Tires
The tyres are designed for mountain biking. The lateral lugs provide good grip on turns. The tyres use SkinWall technology. This process reduces their weight and makes them more flexible, which increases 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.
