Thanks to its DuraSkin anti-tear fabric, the Grand Prix 4 Season holds up under extreme conditions. In the Paris Roubaix race, the Hell of the North, cyclists equipped with DuraSkin enhanced tyres have the fewest tyre related problems during the race. Incorporating Conti's special wear resistant carbon compound, the tyre is characterised by very good mileage performance as well as excellent adhesion on wet roads and at low temperatures.

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 breaker. Vectran Breaker does not adversely affect the rolling resistance.

DuraSkin

Tyres with DuraSkin sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. The high quality polyamide fabric protects the tyre casing against the worst conditions. These tyres stand out thanks to their brown sidewalls
