I'm only giving this tire 4 stars because they were a bear to mount on my daughter's Mavic Cosmic wheels. Just for reference we bought the 25s. I'm not sure if the larger 28s would be any easier but I kind of doubt it. She's good at changing flats (especially for a 14 year old) on the road but if she does gets one either I'll have to come change it or she'll need help from someone fairly strong.
After struggling for a bit and almost breaking my tire spoon I ended up attempting to prestretch them by pulling as hard a I could with my feet and hands for about 10 minutes. Only then could I mount them with a tire spoon. Usually I can get other non-tubeless tires mounted by hand.
She's got about 200 miles on them so far and enjoys the ride quality and grip.
With any luck these will last the spring and summer CRIT season.
First a reminder: With wide rims the norm, conti resized the GP5k to be the width it now appears on ON THE RIM. So your GP5k in 28 is the width of your old GP4K in 25 when it's mounted. Second, there is a bit less tread there- something like .2mm. So obviously the tire is really no lighter than the 4K in the same ACTUAL size. Still, I went ahead and replaced one of my GP4ks in 25 with a 5k in 25. I've ridden it through some pretty bad debris-on-highway-shoulders so far and durability has been great. I'm impressed by anyone getting over 2000 miles out of any tire. I don't try. The 4K would always flatten (wear down) at the top of the tread well before the wear indicator got anywhere near replacement depth and that's when I have problems so I replace early. I thought I'd give up some cornering prowess with the smaller size but didn't notice that either. Race last weekend revealed this to be a fast predictable tire, just like the 4K. No complaints, I'm buying more.
I had been searching for a tire that would not get punctures when I rode vaguely near some piece of detritus with an edge or a point. I had tried other highly rated tires but with no success. The Continental Grand Prix 4K & now 5K do the trick. I imagine they are heavier than some but I can live with that. They are a bit pricey, but since I have to replace them less often, I'm probably not actually spending more. I certainly get a lot fewer flats which makes riding far more fun. As long as Continental keeps up the quality, I'll keep buying them.
I wanted to move from 25mm to 28mm tires for my road bike, so I stayed with Continentals. The ride is smoother and offers better traction in wet and dry conditions.
After doing the tubless scenario I went back to my roots a roll with clichers again. If you run 80+ psi. on your setup you won't be disappointed. Much better tread-life than most. 3,000+ miles is about my average before having to replace them. BTW, they Roll Fast Too!
Like many, I used the 4000s II for years and loved them. This newer version has less tread thickness and costs more. I bought them based on my experience with the previous model, but cannot recommend them due to changes in manufacturing and the price. There are more 700C sizes available in this model and the graphics are smaller and more appealing to me. It is still a good tire but Continental has not advanced the model technologically as much as the introduction of Black Chili compound did years ago.
Got the 25mm pair, not as light, around 260g each on my scale
mounted to 21 internal rim without tools
Measured 27mm with 85psi and tpu tubes
I think it is really faster, I broke my local bench mark 3mile climb PR by 8sec recently
This is my 3rd set of tires. The first set lasted 2700 miles. The 2nd set is in process and I expect to get the same mileage. They are fast and handle well under dry or wet conditions. They are the best.
I am an old guy (74) and have been riding my Road Bike on these tires since they first came out. I ride 150 miles a week on the road here in Florida. The conditions of our roads here is proof we need a sensible infrastructure package. The roads go from really smooth (rare) to almost gravel pretending to be real pavement. Besides that, with the explosion of construction in Florida's fast growing population the bike paths are full of nuts, bolts, nails, and considerable amounts of plastic and glass. It is very difficult to keep from rolling over all that stuff because of the busy traffic at all times of day. All that to say that I seldom have a flat tire riding the 5000's and can say the ride is surprisingly comfortable. I also ride in the rain for a season and feel perfectly safe on the wet roads. I have tried many different tires over the last 25 years and no longer test out any other tires. You won't be disappointed with these tires.
I've tried "faster" tires, and they are great for race day or an epic ride, but I find I always end up with multiple flats over time. These Continentals, with standard tubes, last me an entire season of well over a thousand miles. I find them to be a great balance between fast and durable.
This is my go to road tire, 28mm for my road bike and 30mm for my gravel bike when it's not on gravel tires. The tire handles well, rides well, and can last over 2000 miles. Online prices are reasonable.
Great ride with lower tire pressure, more comfortable.
Plus or minus 10 lbs of pressure for gravel or road, great traction.
I am a daily fitness rider who rides at least 30 miles each morning. This is my second set of Continental Grand prix 5000's and I have been very happy with them. They are resistant to flats, corner well and are very dependable, lasting around 5000 miles even through a Boston winter. Bought them on sale for a good price and expect for them to last me the rest of this year and into next year as well.
Very satisfied with the GP 5000. This is to replace the old one, which has provided excellent service and life. Highly recommended if you're looking for an everyday high quality tire!
This tire has performed like a champ and is my go-to set of skins. Instills confidence on the straightaways and in the corners.
Continental 4000,s 5000s, Black Chili compound are my go to tires. I average 2,300 t0 3,000 miles a season, which is somewhat short in Maine.
Avid road cyclist, loved the old continental 4000, these new continental 5000 are horrible. The wear is ridicules, 1k miles an they are significant wear on tread. All kinds of cuts an side wall shows seperation an thinness. They do ride better an I like the low profile. But not worth the over all wear factor. The 4000 were great last thousands of miles with little or no abrasions. Bring back the 4000 thks.
I've ridden on Conti's for several years. My last set was a 25mm GP5000. This time I went wider to 28mm. The tire really sticks to the road. If you air down a little with the wider tire the ride quality is great. My rims are 19mm internal and when mounted the tires measure right at 28mm or just a tiny bit over. I weigh around 155 and ride with 70 psi front and 75 psi rear. My only complaint is I've had 2 punctures in 1100 miles. I guess you can always complain about the hassle of punctures that can happen with any tire under all sorts of circumstances...however, I was hoping for a little more resistance to the common thorn or glass. I recommend them for all around riding. The weight is also good for the size and all around type use.
I started using Conti 5000s two years ago because of their claims over the Conti 4000s which I was using, especially flat protection. The first day I cut down the sidewall on glass that would have cut anything. Ok, i bought another one to really try these out. Well, 3000 miles later ( on two bikes) they have lived up to all their claims. One complete year with no flats. Subjectively I do believe the ride is slightly better than the 4000s ( not as good as the Vittorias, but they are a poor choice for flat protection here in Las Vegas with lots of broken glass and lots of shredded tire filaments) and they are definitely lighter. I'm using the regular tire and not the tubeless and couldn't be happier!
Have used this and the previous versions for over 10-15 years at least - roughly 35k miles. Average about 1 flat in 10k miles. I do rotate the tires when about 1/2 worn. Ridden in all kinds of weather- excellent grip and reasonable wear- usually around 5000 miles. As a heavier rider 220 pounds- very pleased
