    Grippy and puncture-resistant.

    Continental’s Black Chili Compound is famous for its unusual combination of grip and durability, and the Grand Prix 4000 S II Tires are the company’s flagship road product. The GP4000s, as they’re commonly called, can be found under riders and racers from seasoned pros to weekend warriors. Continental has upgraded the long-running GP4000s with a strong, puncture-resistant Vectran yarn made from liquid crystal polymers. This yarn doesn’t cause any kind of "dead" feeling in the tires, and it keeps pesky rocks, glass, and thorns away from your tubes.

    • The most popular racing tire we carry
    • Increased suppleness reduces rolling resistance
    • Unrivaled traction and road feel
    • Vectran technology reduces puncture risk
    • You know Conti's GP4000 tires are the best, and they know you know
    • Item #CON000B

    Great tire, some quality control concern

      Love the tire, ridden heavily on my tri bike but now that I have some wear on the treads of the current set I am finding bubbles in the rubber. No issues yes, but definitely concerned about the structural integrity based on what I am seeing (image below).

      Great tire, some quality control concern

      My primary tire

      • Familiarity: I've put it through the wringer

      Been using these for years. Great feel, the durability is excellent. I am not a light weight finesse MTB instincts some times get the best of me.
      Just jumped on the deal offered at Backcountry today so I have my next set ready. The tires do last a long time but my current set is finally reaching the end of their service.

      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.

      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 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.

          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.

          When will you offer the 700X28 size?

          When will you offer the 700X28 size?

          At this time we do not have an order in for that size. Maybe check back in a month or so to see if we have placed an order for that size. If you would like to explore similar tire options in that size feel free to chat with a Gearhead online or call us at 1-800-409-4502
