A friend recommended these tires to me and I've loved them. They have tiny marks in them for you to be aware of how much wear they've gone through and know when to replace. Didn't get the reflective kind but I think I will when shopping for new tires. Also rode in rain and they performed GREAT.
I bought these to replace a set of Schwalbe Marathon Plus tires specifically because I was looking to reduce weight and rolling resistance. Based on research, this tire seemed to check both of those boxes while still providing reasonable puncture resistance.
These tires run incredibly smooth and effortless. As for puncture resistance, I just returned from a weeklong bike trip covering 500 miles of rural roads littered with sharp rocks and steel belted tire shards and didn't have one puncture. I even did a little gravel riding (less than 10 miles). I cannot comment on traction in the rain as I plan to use my Schwalbes for winter commuting, however due to the low weight and very low rolling resistance, I very highly recommend these tires for any type of distance riding (multiple day trips, or centuries), they exceeded my expectations.
Conti GP 4000 S II, great all around tires. I've been using these for racing and riding for the past two years. I would say I get about 2000-3000 miles out of a tire, so they do last a good while. They handle great and are nice and fast.
They also provide very good puncture protection for a high performance tire. I know there are other 'racing' tires on the market, but they are very light and thin and certainly put you at risk for flats. From my past experience, there are few things that take you out of a race as fast as a flat tire.
If you balance price, performance and protection I don't think there is currently a better tire on the market.
I have been riding for over 40 years and tried many different tires. The Continental Grand Prix 4000 S II 700c Road Tire is one of the best for wear, flat protection and cut protection. I usually get 4000 miles out of The Continental Grand Prix 4000 S II 700c Road Tires.
I run the Continental Grand Prix S II road tire on three of my four road bikes. They simple are the best tire for the money. Good rolling characteristics, puncture resistant and long lasting. I have tried other brands with no where the success of these fine tires. Highly recommended for your road cycling both racing and training.
This tire has just the right amount of road-gripping firmness while delivering a very comfortable ride. I'm very happy with the feel and handling. Its a big improvement over what was on my road bike previously.
These a long lasting, durable road tires that perform great and live up to the hype. The longevity of these tires also make them a great value. I use them on a daily basis for training rides in all conditions. Because of geographic considerations where I ride and live, I typically climb 3000 ft. on any given ride. These tires provide light weight for climbing and great stability when descending Highly recommended.
Running 28s on a Specialized Roubaix (2014 carbon frame) they rubbed. When calipered at 100psi they read 32mm. Changed to the 25s and had perfect clearance. The 25s measured 27mm at 100psi.
1400 miles in 6 months (40-100 F) on smooth to chipped surfaces with occasional pot holes
No issues and minimal visual wear
the continental gp 4000 sII road tire is a very good tire - perfect for the winter in the PNW where the roads are wet, and the shoulders littered with debris. These tires feel great, and are durable enough that I'm not worried about flats yet. So far, about 500 miles on them and i am very happy. And bonus!, the 28mm tires are actually 29mm when installed on Mavic Open Pro rims.
Switched to Continental GP 4000 after years of using Michelin Pros. Liked Michelin Pros because of their grip, giving confidence on speedy turns, but prone to flats & quick wear. Rarely got more than 2,200 miles on a pair. In 16 months on Continentals, only one flat, & got 4,800 miles on first pair, making price premium over Michelin's well worth it.
Ride about 120 miles a week on 3 rides. Dont like changing tubes on the road. These tires when fairly new offer excellent flat protection along with a great ride. Swap them out before the wear dimples disappear.
Had to replace an almost new front tire at home due to sidewall damage. A gator skin might have been less vulnerable to this unseen road hazard.
That said will stick with this model. Buy them in pairs when on sale.
Well, out comes the GP 5000 for 2019, but I still look to the 400 for proven performance. You can't beat this tire reliability, grip, strength,....it has it all. I'll tell you how it lasts when I reach the 10,000 mile mark!
This is very predictable tire. I performs great on the dry and on the wet.
I really value the wear like predictability. I typically get about 1500 miles from
a pair of these tires. I weight about 175lbs and I i climb about 100K ft a year.
After abandoning other brands since they were very unpredictable as to there
wear out cycle, these are the only tires I will run. I ride about 1500 miles a year.
