The Continental Grand Prix 4000 S II is an updated version of the much loved 4000 S. Still with low rolling resistance & fantastic puncture protection it has advanced BlackChili compound for low rolling resistance, high mileage & maximum wet weather grip
|Puncture Protection:||Vectran™ breaker|
|Use:||Road and training|
|Wheel Size:||700c (622)|
Vectran is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran is a liquid-crystalline polymer (LCP). Vectran is spun from melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk, like Vectran, has an enormous tear resistance at a very low weight – exactly the right properties to process into a premium Continental bike tyre as a puncture protection insert. A Vectran Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran Breaker does not adversely affect the rolling resistance.
Continental refine newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. They use these rubbers with special nanometric carbon soot particles, which are optimized in shape and surface properties for best uses for the intended tyre. BlackChili Compound reaches an unprecedented of performance. Tyres with BlackChili Compound reach an unprecedented level of performance. Compared to the previous best Activated Silica Compound, BlackChili tyres have 26% less rolling resistance, a 30 % higher friction value (grip) and a 5 % increase in mileage.
These tubular tyres are designed for tubular rims, these are glued on using tubular cement or tubular tape. They are the preferred choice for serious riders and professionals when all that matters is performance. A tubular is a sealed unit with an inner tube sewn into the tyres casing, this means the tubular is perfectly round in profile and offers a better feel when cornering. Vittoria have introduced open tubulars which are the same design as their tubular tyres but with a bead for use on a clincher rim, these will offer the closest feel of a tubular but the ease of repair associated with a clincher. Sizing is subtly different to clincher wheels and can be a bit confusing as most manufacturers still quote the old imperial sizes. However there are only 2 real sizes: 26" is the same as 650c, then 27", 28" and 700c are all the same size. We spotted this useful article on Bike Radar which explains briefly the benefits and how to fit tubular tyres.
More than 100 years experience in the development and production of bicycle tyres has made Continental a unique company within the industry. Continental is the only German bicycle tyre manufacturer to produce its tyres in Germany. Knowing this serves as a mighty incentive to our engineers and everyone else involved in the manufacturing process to constantly strive for further innovations. In our technology and development center in Korbach, we are constantly developing new revolutionary technologies such as the unbeatable Black Chili Compound and the ultimate Vectran™ Breaker anti-puncture technology, both used at the top end of race sport. These technologies demand sophisticated processes to ensure our legendary end-product quality, and these innovations as well as the new “ProTection” and ”RaceSport” technology for MTB tyres, can only be manufactured in our factory in Germany – “Handmade in Germany”. In order to offer the best tyre for any application, we rely equally on dialogue with our professional racers, hobby cyclists and everyday bike riders. This results not only in high-end products for top sports applications such as the new Podium TT or the revolutionary downhill tyre “Der Kaiser”, but also tyres for everyday use like the new innovative combination EcoContact/EcoContact Plus as a companion to the latest e-bike trend. As a global player, Continental also maintains high-tech production facilities outside of Germany, where Continental tyres are produced for you with an equal degree of care and dedication. One thing all Continental bicycle tyres have in common is that they are developed in the technology center in Korbach, Germany, where they also undergo strict inspection. Our heart and soul is behind the phrase “Handmade in Germany”, with all of its products and technologies.
