ContinentalGrand Prix 4000 S II 700c Road Tire(Return to Product Page)

I always stock up on a few of these tires whenever they are on sale. They are light and durable. I use them for races and training. Rarely will they flat, and that is usually caused by steel wire from steel belted tires that litter our roads.

This is not the smoothest rolling tire. It My last set made it over 3000 miles. For the money, to get a durable fast rolling tire, this one is hard to beat.

I use this product for crit racing. The tire conforms to the corners well and have good flat resistance on the open road.

For past 5 years or longer I have ridden on another brand tire, I was satisfied. Bought a pair of the Grand Prix S II's, and have only one of the two currently installed (on the rear). I immediately noticed a nicer ride, felt stickier too. Definitely a better ride than what I was accustomed to.

I'll go out on a limb without any empirical evidence at all - the tire seems faster. Just a a couple rides and will be changing the front soon - so we'll se about that. Have to give them a season to see how they hold up. But so far - nice tire.

Will try the 25 but have ridden 23 for 1000s of miles with rarely a problem.

Amazing product. These are the only tires Ill ever need or want. As advertised. I only ride about 1,000 miles a year, but no punctures over last 2 seasons. And I ride on some roads. Ill give 5 stars because these Continentals are perfect for me.

Used on my road bike, I usually get close to 2500 miles before replacing

The best durable tires I have ever used. I buy a new set every winter and use all year. 4200 miles last year. Not 1 flat. Also low road resistance.

Great tire. Rolls amazing. Smooth, fast. So far durability feels solid. Bought another set when they went on sale.

I have Conti GP 4000 S on several bikes. They are my go-to tires for my rain bike, road racing bikes and tandem. I have used them in 23, 25, and 28mm widths. I have long loved the feel, traction and durability of these tires. Puncture resistance seems really good, too. The only improvement I could think of is for Conti to make a tubeless version available!

Tire wears very nicely, I feel very safe on these tires on my high end bicycle

Great price & Delivery

Fast tire!!

Awesome grip, decent flat protection, very fast and easy to put on the rim. My favorite race tire by a long shot.

I have had two sets of these tires on my BMC Team Machine SLR01 in the last 18 months. They generally last between 3500 and 4000 miles. During that time I have had only one flat tire, and that was largely my fault, as I was running too low pressure and got a pinch flat. I have absolute confidence in these tires under any road conditions. They cling to the road and never lose traction. I wouldn't put any other tire on my bike.

great handling, great wear, good puncture resistance

I, and many others, consider this the best road tire around. Since I went from a 23 to a 25 (granted only one season), I've yet to have a flat. Very reliable.

Used on my road bike, the tires seem to last for at least for most of the year unless I ride over something really nasty

No complaints. Excellent in rain, as well.,

I've been running on Continental Grand Prix tires all year, ridden almost 2,000 miles on them and they're still in good condition. The tires are fast and smooth and i'd recommend them to anyone.
