The All-rounder. X-King pronounced ‘Cross King' designed for XC and trail use with speed as the main priority. Developed in conjunction with the Topeak-Ergon professional MTB team who have now already recorded many race wins on what they call the ‘perfect race day tyre’. The cleverly designed tread pattern provides ample traction yet almost the rolling sensation of a much slicker tyre, giving you a seriously fast tyre option. No matter what the event or weather conditions, combining the X-King with Mountain King II and Race Kingwill provide a winning combination. PureGrip is ranked just below the premium BlackChili compound. It provides great grip as well as durability.
