Grand Prix GT vs Ruban review

Features

• BlackChili

  It’s all about how you mix it

  With our unique tread compound, which is produced only in Germany, we have revolutionised the sport of cycling. With the legendary BlackChili Compound we have answered the eternal question of the best balance of grip and rolling resistance for cycling.

  Regular test wins confirm the measureable and noticeable advantages for the cyclist, established in the laboratory and on the road. The latest polymers as well as specially developed carbon black particles and filler materials guarantee unique performance

• PolyX Breaker

  Puncture-defence

  With our PolyX Breaker®, we bring our car expertise to the bicycle tire segment: Polyester has been used successfully for years in car tires and been tried and tested many times. The extremely resistant polyester fibre is woven tightly crosswise. In this way, a very high fabric density is reached which not only makes the Breaker more resistant to foreign objects but is also especially resistant to punctures. The rolling resistance is also not negatively affected by the PolyX Breaker®.

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).
