The 4-cross chassis is made of aluminum and is made in one piece, so it is absolutely straight. A special feature of the chassis is its binding system, which allows you to use any Powerslide or cross-country shoes. This means that it can be used at any time of the year. Despite their size (180 x 50mm), the tires maintain acceptable weight, saving you energy. The 4-Cross frame is ideal for year-round skating enthusiasts.
