Grand Prix 4-Season vs Ruban review

Features

• Vectran

  The benchmark in puncture protection

  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 the 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 bicycle tire 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

  To roll with the punches

  Tires with DuraSkin® sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tires skid along curbs; on touring bikes, they cross continents without wearing out. In racing cycling, they have to endure tough tests such as the Paris-Roubaix. The high-quality polyamide fabric protects the tire casing against the worst conditions. These tires stand out thanks to their brown sidewalls.

Features

• Tubeless Ready

  Our carcass construction is robust and impervious against damage and penetration from foreign objects. The result: versatile, low weight and an attractive design. In addition, tires made using this technology can also be used as Tubeless or with an inner tube.

  We recommend the usage of our Revo-Sealant.

• Shieldwall system

  The ShieldWall system combines the optimum combination of high puncture protection and the low rolling resistance with low weight. This is made possible by an additional, all-round puncture protection layer, which consists of a finely woven cross fabric. This gives the tire a high resistance to punctures and damage. Despite its additional ply, the tire has a very good damping property and a high degree of flexibility to adapt perfectly to the ground. The revolutionary tubeless ready bead allows easy and uncomplicated mounting of the tire. For best results in sealing and in use, we recommend the use of the new Continental RevoSealant sealant.

• E25

  Suitable for E-Bikes

  For our E-Bike tyre we fall back on over 100 years’ experience with moped and motorcycle tires. All of our city/trekking tires are rated to a standard speed of at least 25 km/h. Those tires marked e50 are also certified for S-Pedelecs. With their high quality structure, puncture protection is high and the rolling resistance is low offering protection from premature wear brought about by the additional driving force.

• PureGrip Compound

  The advanced new compound

  Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable – both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia).
