These tires are fast, smooth and affordable.
Review by Jake460
I've got a pair of these on my Ti frame road bike. I ride 100 miles a week in cycling season (4000 miles last year). Lots of back country roads, some with good smooth pavement, some chip and seal, occasional gravel. Top speed so far 45mph. No flats in over 4000 miles.
These tires have low rolling resistance and are pretty cut resistant. The tread wear indicators are nice. I like these tires so much I bought 4 more when they went on sale.

I my opinion the best balance of rolling resistance, weight and puncture resistance.Great quality.

These tires perform great in dry conditions, and resist punctures well enough. They offer good grip and feel secure in the corners. The 25's also provide a supple ride without feeling squishy. They are soft and wear relatively quickly, and are prone to damage if you lock up a wheel, but perhaps not more than other racing tires. These are also relatively easy to mount and dismount, even without levers on some wheels. After having tried several other popular brands, I will be riding these from now on.
Stock up when they're on sale, and move fast because popular sizes/colors sell out quickly.

Review by CoMotion
I use only the Conti 4000 series tires for my 100 or so mile per week fitness/local touring rides. They grip well in the wet and provide the comfort and road feel that I like on any paved surface while also keeping the weight down.

Also use Continentals on the cross bike and they've withstood much abuse
Review by Mo-Mo
I use these tires all year for both training and racing. I do a thorough inspection before every ride and rarely get a flat. I'm very happy with them.
My only complaint has been from last years model. I had a side wall blow out at high speed on the front tire. Luckily I kept the bike upright. But, it could have been really bad. The tire was relatively new and it shouldn't have happened. Hence, the four star rating instead of five.
I replaced the tire with this years model and am so far happy with the product.

Supple, comfortable, and responsive. I haven't put in enough miles to comment on longevity. If this stands the test of time I'll give it 5 stars. I'm hopeful that it will be a 5 star tire...

I purchased these on sale (instead of my usual tires, which are Vredestein Gran Fondos or Tricomps). I am used to having little to no issues with flats, I can count the number of flats I have in a year on 2-3 fingers, and it usually after some wear on the tires (the Vredesteins are built like tanks). Within 100 miles I had flats and issues with these Conti's I will never buy Conti again... which is a bummer, as I know a lot of folks swear by them.

I rode Pro3's and then Pro4's in 23c for years. I decided to make the move to 25c and heard good things about the 4000's so after I pinch flatted at 30mph on a corner on the Pro4's I decided it was time to mount up the 4000's. I do a lot of climbing (avg, 1000' per 10 miles) so when I first jumped out of the saddle on a 10% grade I actually looked back to see what was going on. I really felt like I was dragging something and couldn't believe tires made that much difference. I'm not sure whether the move from 23c to 25c made the difference or if it's the Pro4's are that much better than the Conti's but my next set of tires will be the Pro4's in 25c.
The jury is still out on durability but I can say that I flat more often on the Pro4's than the guys I ride with. That said I'd rather replace a tube now and then as long as I can climb like a goat.
Both tires are easy to put on the rim using only hands which is what I prefer to avoid pinched tubes. Although I've never ridden Conti gatorskins I've heard they are hard to put on.
Review by DaveL
This tire is my favorite. They last long and hold the road very well in both wet and dry conditions. Good for roughly 2K miles if you rotate them. I just started riding the 25mm instead of the 23mm. They are even more comfortable on longer rides than the 23s and aside from that I note no performance difference. I live in Colorado and use these tires commuting on my road bike and riding in the mountains. They are relatively flat resistant for this category of tire too. Watch for a BTD sale price and buy them. You will not be disappointed.

Returning to cycling after a 35 year hiatus I purchased a decent quality road bike online. I love the bike, but it came with obviously low end budget tires (Kenda). Previous experience with all manner of wheeled vehicles has shown me that high quality tires well matched for the job are serious plus. Based on numerous reviews and previous experience with Conti's I ordered a set of the GP 4000 SII's and Conti race tubes (700x25C tires, same as the original). Shipping from Bike Tires Direct was very prompt and I mounted them immediately. Mounting was easy and on my rims (Weinmann DP18 700 13C) the tires measure 24.3mm max.width.
Today was my first chance to ride the new tires. It was a cloudy, blustery day with intermittent rain. As I walked the bike out of the door the sky cleared and the rain quit. The sun came out and the roads dried. The wind quit and birds started singing. I flew out of town like winged Pegasus and was shortly skimming along at speeds rarely seen outside of NASA tests. The only downside to the ride was how often I had to pull out to pass cars on the highway. As I came back into town there were people gathered in their yards to cheer as I went by.
When i arrived home there was a telegram from Lance welcoming me to the pantheon of cycling greats. My mailbox has been full of letters from professional cyclists conceding upcoming races. My phone is ringing constantly. I think most of the calls are offers of marriage from super models, it's a little hard to hear over the sound of angels singing. They've even offered to put my picture on a Wheaties box (I declined that one, I don't want to buy a women's bike).
Ok. So that may be a slight exaggeration. I'd let them put my picture on the Wheaties box and deal with the other stuff later. Despite the fabulous tires, I'm still an old slow guy. But these tires are GREAT!!! Compared to the low grade Kenda's they replaced the tires are much more comfortable, have noticeably lower rolling resistance, and much more nimble handling. On the ride today i picked up at least 12 mph on one of my regular rides. On one short, steep descent my max speed was 2 mph faster. The ride was much more comfortable. I had much less numbness in my hands. The handling was much quicker and more nimble. i was actually over steering for the first several miles.
I don't know how these compare to other high grade road tires (I don't have any experience with other tires). I do know that these are light years better than the tires they replace. If you get a set of these tires I don't think you'll be disappointed.

Bought a pair of the new Ess Two to replace my long-wearing set of GP4000S Chili's and was dismayed to find that Continental has changed the size for the updated version. What used to be a generous tire (often referenced as a 24C width) and a perfect fit for my Scott is now just another skinny little sub-23mm tire. Size up, if you can.
Fwiw, I typically get 3000k miles out of a set, and the only punctures I've had over the several sets I've used have been two pinch flats, both from rushing out for a ride and not checking my tire pressure. Would like to assume the new model has kept the Black Chili's epic grip characteristics and Vectran's robust puncture resistance. Five stars for legacy performance and value...
Review by Thomas
I've been asking around my local bike shops, and the cyclist i see on the bike paths, and i have been asking them all the same question What's a good tire i should run?. They all have been steering me towards this Continental Grand Prix 4000 S2 tire, and now i see why. These tires must have glue in the tread because when i take my corners i can feel the bike just stick to the road, i feel safer, and more confident. Also the increase in acceleration is there i know because i can feel myself being faster than the Bontrager R3 that i replaced for the continental's. I am going to use this tire for the rest of the year to see how many miles i can really get out of them. I ride to and from work, and i am a daily cyclist commuter. Not because i don't have a car but because it is better for the enviroment. This was the best upgrade i could have done for my road bike. I highly recomend this tire, and also be sure to get the continental light race tubes for this tire, it will really make the dirrerence. those tubes are only a few grams lighter than the standard butyl tubes.

This is my first venture into full-carbon wheels. I was concerned about getting a tire that would fit the rim without undue force. I've had clinchers in the past that really live up to their name. I'm happy to report that the 700x25's fit with minimum effort. In addition, the tire came in at 205 grams for a total of 295 grams with AirComp tubes. This is lighter than my Vittoria sew-ups (305 grams). The 700x25's are a regal match for the 24mm wide Campy Bora One's - BikeTiresDirect.com current discount makes this a steal, Highly Recommended!!!
Review by Pitts Pilot
I rode the original GP4000S tires for 6 or 7 years before leaving them in search of something with a little better ride quality. After searching around a bit, I found that the Michelin Pro4sc is a better tire for my purposes. They are roughly equal in traction and handling, but the Pro4 has a more supple road feel and has more volume when comparing the 25mm versions. I also prefer the more subtle looks of the Pro4. What I gave up is a bit of longevity and an even larger bit of puncture resistance. Ive averaged 2-3 flats per year on the Pro4 (all in the rear,) where Id get one every 2-3 years on the GP4000s. Thats annoying, so I gave the new GP4000sII a try in both the 25 and 28mm sizes, hoping for the same puncture resistance I loved with, hopefully, a slightly improved ride quality. The decrease in comfort/ride quality moving from the Pro4 to the GP4000sII is definitely noticeable for me and Im willing to accept more flats for a better ride. For the rider who would rather error on the puncture resistance side of what is still an awesome handling race tire, the GP4000sII is outstanding. Worth noting is that the 25 measures a bit over 27mm on my slightly wide rims. The 28 measures a WHOPPING 31mm and is rather tall as well. It would not clear the seat stays on my Giant Defy Advanced frame, which has much more room than most frames. I have clearance for the width, but not the height. If you have tight clearance, take note. The Schwalbe One 28mm is just a touch smaller than the GP 28mm and the Pro4 25mm is only a little smaller than the One 28mm.
Review by Allen
Just a note on this year's sizes. The 28mm version, on a rim that is 21.5mm outside
width (measured across braking surfaces) is 31mm wide.
The 25mm verson on a 20mm rim is 26mm wide.
I have been using a 28mm Conti 4 Season on the same rear rim, it measures 28mm wide.
So I think a 25mm GP4000 will be wide enough on back for my next order.
Review by Jerry P
. . . But the tube didn't. Still scratching my head about that one. They do have a good feel to them, but ridiculous quality control issues. Also had trouble with a 4 season. Don't trust Conti's anymore.
Review by Outdoor Boomer
Had the common sidewall bulge on the beloved GP 4000 I tires and decided to give Contis another try. First, I tried the 28 size on my Trek 5500 frame and miscalculated by about one billionth of a mm and had to exchange for 25mm. Also, tried the reflective wall version. A small increment, to be sure, but I believe the GP II tires may even be more smooth than the earlier incarnation. I believe it's true and it seems to roll just as well too. The reflective side wall is amazing. I do ride at night and sometimes in traffic. ANYTHING that makes me more visible at night is a good thing. When light hits these at night, they light up like a search light! Amazing. Increase your safety and get some, I respectfully suggest.
Exchange was easy and trouble free, btw.
