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.
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
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.
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 Continental tires for about twenty years. They have only improved their products and I appreciate the durability.
My latest tires are 700 x 25 and it has made a noticed improvement without any disadvantages. The ride is even better.
As a heavier rider (200 lbs), but one that likes to ride as fast as these old legs can do, Im always looking for a performance tire, but yet one that will last me 1000 miles. Ive found these tires in a 700c X 25mm the best for me after trying several Michelin & Schwalbe Tires as a alternative. In 4000 miles of seasonal riding my flats are usually limited to 3 - 5 (not bad?).
I have been using Continental Grand Prix 4000 for years for its reliability, superior performance and price. I ride 5K-10k miles a year. I have tried other tires but always found my self gping back to use continental Grand Prix, a bike tire I trust without breaking my budget.
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.
