With the Michelin WildRun'R and the foldable Michelin WildRun'R Advanced Light, the world's largest tire manufacturer is launching two pure slicks for mountain bikes. The background: Many mountain bikers rely on road conditioning training during the winter months. In addition to its excellent grip level, the slick offers an unprecedented level of noise comfort on asphalt. With a width of only 1.10 inches, the Michelin WildRun'R Advanced Light is extremely narrow, allowing for particularly agile handling.
