Completely renewed, sporting a dynamic tread pattern design. Matches with a race bike, as well as a classic city road bike. Available in a wide range of dimensions and colors. PureGrip 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). 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.
