  • a good in particular as delay as possible transmission of compressive forces is ensured starting from the top of the sliding board body in the direction of its underside.
  • a significant advantage is also that the measures specified a core of a relatively lightweight, such as porous, material can be used within the sliding board body, which core favors a lightweight construction of Gleitbrett stresses.

  • the specified ski can also be designed as a so-called touring or Mountaineering ski. That is, the ski disclosed herein may be designed as a cross country ski 1 for well-groomed or unpaved terrain, but also as a ski for the practice of mountaineering sport.
  • Fig. 1 shows an embodiment of a generic ski, in particular a cross-country ski 1, in a conventional manner in the central longitudinal section, that is in the binding mounting portion, a defined Vorspann admir admirer - has.
