Switched from 25mm to 28mm and very happy about it. Run them at 80 pressure and get a much gentler ride over broken up concrete roads.
Be warned, on wide HED Belgium rims, these tires measure 31mm in width (using a caliper).
The 4000s is fast and I have found it durable enough for my year round riding. I have been putting about 120 mike a week on them and run my 28mm at about 85lbs. Love these tires!
Using for triathelons and love them. Roll great, you see them on half the bikes for good reason.
Excellent road tires as they grip on wet pavement and are resistant to the occasionally broken beer bottles people leave behind. They are also resistant to the kiawe (Hawaiian Mesquite) thorns strewn all over the islands.
I've been riding on these tires for the past 15k miles or so. I've had maybe 2-3 flats in all those miles. I ride mostly on county tar & chip seal roads. I've always used size 700x25 but went up to 700x28 the last set. I decreased my tire pressure from about 100 to 90psi. They seem to be more comfortable with little speed difference. Get these tires when on sale, you'll be happy.
Good light weight, that handles the road well
I ride 5-6k miles a year, commuting and club rides. these tires perform very well giving me confidence in descents and cornering. I replaced the rear tire, after a year of riding, as it was getting a bit squared, and the annual Seattle to Portland ride was coming up. I still have not experienced a flat with them.
The Continental GP 4000 S II is a smooth, fast tire. I use it on a Trek Domane for added cush on chip seal roads. The larger (28c) size provides a solid but smooth ride. I can't tell any difference in rolling resistance from the previous 25c tires used. I highly recommend this tire.
I have been riding these tires for years and they just keep getting better. On westchester New York roads they are fairly puncture resistant and hold up to holes etc. When the roads get nice they fly
Go to tire, love the feel, weight, durability. Sticky, good in rain. Year after year, this is the tire I have always come back to.
Did not keep close track of miles on the last set, but somewhere in the neighborhood of 5000mi. Just got a new pair of 23cm on the road bike. Typically inflate 90- 100 psi, on good roads.
I have raced and trained on these tires for many years and they enspire confidence. With average of about 3800 miles a year, I only get one flat per year. Great traction on both dry and wet surfaces.
Good grip, solid handling, decent puncture resistance (Gatorskins are better)
Durability , ride and speed are all at high level.
Great clincher road tire. Only negative is soft side walls vulnerable to cuts. Stock up when on sale.
Have used Continental 4000S II since they hit the market and Continental 4000S previously. Usually get 2500-3000 miles on the tires. 1 tire the side wall blew out with only 250 miles on it. Another blew out with only 180 miles on them. My opinion is both tires were defective in workmanship. Now trying to determine which tire brand to use.
Nice tire except the sidewall failed (tear) after only 1200 miles. No obvious cause - smooth road. Too bad - I liked it otherwise. Seems like it had goodlow rolling resistance on my kind of roads. Won't buy it again because of the failure.
I bought these tires to replace Conti all season tires which I loved in preparation for a race. Have used them for a week. I have not ridden them in the rain. I have noticed that they roll more quickly down hill than the 4 season tires. They grip well on the road. The ride is smooth. No complaints thus far.
This has always been my go to tire. After riding the Gaterskin tire for the winter its even more of a pleasure to get back on the 4000S tires.
After too much research I decided to go with GP4000s for a middle distance triathlon. After several hundred miles tires are still in great shape. It appears there is a reason most triathletes use them - seems like the best combination of durability and speed (not that a tire impacts my speed much). If they are good enough for the pros they are good enough for me.
