer and tacky, whereas the old version would become quite hard over time.
Puncture resistance is good, and I have not had any issues with sidewall cuts as mentioned by others, even after spending time on rough roads and riding on gravel.
Would recommend these as a good value tire.

Great tire at nice price

  • Familiarity: I've put it through the wringer

I run 25s of these tires on my road bike. I'd recommend the move from 23s to 25s for just about anyone (weight increase is marginal and ride/rolling resistance are better). I've had them on for two years with some moderate riding on gravel roads included...very few flats. Conti definitely has beefier tires available, but I've really been impressed with the toughness of such a light tire.

The standard for all my bikes

  • Familiarity: I've used it several times

You get consistent performance and comfort riding these tires. Yes they do not last for ever but traction is excellent, rain or shine.

You can buy speed at a reasonable price!

  • Familiarity: I've put it through the wringer

My wife and I have ridden this tire more than any other. I found an extra 1mph or so the first time I mounted them. Several comparison reports show they are the fastest road clincher that is still durable and suited for a few thousand training miles. Flat resistant and have experienced good tread up to about 3000mi. Not flat proof.

If there were a better clincher in this price range, I would ride it. There isn't. Buy the 4000S II.

Best all around tire. Takes a beating and loves it.

Great all-around tires

  • Familiarity: I've put it through the wringer

I've tried multiple brands and models of tires through the years, but I always go back to the Conti's. They're light, roll great, and wear really well.

All Time Classic!

  • Familiarity: I've put it through the wringer

These tires just plain do everything well. Handle well, wear well, don't ever seem to give me any grief going on or off the rim and they even look good (for what that's worth)! Continental quality is seond to none and easy to trust. I'm like others, I enjoy trying out new options, but I keep ending up back at the 4000 GP.
My only other recommendations are the 4-season and the Continental Gator Skins (if you ride in the rougher neighborhoods)

still my favorite

  • Familiarity: I've put it through the wringer

Although I have been running the conti 4000's for several years now I still like to try out some different rubber to make sure I'm not missing out on anything. They are still my favorite clincher tire. They protect as well as anything I've ridden, more importantly performance is excellent, I can train and race on them. I with they lasted another 1k miles but hey I can't have everything.

Very Good Tires!

  • Familiarity: I've used it several times

There are better performance tires out there that are lighter and with a better grip, but at a much higher cost as far as price and durability. For the $, it's hard to find a better overall tire than the Conti 4000 S II. It has a very good combination of performance, durability, and grip (unfortunately I can't comment yet on the grip on wet roads since California has been mired in a horrible drought). Buy them when they go on sale, which is pretty often.

Great racing tire

  • Familiarity: I've put it through the wringer

These are the only tires that I had use since I bought my scott foil 2 years ago. Overall they are great tires for their intended purposed, racing. The tread compound does not last very long since use the black chili formula. A more softer rubber for better performance and grip. If your ride includes a lot of city street riding, I don't recommend this tire but if you just want to ride fast on weekends or in a peloton this is the tire for you.

Not the best, not the worst

  • Familiarity: I've put it through the wringer

For overall performance v durability it's a good tire. but durability is definitely lacking as is the really high end performance. As with most conti tyres, i get sidewall issues. Honestly I prefer Vittoria rubino's as they're cheaper and about the same performance.

So many side wall failures

  • Gender: Male
  • Familiarity: I've put it through the wringer

The 4000s was my go to racing tire in the past. It rolled well and had adequate flat protection. The 4000s II has been nothing but a disappointment. I have had 4 of these tires fail due to cuts in the sidewall that ruin the tire. I am not sure what changed, but the lack of reliability of this tire compared to the original is appalling. Other people I ride with have been experiencing the same problems. The only positive for this situation is that I have discovered the Schwalbe One, which rolls very well and has had phenomenal flat protection for a racing tire. 0 flats in 1600 miles of gravel and cinder covered Ohio roads, including during early Spring when the roads were frequently being treated for snow. The 4000s II rides well while intact, but so does the One. Note the tube popping through the hole in the photo. That happened last Fall, before there was a lot of crap on the roads.

Smaller diameter than the 4000S

  • Familiarity: I've used it several times

I have been riding the 4000s for a long time. I was psyched to see a new version coming to market. I like the 25 mm size. These are considerably narrower than their predecessor. Bummer. I want a bigger tire under me, and this new and improved version has gone skinnier--odd choice for Conti given the trend to bigger tires. The moment I put them on I could see they were not as big as the 4000s I was replacing. On my rims, they measure 2 mm skinnier, sidewall to sidewall. The 4000s measure at 25mm on my rims. These things come in at 23mm. Improvement? No.
