  • Continental 2 Grand Prix 4000S II 25c Tyres + Tubes

    When you're chasing podium finishes, KOMs, or PBs, Continental’s Grand Prix 4000S II is ready to give you the edge. This immensely popular model was unveiled in 2007 and has now been updated to include the BlackChili Compound - a cutting-edge rubber compound to help you go faster for longer. Coming complete with 2x Continental Grand Prix 4000S II 700c 25c Tyres + 2x quality LifeLine tubes, this is the ultimate bundle to help you prepare for the coming race season.

    For All Weather Conditions

    Featuring a 30% increase in grip in wet condition, a 26% reduction in rolling resistance, and a 5% increase in mileage, these tyres offer the most complete package to racing cycles and recreational cyclists alike. Enjoy the tyre that is embraced by many professionals and ride in comfort and confidence.

    Fast Rolling, High Grip Road Race Tyre

    These tyres feature the impressive Vectran Breaker, which is a high-end synthetic material that has huge tear resistance despite being light in weight and provides excellent puncture protection. All-round, this means that your GP 4000S II tyres can be used throughout the year. The use of the BlackChili Compound delivers top-tier performance as the mix of synthetic and natural rubbers surpass all expectations of rolling resistance and grip.

    High-Performance and Reliable Road Race Tube

    Lifeline's Road Tube provides excellent value for money. The inner tubes have been produced from high quality butyl rubber. An old wives' tale will tell you that if you buy cheap, you buy twice. Not here. This inner tube has been rigorously tested to ensure that there is no air leakage, thus ensuring excellent reliability and durability.

    • BlackChili Compound: Continental refines newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. The GP4000S II uses these rubbers with special nanometric carbon soot particles, which are optimised in shape and surface properties for best uses for the intended tyre. 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.
    • Vectran Breaker: 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 breake and does not affect the superior rolling resistance.
