Member  1748     Exton, PA |  Subject: conti 4000 or 4000SEveryone says to get the 4000S not the 4000 however I found this from bike tires direct that says the black 4000 is the same as the 4000S. "The Grand Prix 4000 S is actually essentially identical to the black version of the standard Grand Prix 4000 model. The "S" stands for "Schwartz," the German word for Black, which is fitting, because like the black GP 4000, the GP 4000 S benefits from Continental's top rubber compound, an exclusive material which cannot be produced in colors. They call it Black Chili, and it's an incredibly dense rubber, made up of particles roughly ten times smaller than those typically used in bike tires. This state-of-the-art material increases a tire's ability to conform to (grip) the road, while also increasing durability. The Black Chili compound is also more resistant to UV rays, helping it to resist cracking and premature tire wear. " True? |

Elite 7783  PEI, Canada | Subject: RE: conti 4000 or 4000S http://bikeblather.blogspot.ca/2013/04/more-continental-gp4000s.html It has the Black Chili compound but still doesn't roll as well. If you look at the CRR charts he has, it's about 6 watts slower (for 2 tires) vs the 4000s. |

Extreme Veteran 3025 Maryland | Subject: RE: conti 4000 or 4000S That comparison is a 23mm GP4000S to a 20mm GP4000. That is not apples to apples and does not answer whether or not the 23mm GP4000 would be as good as the 23mm GP4000S. |

That is not apples to apples and does not answer whether or not the 23mm GP4000 would be as good as the 23mm GP4000S. So if the CRR testing was not apples to apples, all other tech data is saying they are the same tire as long as you buy the black GP4000 Correct? |

Pro 5892 , New Hampshire | Subject: RE: conti 4000 or 4000S My understanding is that it's not identical products. Continental added Black Chili to all the 4000 tires, but that still doesn't mean it's identical between the 4000S and the 4000. |

Continental added Black Chili to all the 4000 tires, but that still doesn't mean it's identical between the 4000S and the 4000. They did not add the black chili compound to all 4000 tires. The BLACK GP4000 tire has chili compound. The colored tires do not have chili compound and have a higher rolling resistance. The Black GP4000 tires appear to be the same as the GP4000s tires, continental has apparently also said they are the same. I do not believe I have seen roller testing to confirm this. |

Elite 7783 PEI, Canada | Subject: RE: conti 4000 or 4000S More data. http://www.biketechreview.com/tires_old/images/AFM_tire_testing_rev9.pdf The 4000 with a latex tube = 18.9 watts/wheel. Granted, it doesn't specifically say if it was a black one or not so I guess it's not conclusive. 4000s with a latex tube = 14 - 15 watts/wheel depending on the tube and the wear of the tire. |

I think moral of the story, ride the DP 4000S to be safe. (or the Conti SS on narrow rims) |
