    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

    25 is the new 23

    • Familiarity: I've put it through the wringer

    25mm is the new 23mm. The larger wheel is noticeably more comfortable than the popular 23 of yesterday. The increased rolling resistance is also negligible so no need to worry there. Solid tire choice for racing or training.

    Why go tubeless?

    • Familiarity: I've put it through the wringer

    These tires roll just as well and grip just as well as a tubeless setup. Don't deal with sealant and get these race ready clincher tires! Especially if your bike will accommodate 25mm tires. Warning these puff up a bit wider on most wheels. I have raced these for three seasons and as my skills on the Crit course progressed these tire kept my grounded. Made with Black Chili " keep the the rubber side down" compound you can rail corners and get to the finishing sprint faster than your race companions. Hope your not afraid of heights, you'll often be on the top step with these tires installed on your race wheels.

    fast and considerably light

    • Familiarity: I've used it several times

    use the tires for racing only, not the fastest or lightest but they provide good grip and puncture resistance at a reasonable price.

    can't go wrong with these tires.

    First new tires I ever bought

    • Familiarity: I've put it through the wringer

    I *finally* bought new tires for my road bike. I was doing the ole' i can get a few more miles out of these bit. Granted I've put more miles in this year that i have in the previous 6 years - it was long overdue! These were recommended by a friend and I do not regret the decision. I ride in NYC out on 9W and these hold up great through the city streets (seriously there's glass and shit everywhere in this city - its hard to always see it and avoid it). Been riding on them for the last 6-8 weeks ~400+ miles and not a single issue.

    Conti 4000 ii 700x25

    • Familiarity: I've put it through the wringer

    Purchased these for my road bike with 55mm carbon rims. I ride varied road surfaces, race, long fondos, and just for fun and also have these same tires on my Tri bike. I've had the 23 mm as well and these feel like they ride a bit better, but that is just feel. I've ran them at 90 psi. Pretty rough getting them on the rims but that's common I undertstand with these tires when reading reviews and my experience. No puncture issues whatsoever and they feel pretty fast. I've always gotten well over 2k miles on these tires. Buy with confidence.

    I Am Going to Have to Give These an "A"

    • Familiarity: I've put it through the wringer

    If companies would drop all the superlatives and tell the truth, they would get better grades in school. However, as they come out with all the VooderSpraken, and if that widget does not go pop, fizz and zaggle, then they are going to take their C+ home to their mum. This tire is an exception. I am 63 years old, how would you feel about your grandfather turning a racing bicycle at 35 miles an hour in the rain on tires that "might" hold that road? Ops, it rained, oh well. These tires are the best all rounders I have ever put to a set of rims. My carbon fiber bicycle is fantastic, but it in truth doesn't really like going over 35mph. At 35mph my bicycle starts to turn into a government worker. That is where it starts to do the Hula. Oh, don't get me wrong; it keeps going, but I don't get too squirrely with it. My insurance against that is this set of tires. Brilliant, and you have to look at how Continental worked the margins to achieve this performance. I will give you a hint. Everybody knows that wind can hit a tire head-on. Okay, what happens when the bicycle is in a turn, heeled over like a 20 million dollar yacht, and the wind, - weird, is actually hitting the tire from the side? If all the tires are designed to "head into the wind" then what happens if one tire company works those numbers like a Japanese high school student trying to get into Tokyo University, and thus also works to maximize aerodynamic efficiency when the bicycle is laid over at speed like a 4 weight fly rod hooked into a King Salmon? In the straights, about the same, yet in the turn, who is going to exit every turn with an X% advantage? Look at the tire closely and their solutions are simple, but pure genius.

    Rides nice, when not flat

      I replaced my OEM Trek/Bontrager tires after about 1500 miles with these. First ride was awesome - felt super fast, good handling, pliant ride.

      But then the flats set in. 3 flats (one because I didn't patch the gash soon enough), on both front and rear (3 total) in the first ~400 miles. Same roads I'd been riding on the OEMs without a single puncture. Not gnarly roads either - sure the usual collection of crud on/near the shoulder/bike lane.

      Anyway, if you like repairing flats these are great tires. If you want a bit more durability, consider other options.

      I have ridden these tires for over 8,000 miles through crap New England roads(including winters). Only one slow flat that I discovered in my garage the next morning. The above reviewer either ran through a section w glass shards(or something else) without realizing.....where any tire would have taken damage...or he is not pumping his tires before every ride to run proper pressure like you are meant to...or he is an unusually heavy rider combined with either of the 2 mentioned possibilities. No way to know for sure obviously.

      What is known for sure is these tires are the pinnacle of great balance between performance/grip, low rolling resistance, and more importantly durability. Not fair to hold anything against this tire because of a one off circumstance. Every road rider is going to get a flat from time to time regardless of the tire, but 3 flats on this set of tires under the first 400 miles....something else is def going on there. I've been riding for about 7 years on these tires and the previous version. About 3,000mi a year. In those 7 years I have had 2 total flats. These are great tires and very durable. We are all entitled to our own opinions but I could not lay off this one. 3 flats in under 400 miles. Something else is definitely going on there!

      My favorite

      • Familiarity: I've put it through the wringer

      These are my favorite road bike tires. I have gone on countless century rides with these with minimal flats. It's a good balance between flat protection and performance. I have a stock of these tires and only these tires for my road bike. For bulletproof super heavy touring tires, I have the Schwalbe Marathon Plus in 700x35mm.

      Great Race Tire

      • Familiarity: I've used it several times

      I use these on my race wheels as well as my training wheels and they are great! I have had very few flats and they seem to hold up great, won't be switching it up anytime soon.

      Best all around

      • Familiarity: I've put it through the wringer

      I don't want these tires on my wheels anymore, the rolling resistance is so low I felt I'm taking too much advantage against my club riders who are not using these tires. I gave other brands a try but I kept coming back to these tires... the durability is outstanding comparing to others.

      The best tire

      • Familiarity: I've put it through the wringer

      To echo many of the reviews here, I believe these are the best all-around tire available. They've got confidence-inspiring grip, solid durability, and wear better than any tire I've ever used. No other tire checks as many boxes as well as the venerable GP 4000S II.

      Best Around

      • Familiarity: I've put it through the wringer

      I love these tires. Although, they are a little heavy, they make up for being extremely durable. I road over 3K miles last summer with minimal flats. They grip the road nicely, which makes me feel confident on fast descents.

      I honestly do not ride anything else. My favorite size is 25 X 700, but I have yet to try out the 28's.

      Ride True

      • Familiarity: I've used it several times

      In contrast with the tires that came with my expensive new bike these run perfectly true. A bit difficult to install. Ride extremely well . Can't comment on durability yet but seem very high quality. Am a recreational cyclist and have been riding for over 50 years so I've used many a tire among other cycling equipment. Owned a Trek when they were hand made in Wisconsin, wow what a bike!

      WRONG SIZE -- More Like 30+mm!!!

        I have run these in the 23mm & 25mm, so when I bought a new bike this winter that had Continental Gatorskin 28mm tires on it, I immediately bought the 4000s IIs 28mm to put on it this Spring -- they DO NOT FIT!!!

        These are NOT "28mm" tires, when measured IRL, they are 30+mm, and rub the frame on a bike that can comfortably run other models of Continental tires that are 28mm.

        I am not sure why Continental would make their 28mm tire over 30mm wide, but they did, so don't do what I did and blow $120 bucks for 1 trip around the block on "28mm" tires that are the wrong size -- unless your bike can clear 30+mm tires -- these "28mm" tires will NOT fit!!!

        A solid standard

        • Familiarity: I've put it through the wringer

        When deciding which tires to put on my bikes, I focus on four main categories; durability, grip, speed (rolling resistance) and weight. I have yet to find a tire that hits all four categories with the same high performance standards as the Continental 4000s.

        Can you run these tires tubeless? Has anyone tried it?

        Don't even think of it, sidewalls too thin and a kevlar bead not carbon. With these tires, you get the best road feel using latex tubes, but if you want more protection against flats, try butyl tubes with 2 oz Orange sealant

        Unanswered Question

        Did Conti change the actual width of these tires? Two of my friends have them labeled as 25mm. One measures 25mm wide, the other 27.5mm. The rim widths are nearly the same. The latter purchased over a year ago, the former more recently.

        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
