    The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres use SkinWall technology. This process makes it possible to reduce their weight, provide greater flexibility, therefore increasing their performance, grip and comfort. The recommended tyre pressure is displayed on the tyre sidewall (between 2 and 3.5 bar). 20-inch 1.7"-2.2" wide inner tube with Schrader valve.
