Continental GP5000 tires are the only ones I use. I put 2 on my bike at the beginning of every year. They always last the 8,000 or so miles I put on them. Use standard tube and they almost never flat. They corner well and ride smooth too.
Compared to the 4000s, these seem to wear quicker. I don't have exact numbers but I think I got less than 1000 miles out of them before they started showing significant signs of wear. I probably could have stretched it out a few extra miles but I started flatting. Other than that, they are a great tire.
I have previously used Michelin Pro 4 & Gatorskins and these GP 5000 blow them out of the water. I ride typically rough country roads with some road debris and gravel. My other tires used I would end up with small cuts after a few rides that would eventually lead to flats. These GP 5000 have provided an extremely tough exterior while producing a supple ride. They corner well and hold their speed. I have them mounted on a Canyon Aeroad with Reynolds Strike Carbon Wheels.
I have been using the Continental Grand Prix 4000 for the past eight years. One of my favorite rides is the Tour of the California Alps (aka Death Ride), a ride in the Sierra Nevada mountains, over five mountain peaks at elevation for 129 miles. The GP 4000 has had excellent traction, and at high descent speeds holds the road well. Importantly, I have gotten fewer flats than I was with prior tires. Now, Continental has come out with the Grand Prix 5000the next generation. Taking their rubber grip technology they call black chili to the next level, so far my experience with the GP 5000 is at least as good as my years of experience with their previous generation. While I dont have the long term experience, my first 200 miles have been without incident and with great traction.
Got the 28c recently, noticeably smoother and grippier than the 25c at slightly lower psi and based on initial impressions, can't say I feel any slower. Cornering does feel more secure and if the 28's are supposed to perform better in wet conditions than the 25's then even better as the 25's worked fine for me in the rain. Will see how long these last. So far no punctures on my 25's after 2000 miles but perhaps I just jinxed myself...
The Continental Grand Prix 5000 is an excellent road tire.
Comfortable, smooth ride, light weight, wears well.
I am on my second pair, from last year, and I ride a lot. Best tire.
I don't think you can go wrong with this leader in the clincher category !
Buy them !!
Good tire. A little better than the 4000. Handles good and seems to roll easier. Only complaint, they seem to cut easier than the 4000. Mileage seems about the same. 2 rear tires to 1 front. On my second set.
The Continental makes for a smooth comfortable ride. They absorb some of the roughness of the road. I also found them to be puncture resistant. I had only two flats all year. For a tire that grips so well in the corners, they wear very well.
After experiencing poor durablity performance with the prior GP 4000 tire (lots of cuts and too many punctures) I started leaving my GP Four Seasons on all year. I have recently tried the new GP 5000s and so far they are a significant improvement. Rolling resistance and speed are obviously better over the Four Seasons, but durability also seems to be improved. After a couple hundred miles, no cuts or punctures. Cornering grip is stellar and stepping up to the 25mm has improved overall ride comfort. They measure 26.3 at 105 PSI, which just barely fits in my narrow Ridley Noah ISP frame, but the ride quality over 23mm versions of the GP 4000 and Four Seasons is apparent.
I've amassed 2600 miles on these Conti GP 5k tires. The rear tire is just now showing the flat wear so time to rotate. No flats (did I jinx myself here?). I've ordered another on sale already. Good value when they are the Deal of the Day.
The Conti 5000s are great. Not only do they roll true to size, but they last for thousands of miles. Put 4000 on a set I installed in June...and now am thinking I finally need to replace them. Only two flats all season...and one was in my driveway! Great value.
I find two things annoying about these tires compared to the older GP4000s. First, there isn't much rubber there to start with, which helps explain the low rolling resistance. But I wonder how long they will last. Second, the tires are narrower than the older GP4000s. This is to compensate for the wider rims in use today. But I liked the width of the GP4000 700x25s. The new GP5000 700x25s are too narrow, but the 700x28s are two wide.
Started using the GP 5000 when the 4000 S II stopped being made. I can't say I really notice a difference to the 4000 S II, but still get great roll with them, and have only had 1 flat in 3.5 years of riding (roughly 8000 miles). Purchased when on sale, and use them exclusively. I am a 205 lb rider using the 23mm version, but like the way they ride and handle.
