    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

    Disappointed

    • Familiarity: I've used it several times

    I hate to be "that guy" but I've had a really bad experience with my Continental Grand Prix 4000s II's. I ordered my tires last month and the one is already trash. The sidewall ripped and the puncture protection has been mediocre at best. I'm still a 4000s fan but maybe I just got a bad batch. It stinks because I'm not made of money and really can't afford to buy more tires too often. It's not Competitive Cyclists fault at all but it's just where I ordered them so I just came back to write my honest review.

    Disappointed

    So are they going to replace under warranty? Or send you another tire? This is 2 negative reviews on production qc back to back. Maybe someone needs to check on the batch number and call continental for a possible recall? I would imagine that competitive or backcountry would back this tire up as they stand behind their stuff. Am I right?

    William, I'm not sure what's gonna happen but I've contacted Competitive and Continental already so I'm just waiting for a reply. It's a shame because I love these model tires but it's gotta be a bad batch or something because my tires are still very fresh and the tire I had on my front wheel (in the picture) is now trash. Sidewall has blown out and it's frayed by the bead on about 5 inches of the tire too.

    Within two weeks, I had two 4000s II's get catastrophic sidewall gashes--where I had to call for rescue because the tire was ruined. I gave up and now use a Specialized Armadillo in back, all I could get in a hurry. The sidewall was always a weakness, but this was just too much.

    Have run nothing but these for three years. They're very good, but not perfect.

    I got a puncture a month ago on the contact surface of my rear tire one day after installation. Was a minute hole, but that's supposed to be the strongest part of the tire. Flatted once last year.

    I find that flat spots develop between 2K and 2.5K miles.

    The sidewall blowouts are troubling and dangerous. Happened to me in Oct 2015 just a week after I bought my bike and swapped the stock tires for these. Maintained control, but could have been bad.

    Defective

    • Familiarity: I've put it through the wringer

    I was a loyal user of the tire, but two of the last three I purchased have been defective out of the box. Not sure if I've just gotten unlucky or if there is a quality control issue at the factory, but I'll be moving on to something different.

    Mine is also defective. They're still practically brand new and my one tire has already blown out the sidewall and part of the sidewall where the bead is located is also frayed and defective.

    Best all-round training tire I've found

    • Familiarity: I've put it through the wringer

    After years of experimenting with different tires and brands, these are the best tires I've found for daily, year-round, training. I live in Colorado, and we have a fair amount of road debris. Every tire is going to flat, but these seem to have the best balance between road-feel and durability. They're relatively light-weight too, which I appreciate for the mountains. They corner well and their grip is good also.

    Typical high end clincher

    • Familiarity: I've put it through the wringer

    I find that most 120tpi clinchers are all about the same and the Contis are no different. They are very sensitive to inflation levels and tend to smooth out slightly under inflated. Puncture, cut resistance, and durability are good.

    Solid

    • Familiarity: I've put it through the wringer

    This tire has been great. They aren't kidding about the puncture resistances, although I have gotten a couple of flats, I didn't struggle a bit getting the tire on and off which is always relieving. I have had multiple sets and I don't think I'll have the need to roll anything else.

    Favorite Race/Training Tires

    • Familiarity: I've put it through the wringer

    Absolutely love these tires, use them as both a training and race tire. They do not come as a pair, so make sure to grab 2 of them. A little bit on the higher priced end, but well worth it.

    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.

    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
