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 tyres, which are exclusively manufactured in the factory in Hefei (Asia). E25 (E-Bike ready up to 25km/h) For our tyres we have more than 100 years of experience with moped and motor tyres. Tyres with this label are characterised by high puncture protection, low rolling resistance and protection against premature wear due to the additional driving force of the electric motor.
