The discreet coloured bead strip allows you to colour coordinate the tyre to match your bike perfectly without losing the BlackChili tread performance. The GP4000 S II is versatile enough for race wheels or training wheels.
Continental have also expanded the size range with an additional 28 mm version added. This provides improved grip in poor riding conditions, increased puncture protection and greater comfort. The proven aspects of the 4000 S II remain unchanged and handmade in Germany of course.
Vectran™ is spun from Vectra liquid crystal polymer, which results in a thread that is thermoplastic and has multifilaments. This semicristalline material is harder then aramid, has five times higher tensile strenght than steel and in addition, is also lighter than comparable nylon thread.
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.
About Road Race Tyres
These tyres are for racing style bikes that use clincher/hooked rims, these are the most common fitment and hook onto the rim and require an inner tube. There is a wide choice of tyres within this category and the right choice is important. Lighter tyres will accelerate quickly, but will be more prone to punctures so getting a balance is extremely important. If you require a tyre for all round use look for something with puncture protection, an average TPI(Threads Per Inch) and average weight. If you require a fast tyre and speed is the only thing that matters look for a low weight folding tyre with high TPI. If durability is your priority and speed is not so important look towards the puncture resistant tyres and consider going for a wider tyre, these will be less prone to punctures and offer a bit more comfort. For wet road conditions a triple compound or winter tyre is a good choice, these use a softer compound on the cornering surface to maximise grip.
