Normally with a Classic waxable ski one adjusts the length and position of the wax zone to suit the conditions. But Nanogrip is a fixed length wax zone, Atomic Skintec Sport is a fixed size Skintec, the Atomic Redster has a choice of wide or narrow Skintec modules. So one needs to adjust the balance point since one can’t adjust the wax zone.
NIS on classic skis: “Moving the binding backward on a classic ski will increase the glide, because you will sit slightly higher on the flex curve of the ski,”Austrem explains. NIS on skate skis: On skate skis, the NIS binding principle is the same, but because of the ski and flex construction, the effects of moving the binding forward/backward is slightly different. If you move the binding back, the skis will feel like they accelerate faster, they ski easier from standstill to race pace. This might be a benefit on hillier courses with lots of transitions. Moving the binding forward is the opposite. It might feel harder to get the skis “up to speed,” but you’ll reach a higher max speed.“You can think of the NIS binding steps as the gears on your car: Moving the binding backward is like using your lower gears, moving the binding forward is like going into overdrive,” Austrem explains. This is probably because with a skate ski you are using a V motion and pushing on the ski edge. So moving the binding backwards means there is a shorter distance of ski behind the binding and one puts more pressure under the heel and tail of the ski – like a bicycle low gear where the wheel covers less distance. This page has graphics showing the pressure distribution on both Skate and Classic Skis www.fischersports.com/en/Nordic/Service/Assembly-of-the-binding
- moving the binding forward increases pressure in the shovel area.
- moving the binding back increases pressure in the tail.
