Have trusted this tire for commuting and training rides for several years. Flat resistant in urban environments and on thorny desert roads in Southern Utah. Low rolling resistance for such a durable tire.
Review by CoppiThat
I've been riding these for a couple of months now and I'm very happy with them. I'd been riding 23s from Vredestein for many years, so these are my first Conti tires and my first time buying 25s. Our roads in PA can be a little rough so I am enjoying the little bit higher volume tire and the overall ride quality. The reflective strip is a nice touch that really does catch the eye but I miss having some color on my tires. That is probably the only regret I have about these so far. If you want a high-quality, high-performance tire that delivers a nice ride as well as good durability, I don't think you can go wrong with this one.

I picked these up for my triathlon bike, which was in pretty desperate need of new tires. The brain trust at Slowtwitch raves about these tires, and I don't know jack about equipment, so I followed the crowd. To my novice eye (been cycling about 2 years), these are a big step up from what I had previously. The handling is really smooth. I live in the country (sort of), and roads are rough. These tires have held up nicely. I'm really happy with the purchase.
Again, relying on Slowtwitch, I got the impression the price could have been a bit better. I did get them on sale at BTD, and they were still a very good price. I would definitely buy these tires again, and from BTD.

Good rolling tire . Had two flats in one day of which surprised me. I run these on two different road bikes with no problems until one particular day. Good wearing tire.
I'll buy again

I am very happy with these tires' durability, combined with performance. They corner extremely well, even at race speeds, and even in the rain. Being 23mm wide, the size I bought provide a minimum of rolling resistance, and they're fairly light as well, while still having the Vectran breaker belt and other layers of protection against glass, etc. I have even had these tires on singletrack for a short distance (a runwalk was taking up the bike path at that point) with no issue.

A switch from 25C from 23C tires has been one of the best changes i have made on my bike since new wheels. Running so much less air in the 25s, they seem to just suck up the standard road rattle.
Continental tires come highly recommended to me by a of friends as a durable, long wearing tire. I haven't really found them to be that flat resistant and in fact i cut one tire beyond use with less than 300 miles on it. I HIGHLY recommend that you buy these tires on line and not at your LBS. I paid $66 bucks for a pair of these at Bike Tires Direct and when I replaced my cut tire at LBS i paid like 78 bucks for one! OUCH!

I normally get 2,000 miles out of these tires. Rolling resistance is great. An important feature is installing tires compliant with tire errors. Unfortunately, finding those arrows can be quite difficult.

Poor workmanship quality blowing out the sidewall. Luck I was not in the pack and not rounding a corner.
Review by Thomas
The 25 is outstanding as far as puncture resistance and smooth ride
Review by CBrewer
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
Review by Igrex
Rides very fast, stable and much more comfortable than other even other continental tires. On my 16mm inner width Ultegra and Carbon rims it measures at roughly 26.4mm at 80 PSI.
Review by Christopher
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.

The GP4000sII is a great overall tire. And to get it on a sale price at BikeTiresDirect.com is icing on the cake.
This is the only tire I use and it works great for all my riding and racing.
Review by Desmond
These are some of the best tires I have ever ridden, I love these Continental 4000s tires!
Review by D
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!
Review by Chase
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.
Review by RobM
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!

Very durable tires and great handling on turns. I have had very little flats with these tires. Tires were shipped to me quickly and at a great price. I highly reccommed the tires and bike tires direct to everyone
