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.

Move Over Losers

  • Familiarity: I've put it through the wringer

After putting a couple thousand miles on these tires I decided it was time for a review.

First of all.. if you've got deep dish wheels and don't have a lot of experience putting on tires.. You may want to take them out of the box and lay them out in the sun in as much a circular shape as possible. This helps a lot. I was able to get them on with just my hands & a bit of brute force.

This is a long lasting tire. I would not put anything else on my bikes. There's a reason its the most popular tire on the road for racing, century rides or training. Yes, it's expensive but the performance and puncture resistance is sooo worth it. Changing from the stock tire that came on my first bike to the 4000 S was a night and day difference in feel and handling. The center of the tire has extra rubber that dampens the road imperfections and I assume aids with puncture resistance as well, 1 flat in three years. It's also probably why they last so long.

Move Over Losers

I have a question related to the 25mm tire on your 404's. I built Reynolds assult SLG wheels this year and also have a pair of HED Ardennes + SL. The HED looks like a wider rim, even though both noted 25mm,
Having 23 mm GP 4000 on my HED wheels lays them out at a nice 25mm width, Happy with that.
I built the SLG's with S works tires (2 for 50$ special) in a 24 mm. They mounted at a true 24 mm on this wheel. I have burned the rear one out and replaced w/ a new 23 mm GP4000 as usual. I have always read these to be somewhat bigger in 23 or 25 so I stay at 23 and a bigger/wider wheel.
Mounted new on the SLG wheel, they measure 23mm though. Hmm, maybe they will widen as they get used but i'm considering the 25mm instead, as you have.
Can you tell me how wide that 25mm tire lays on your wheel? Most say the 25mm tires opens to a 27'ish width, where the 23 stays more true to size. My concern is I ride a Ridley Noah and it can be tight in the rear, 27 would push it. Thanks for the info and sorry for the length.

Great Tires

  • Familiarity: I've used it several times

First ride on new 700 x 25 tires. Much smoother ride than the tires that came with my Cannondale Synapse Carbon bike. Those were Mavic Aksium. Encountered several streets being repaved and the tires handled those roads well. Even when standing to go up a hill, I felt a little more give in the tires which made going up the hill easier. Probably due to lower rolling resistance. I had one high speed turn on my ride and I felt like the tires had a solid grip on the road and it turned into a non issue. Highly recommended and $20 cheaper than at my local store. Let's put it this way, these tires made riding more fun.

What size did you you put on the Synapse? I also have a Synapse and am looking at these tires. I've got the Rs11 rim though. I've heard that they may be fatter once installed. I was hoping to get a 28 on but the 25s might be the largest to fit.

Great Riding Tire

  • Familiarity: I've used it several times

I've not had much brand loyalty in the past few years, buying the best tire that I could get at a good sale price. Generally I found that all the tires in the class of the Vittoria EVOs, the Vredestein Fortezzo etc. were basically the same. Then I bought the Conti 4000sII at a great sale price. These tires outshine all the others that are considered race tires. I bought the 700X25, pumped them up to 100 rear and 95 front (I ride the Hed Ardennes Plus LT wheel) and found the ride to be exceptionally smooth and fast. I can't comment yet on durability (honestly, we don't expect great durability out of a so-called racing tire) as I only have about 400 miles on the tires.
I now will have brand loyalty- these tires are my go-to brand.

Did you try the 23 on the HED wheel to see how it fit compared to the 25?
I have been running Ardennes and now have the plus SL. Trying to mount my past model 23, S model and S2 model, both were super hard to mount. In fact, I pinched a few tubes in the process, and I'm not new at this.
I'm concerned that the recent model is tough also.....

To Jake
I have mounted some Vittoria and Vredestein 23s to the Hed wheels and found it very difficult. I think it is due to the width and depth of the wheel rather than the size of the tire. Even the very experienced mechanic at my bike shop found mounting a 23 tire to the Hed wheel very difficult

Always dependable

  • Familiarity: I've used it several times

The 4000 is a case of not fixing something that isn't broken. If I need new tires I don't even think of trying anything else. I did move up to a size 25 after years of 23 and they are great. I'm not sophisticated enough to note any specific differences between the 23 and 25 on the road, but the 25s seem very stable and grippy in the corners. And my Cannondale Synapse had plenty of room for the wider size so I'm happy.

The one I keep coming back to...

    In line with the other reviews, this is the best all around tire I've found. It's the right combination of light, low rolling resistance and durability. It may not be the absolute best in any of those categories, but it is close enough to the top in all of them to make it my continuing choice for all my riding.

    These do run a bit wide. I tried 25 mm on my 2012 Cervelo R5, and it fit, but the clearance was very close. Too close, so I went back to 23 mm, and on Zipp 30 Course rims, the tire measures 25 mm wide when mounted.

    The 25's will likely fit on newer frames, but just too tight on the older R5 frame. Other than, no issues at all. Great tire.

    Love this tire!!!

    • Familiarity: I've put it through the wringer

    I bought a pair of these in 25mm width and put them on my bike replacing my old pair of Continental Grand Prix 4000 S Tire in the 23mm width. Over 2000 miles on the old pair. Since I don't race often the 25mm better suite my riding style of weekend warrior and century rides. I keep them inflated to almost max PSI, which keeps them rolling FAST. They grip great for me when I am flying down a canyon at 50mph+. I'll buy another set for sure once I wear down my current pair.

    Great Tire, No Complaints

    • Familiarity: I've used it several times

    This tire has a great feel on the road.

    Gave it a very light sanding with 300 grit paper before the first ride to get rid of any release compound. Seems to have reliable grip.

    Goes on the rim with average difficulty - not easy, but not hard either.

    Time and Time Again. The BEST tire.

      We're all cyclists. We all have our go-to products. There is no reason to run another clincher. I've tried other tires, but keep coming back.
      These are the best overall. Sure, some may be faster rolling, smoother, grippier, longer lasting, or puncture resistant. But none check all of those boxes as well as these tires do.

      love it!

      • Familiarity: I've used it several times

      rolls really well!! switched over from the gator skins and i could not believe the difference. i've put about 500 miles on these so far and will never go back. Absolutely love them

      This tire is a mainstay -- lightweight, durable, and rolls/corners well. The 25 width makes for an especially comfortable and fast ride.

      Love It!

      • Familiarity: I gave it as a gift but have feedback to share

      Mother always knows best for her bike! Fantastic tire, love the feel, love the grip and it keeps my bike low in weight. Definitely would recommend this tire to anyone who wants a great all-around durable tire.

      Rolls - Corners - Grips

      • Familiarity: I gave it as a gift but have feedback to share

      I have been riding this brand of tire for at least 25,000 miles and have had 1 flat over that time. Currently riding the 700c x 25mm up from the 23mm and love the way this tire rolls, corners and grips. I don't race anymore but put in a lot of serious riding and climbing and have never thought about going to another brand of tire. You can't go wrong with this one, guaranteed! Coming down the mine road in Park City at 60 mph on these and never worry about a blowout or losing traction. Buy this tire and you will never go back to anything else!


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

      I bought a pair of these based on the solid reviews. Unfortunately, I had a sidewall blowout on only their second ride (less than 50 miles in). I was riding 25mph in a straight line on smooth pavement and the rear sidewall blew with a very loud pop. Luckily I was able to stop quickly before damaging my rim. Sure enough there was a 0.75" tear on the sidewall. Can't imagine what if it had been the front tire that blew. While they are fast and light tires, I need to be able to actually ride on them to do me any good, so for me, they are not recommended.

      23's for the TT beast.

      Soft rolling and confidence in the corners. Great race tire.

      23's for the TT beast.

      Thanks for the review Sterling! Super helpful to get this feedback out to the community.

      Amazingly sticky

      • Familiarity: I've put it through the wringer

      Previous to using this tire(had the conti ultras) I was very nervous around any kind of corner. Now...I'm party sure I could go straight horizontal with these round bits of amazingness. I ride these all through the race season, 23's on my TT and 25's for the road bike. I'm constant,y impressed by there grip in tight/fast corners as well as the durability. I generally get 2500-3000 miles out of a pair and I could probably stretch that even further. Are they pricy?...yes, but backcountry has had some great deals on these. When they go on sale buy them up!

      Amazingly sticky

      Confident descents...on clean roads.

      • Familiarity: I've put it through the wringer

      I'm a climber, which also means I'm a descender. This tire, thus far, has given me the most confidence when rounding the turns and switchbacks. On some long mountain descents I've topped out at 53 mph and the turns are smooth with a crisp grip. I can lean confidently under standard dry conditions, more so than other tires I've tried (only 2 others, Vitorria and Michelin). However, other riders I know swear by a particular Vitorria model. I think it's up to the rider to find out which tire suits them and their riding style and conditions. But the Conti 4000s II should be in the running.
      My only drawback is that the sidewalls are really thin, and therefore weak, so as long as you don't find yourself on a dirt trail, it should be ok. I have to admit, in the winter, when the snow plows dump a ton of salt and gravel on the road, I do find myself uneasy with all the debris this renders, and I am constantly thinking about the pebbles hitting the sidewall. But that's a winter problem, and I have reduced climbing during the winter anyway.

      I have the 700 x 25 on Enve Smart 3.4 wheels.

      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.
