Grand Sport Extra vs eRuban Plus review

Features

• 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).

• NyTechBreaker

  Nylon fabric in the performance sector

  Our new NyTech Puncture Protection has been developed based on the proven Continental SafetySystem Breaker. Its nylon fabric makes it resistant to punctures and cuts like Kevlar reinforced high strength fibres, but offers lower rolling resistance and reduced weight. The NyTech breaker sits between the SafetySystem and the PolyX Breaker® as a more effective puncture protection casing in the performance sector.

• 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®.

• E50

  Suitable for E-Bikes

  For our E-Bike tire 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.

• Plus Breaker

  Maximum safety

  Between the tread and the carcass, a puncture protection of highly elastic special rubber is used. This practically impenetrable puncture protection successfully defies all types of foreign objects from getting to the inner tube below. Even a drawing pin cannot get through. Tires with Plus Breaker can be seen in almost every segment nowadays: Whether racing cycles, MTB or city/trekking, the Plus Breaker guarantees maximum safety without negatively affecting the cycle properties of the tire. The consistency of the breaker has been adjusted so that the tire does not feel spongy when cornering. The Plus Breaker is true puncture protection. Please read the air pressure instructions!
