Order it to ride a fondo in Panama, the 2017 Ocean 2 Ocean, lots of hills and it was a hot day.
The extra 3mm of the 28mm installed on the rear, helped me put power more efficiently to the road and I was not as tired as I had ridden the route a few weeks before with 2525 and finished in more time, more calories consumed and much more power lost
Had a question about my order and was able to get a hold of a representative right away. They helped me with my question by going above and beyond what I expected. Delivery was fast, the items got to me before my race. I recommend this seller.
As for the tires, well tires are tires to me. I put them on my bike and I race as fast as I can go. I got these onecs based off of others reviews online. They said they were good for races without compromises of super thin tread to cause a flat, and great rolling resistance when paired with latex tubes.
These are some of the best tires I have ever ridden, I love these Continental 4000s tires!
Excellent tire, works well on the road as well as on the American River Parkway. The parkway being a lot cleaner than Sacramento city streets. Ride quality is excellent in wet and dry conditions!
On my first ride with these tires I immediately noticed the suppleness and decreased rolling resistance - these feel fast. I ride through the potholed streets of Seattle and unfortunately have averaged 1-2 flats per week minimum so far. Life is too short to ride on bad tires however, and I have found the good outweighs the bad with these.
These are great tires with a good balance of durability, suppleness, nice rolling, decent cornering, and relatively light weight. I got about 3600 miles on them before my first flat, though I did rotate back to front about half way through. Some of that was luck, I think, because it was my best no flat streak ever, even better than some Michelin Kyrlions I once had, and good a lot of flat-free miles out of. After fixing the flat, I got a several more rides on them, but noticed sharp gravel was working its way into a few nicks in the tires so I retired the set for use on my trainer set up in winter, and bought a new pair on sale. So close to 4,000 miles on those tires with only one flat, and I could have used them further in a pinch because they still had a bit of rubber left on them. On sale, these are great tires at very good value.
Looking forward to using the new set of 4000IIs soon, after the winter debris gets fully washed off the roads by spring rains. I still have my winter wheels on the bike with Continental Gatorskin Hardshells on them, which while very flat resistant, aren't as supple or as nice cornering as the 4000 IIs.
Great tires. I run these on my 3 road bikes with no isssues. Smooth and durable. Will continue to use these as long as they're available. Purchasing from this site was easy and the price was the lowest online. Thanks!
28mm GP4000sII tires have LESS rolling resistance than 25 or 23mm.
If you are like me and use lower pressures, the difference is even more dramatic.
So you get lower rolling resistance and more comfort at the same time!
The reflective sidewalls are amazing! Gone are the ugly logos and printing and in their place is a wonderful, functional, aesthetically pleasing strip of reflective material. Brilliant.
These come in 25mm as well with the reflex if you can't fit a 28 in your frame.
I put over 3,000 miles on the last Continental Grand Prix 4000S. It is easy to install and the wear indicators provide an idea of how much tread is left on the tire.
High quality, light tire, reasonable price. Wears quickly but is expected for a tire in this category.
I have learned not to ride 4000S II in NH winter because of the high likelihood of flatting on high mileage rides. Too much of a gamble. I'm OK with flatting on this tire in decent weather.
These tires have been my go to tires for years now. Super reliable during training and races. Can't go wrong with these tires.
The Conti GP is my everyday tire. Thousands of miles. Rarely a flat. And it rolls meaning its fast. Love these tires.
I've been on Continentals Grand Prix since 1995. There is no better tire for the combination of performance and puncture resistance. Love them. Racing or training, these get well over a season of miles on them (5000).
Great all around tire. Can use it on gravel and race on it. However, it's not the best gravel tire or the best race tire. 25c tire measure out to be almost 27mm on 17mm inner rim width wheel. Run with latex tubes to get lower CRR.
No complaints about this tire. It's my favorite road cycling tires. I use them on Crits, road race and circuit races.
I have tried all the other top brands and they all leave me disappointed, then I wonder why I even tried
them , then I go back to the GP 4000
I have been riding the Grand Prix tire since the mid 90s. There have been several iterations along the way with the current execution being the best yet. I believe the packaging for these makes mention of the fact that Continental is constantly working to improve the rubber compound to decrease rolling resistance while increasing traction and puncture prevention. Normally I would consider a statement like this nothing more than marketing whether I like the product or not, but in this case, I can't help but think this statement is simply true. Living in the Pacific Northwest and preferring to ride in the hills, I find myself on wet, out of the saddle climbs constantly and these tires provide excellent traction even after many miles of use.
Still after all those years it's my favorite tire. Amazing flat resistance. Lightweight. Great grip on dry and wet conditions. And love the reflective stripliner on the sidewall for better visibility at night (it's the law in certain countries).
I ride a lot of hills and mountains..and I rarely have any punctures..I literally wear out the tire.
I have used Continental 4000 S tires for years and have had no problems with flats. The tires also appear to be slightly faster than the Michelin Pros I used previously.
