Great Tire for the price!!
Love the tire! Use it on my road bike and carry a spare as well.
No idea I have not used them but I will
I haven't had any negatives. These have been just as advertised. Great rolling, great cornering, good flat protection, and my new go to everyday road tire.
Best tire we have found.
I'm loyal to the Contential Grand Prix and this tire is the BEST yet. Rolls smooth, no flats for 2 months now. Perfect tire for daily riding and can use for racing too.
Love these tires. For whatever reason, these tires make me want to go faster. Incredible rolling resistance and super sticky. Favorite tire right now.
Toughest and fastest tire Ive ever used
Less flats
This tire has the best rolling resistance of any clincher tire I have ridden.
Just purchased these in April - 2nd set on my Trek Emonda SL6 w Aeolus 5s - I purchased the reflective tires this round - they are awesome at making you even more visible & my first ride out, I picked up a carpenter's finishing staple. No tube puncture or anything! I highly recommend these. I'll probably upgrade to the 5000s on the next round.
I have been using GP4000 tires since their introduction, for a total of somewhere in excess of 25000 miles. They are tough, light, and terrific at cornering in all road conditions. I generally get about 3000 miles out of a set of these tires before the wear dimples disappear. This riding over largely chipseal roads. The only problem with these tires has been pointed out by a few reviewers, has to do with the sidewalls being somewhat fragile. I have only had to throw away one tire due to a sidewall puncture. It was upsetting due to it being a brand new tire, but I doubt that any tire would have survived that particular road hazard. I consider these to be about the toughest tire out there. I will continue to use them as long as they are available.
I've been using Grand Prixs for about 10 years. Great traction & few tire-related problems.
While the 5000 was recently released, and is 'new & improved,' there was nothing wrong with the 4000 IIs and the reduced price commonly found on them now makes them a really great deal. I will continue to run them on my road bike for years to come.
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.
The only puncture I've ever had with Conti GP4000s was a pinch flat - my bad. For my road bike, I can't imagine a better investment, especially when they're on sale!
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.
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.
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.
Have ridden on this tire for 18 months in 28 width. Have always ridden 23 to 25 but after doing some more research decided to try the 28's. As with many things in life it's hard to admit that everything you thought you knew was right is proven wrong when you finally give in and try. These tires are not slower, they might be a little heavier but not enough to make a difference for most riders. Their toughness is amazing. I finally decided after a summer of riding to buy another set in preparation for spring. The current set has multiple slices that would have flattened other tires.
Like many cyclists, I've tried a lot of different high performance tires looking for that one tire that excels at everything. In the end, I use GP4000's on all of my wheels. A few tires have a more supple ride, a few corner better. Other tires are miserable to fit or have weak side walls or get lousy mileage or are prone to flats. GP4000,s just inspire confidence. They corner well in wet and dry, I get excellent mileage, (3,000 mi. plus), average about 1 flat per year, never had a side wall problem and they have relatively low rolling resistance. I've hammered these tires on So. California roads and the GP4000.s always get me home safely.
