I usually ride the Gatorskin's, but no more. This tire is around a 10 watt saving.
First of all, I have bicycled consistently for 59 years (I am 66 now), including racing in the various categories on various single and tandem bicycles (and wheel sets). I learned how to repair sew-ups when I was in my teens and have used probably every tubular and clincher tire on the market. Other Continental tires never gave me any problems. These specific tires-2 in a row using different brands of tubes-blew out while riding around 45 miles. I purchased 2 tires initially, for the front and back. While riding, the tire literally separated along the bead (first time I have experienced that) and subsequently the tube blew. I reordered the same brand, using a new tube, and after about 45 miles, this tire also blew out-separated along the bead (same place, same problem). This was not the case of a pinched flat or underinflation or torn sidewall or bad tube (I used two brand new tubes, different company-and not thins- and the right size). So, I concluded that there was a manufacturing flaw. I will not give up on Continental tires but will give up on this specific model.
My go to tire! Great traction and a good balance between durability and performance.
My only issue is this tire is prone to sidewall punctures which renders the tire unusable.
I decided to try these tires instead of the 4 Season. They handle better and are still very durable and puncture resistant.
These tires are the best on the market today! Theyre fast & smooth as well as long lasting!
Use on the front and rear road bike...best tire in all respects... maybe only drawback -- THE WEIGHT....
I bought these as my everyday tires and for an upcoming ride across the length of Kansas. 565 miles, some of it on secondary roads, not flats, no problems.
I have been riding on Grand Prix 4000 for many years! I have never had any problems and I am 210 pounds.
I normally ride around 3000 miles each year. Not too bad for 75?
I just switched my front tire to the rear only because I like to keep a new tire on the front. The tire I moved had over 4000 miles on it and still had plenty of mold dimples showing!
I have read several reviews on this tire that says that they dont last?
I am heavy and ride rough Virginia roads and even some gravel roads, but these tires hold up for me! Just one old farts opinion!
I have tried many tire brands over the years but in the end I always come back to the 4000 S. Rolls great and is far more puncture resistant than almost anything else I have tried except perhaps for Conti's Gatorskins
These tires ate awsome. They were delivered right on time. Easy to put on. I have put about 200 miles on them no flats. And the bike handles better and is actually faster with these tires on it.
Performance and rolling resistance are excellent. My only issue is this tire is prone to sidewall punctures which renders the tire unusable.
You cant go wrong with this Continental tire. It is one of the most durable tires on the market and it easily compares to the S-works cotton tire in speed
Great
I like everything about these tires, and there is nothing I can complain about.
I got a new, carbon bike which came with Gatorskins.... good bullet-proof tires, but heavy. Seeking weight and rolling resistance advantage, I went with the Continental GP 4000 S IIs and have been loving them. Along the way, I also went with 25s (having ridden 23s since Jesus was a child) and am so glad I did!!! Maybe I'm getting old, but skinny tires and now a thing of the past for me. These tires are fast and smoother than a baby's bottom!
So far this is a good tire. Rides well and handles the cracks and black top bumps and holes well.
Performance and rolling resistance are excellent. My only issue is this tire is prone to sidewall punctures which renders the tire unusable.
This tire has treated me very good thus far, feels very fast and has been solid (knock on wood).
Bought these to ride for the May bike more challenge to swap out my wider winter conti 4 season tires. They feel faster with less rolling resistance (28mm) and are lighter than the 32mm 4 season ms I ride during the winter but Ive experienced 3 flats during the month of May with 464 miles on them. The inside of the tire feels a bit rough (you can see the ridges if you turn the tire inside out) and I think they rub the tube quite a bit which have caused my flats. They arent pinch flats or true punctures but look like more frictionrub causing the flats. May put tireliners on or switch over to slimmer 4 seasons instead.
