Structure kit delivered in a small suitcase. This set includes three structure rollers that cover all conditions and will help you to improve the glide in both skating and classic skiing. In cold conditions and new snow, Swix recommends using light pressure with the tool to the base. And put more pressure in warmer conditions and transformed snow. Included rollers are 0,5mm broken V structure, 1,0 and 2,0mm linear structure rollers.
