Eliminate compromise in your race tire.

The Grand Prix 4000 S II is grippier, more durable, and faster than its predecessor. That's because Continental is able to improve their exclusive Black Chili just a little bit every year, thanks to their continued dedication to research and development.

What is Black Chili? It's a unique rubber compound with an ultra-dense construction and high silica content, allowing it to deliver outstanding grip and blazing fast speeds. This cutting-edge formula is also optimized for reliability and longevity, making it a great choice when both performance and durability are top priorities. Just like the name suggests, it's only available in black. Luckily, tje new colorful sidewall doesn't interfere with the tire's primary contact patch, so you get all of the benefits and none of the sacrifice.

The GP 4000 S II also features Conti's patented Vectran puncture protection breaker. Vectran was originally developed by NASA in the construction of space shuttles and suits, and Continental has brought its otherworldly lightweight protection to bike tires, making these lightweight tires impressively flat-resistant.

All in all, the GP 4000 S II is Continental's most advanced racing clincher yet, with a truly unique blend of speed, durability, and, now, aesthetics. Thanks to the high-tech materials and years of testing and development, the GP 4000 S II delivers low rolling resistance and superb handling with exceptional puncture protection and higher mileage performance than a typical race tire.

The Grand Prix 4000 S features three fabric plies for a total of 330 TPI, and has a Kevlar folding bead and a max inflation pressure of 120 PSI. This version of the 4000 S II is available in 650c (571 ISO).

The BEST tire I've ever ridden on.

I am on my second set of the GP 4000 S ll tires. I got a little over 5,800 miles on them before I rode over something that sliced the front and I have over 3,400 miles on the second pair. The thing that stands out the most for me is the high quality of the ride. For many years I rode on Gator Skins and would typically get 6,000 miles on a set before I would change them, but the ride is quite harsh. I ride quite a bit of rural chipseal roads and the GP 4000 S ll really take out most of that annoying vibration and buzz - I was amazed! I was able to ride further and faster because I wasn't as fatigued. They are kind of expensive, but man! the ride is worth it.

Great tires and great ordering experience with Bike Tires Direct!

These tires are well reviewed elsewhere and those reviews seem accurate.

In the past I've disliked Continental tires because they've been a nightmare to put on. Not these though. I was easily able to mount these without tire levers.

Great value and a fast, comfortable ride.

a good compromise between weight, size, and road safety.

I've got over 2000 miles on these tires on my recumbent and I have been very happy with the performance. The tire is much lighter than the stock tires that came with the bike, which helps going uphill. On my rims it's closer to a 25 than a 23, which makes for better road contact and a more sensitive road feel, which helps my confidence going downhill at 50 mph. So far I have no big cuts or knicks, and haven't had a single flat due to puncture. My rear tire is close to the wear mark limit, so I'm ordering a new pair right now.

Good tire

I've got 1000 miles on these tires so far, including 5 miles of gravel road, with no flats, nicks or cuts and minimal wear. They grip the road well, and though they are listed as 23mm wide I find they are closer to 25mm on my rims, which gives a softer ride than the similar Kenda tire. A reasonable balance between weight and reliability. I will buy these again.

The money I spent I these tires I could have bought 4 cheaper tires for the same price. These tires didn't last one season
