The special construction achieves a smooth effect in the shovel with slightly open ski tips. As a result the ski can be turned more easily, more quickly and with less effort. In addition to this it gives you perfect gliding properties in soft conditions in unprepared terrain. The construction is characterised by two numbers. In the case of the 5/10 Nordic Rocker construction, for example, the 5 refers to the height difference in millimetres of the ski tip with/without pressure on it. The 10 shows how many centimetres the contact point of the ski moves back when pressure is placed on it compared to when there is no pressure on it.
With this climbing system for the steel edge models the kick action improves considerably in all terrain. As a result the ski is convincing especially away from the prepared tracks and also in difficult terrain conditions. Offtrack Crown was developed exclusively by Fischer.
