« What ski to use on my sitski? » Just as a standing skier, the choice of the skis will depend of type of practice, the weight and the ski level of the skier. • With the Uniski all the weight is evenly distributed over one single board. For this reason it is advisable to use either top quality or competition skis that are designed to support significant mechanical constraints. This choice means that the Uniski can work effectively and will increase the lifespan of the ski compared to one of an inferior quality. Just like for an able-bodied person, this will depend on the type of ski used and also the weight and ability of the skier. Experience has shown us that it is necessary to use a ski with an identical size as one used by an able-bodied skier of the same weight and ability. For beginners or intermediate skiers, choose a pretty soft ski (looking like a racing one but not a World Cup ski). • With a Dualski, the weight is distributed on both skis. Our own experience has shown us that it is necessary to use skis that are approximately 10 cm shorter in relation to an able-bodied person of the same weight and ability. For leisure use, medium range skis are sufficient and are often more efficient than competition skis “too hard” on which a “Dualskier” could hardly put enough pressure to use their potential. In uniski and Dualski, a rigorous sharpening of the edges of the ski is indispensable, especially on hard snow. See details on the back of this sheet. Choice of bindings The binding to be used depends on the skier’s weight and ability. It is essential that the equipment never come out of the ski while skiing that is why the bindings must always be adjusted to their maximum level. • With the uniski, we recommend bindings that can be adjusted up to 18 DIN or more. Note that “Pivot” type bindings are well adapted to the uniski because they tolerate punctual overloads so we recommend them with 14DIN minimum.. With the Dualski, we recommend “standard” bindings that can be adjusted up to 14 DIN or more or “pivot” bindings that can be adjusted up to 12 DIN (or 14). - Standard binding - Pivot binding (Rossignol Axial or Look PX) Mounting of the binding onto the ski The boots fitting the skis are 325 mm in length. Mounting is usually the same as for a shoe of an identical length: the middle of the shoe must be aligned with the marker of the ski.

Sharpening the edges of the ski It’s important to have both side of the edge sharped. Base side and external side. It’s possible to make different angle of each side. For our equipment we advise to sharp like this: For Dualski: 89° on the side and 0.5°on base side For Uniski: 88° on the side and between 0,5°and 2°on base side For skier with high level of injury, we advise to sharp the base side at 1,5° or 2° to facilitate the edging and to sharp the external side at 88°.
