32mm on front and back of Giant Defy. A few tires I've tried are close, but none are better!
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 !!
I have used gp 4000 and now the gp 5000 since they first came out. The combination of the price and performance is hard to beat. Inthe last three years of riding rural roads I have had zero flats.
The Conti GP 5000 are my tires for racing and everyday riding. I have ridden on Conti GP 4000 tires for a number of years and really liked them, but the 5000's are even better. I find they grip the road really well in corners and all conditions. They are also faster (less rolling resistance) - so if you are looking for a little more speed try them out.
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.
I've had three pairs of these. Each one last 4-5,000 miles. Arizona roads.
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.
Fast. Comfortable. Puncture resistant.
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.
Best road tire I've found (on good pavement) I use them year round. Only downside is some vulnerability to sidewall cuts but I haven't had that problem with the latest generation. Watch for sales.
Got this when it was on sale, otherwise I would rate it 4 stars because they are a pricey tire, but you get what you pay for and this is all around a great tire.
These are the only tires I ride, a bit pricey but worth it. Great road feel and low rolling resistance and puncture resistant. They grip well in the wet as well, I never have to think about my tires once I put these on my bike.
I ride about 40 to 50 miles per week, I'm clearly not a hardened workout enthusiast but then I'm 65. I have ridden on multiple tire brands for over 45 plus years of riding and I have to say I'm very, very impressed with these Continental Grand Prix 5000 Road Tires. I have not had a flat yet and I have been riding on them for 18 months through rough roads, dry and wet conditions and they have performed superbly. I would highly recommend this tire!
Love these tires! I have been using Continental Grand Prix ever since the 4000S model.Long life, puncture resistance and wear indicators on the tread make it easy to know when to replace them.Even after that, I put them on my trainer for many more miles.
After years of riding Conti 4000's with infrequent flats, I was excited to upgrade to the 5000's. But after less than 200 miles on the 5000, what started as a small sidewall puncture turned into a 3" long tear in the sidewall, separating the bead from the sidewall and making the tire unrideable, even with a section of old tire placed beneath it. Resulted in a very long walk to a nearby bike shop. Happened on a pretty clean country road, probably caused by a goathead, with the puncture hissing slightly for several revolutions before failing catastrophically before I could come to a stop. A failure like this should never happen with a top of the line $60 tire. Very disappointed.
Just mounted them up on my bike. Been riding the 4000 series for the last two years. The firs thing I noticed is the tire, 28mm version, is skinnier than the previous versions sidewall size. With a calipers, I've measure the 4000 series 28-622 tires at 32mm, and the newer 5000 series is indeed what the sidewall says, 28mm. Time will tell if I get the same mileage, great wear, by the way, as what I used to get, and performance. Stay tuned for updatews!
With or without tubes these are faster and I'm a long time GP4000 user. Beware their sizing has changed so the tires are actually as wide as the label. In other words GP4000 28's are the same size as GP5000 32's. This goes for the entire line. By one size larger to get same size as 4000's
My review is short and sweet. I have ridden a bicycle for over 50 years and that includes, road bikes, mountain bikes and hybrid bikes. I have ridden a variety of tires over decades of change and development. My current bicycle is a hybrid (road and mountain). I put on about 7 to 10 miles a day over smooth and rough terrain (sidewalk with some nasty big roots punching through). I have never ridden on a better tire ever!
The tan-yellow sidewalls look great on my black bike. Performance is typical for GP5000 - which is to say good to great.
This tire has legendary status for a reason. Checks a lot of boxes: durability, feel, rolling resistance. Been running this model and its ancestors a long time, have tried others, but always come back to this one.
