Tyre sizes are available to cover a range of intended uses. For racing there is the 23 mm width, touring and long-distance cyclists may favour the more forgiving 25 mm size and if the frame allows, a 28 mm version offers more grip, even more comfort and greater puncture protection, attributes which even professional cyclists crave for the Spring Classics. Pure Grip Compound
Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at their Korbach research and development department, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name Pure Grip, is ranked just behind their BlackChili compound and is being used in their performance products both on the road and MTB sectors. It provides great grip, highly durable and long lasting.
