Madshus Skis NIS Plates Technology

NIS Plates

Das NIS (Nordic Integrated System)besteht aus einer am Ski fixierten Platte, in welche die Bindung hineingleitet. Das von Madshus patentierte NIS wurde zusammen mit Rottefella entwickelt und ermöglicht ein besonders schnelles An- und Ausziehen. Der Langläufer kann aus den verschiedensten Positionen in die Bindung gleiten, was vor allem bei wechselnden Schneebedingungen von großem Nutzen ist.
Madshus Skis Paulownia/ Carbon Hybrid Construction Technology

Paulownia/ Carbon Hybrid Construction

Paulownia/ Carbon Hybrid Construction provides an extremely lightweight torsion box ski. Paulownia– a fast-growing, farm-raised, wood core material with fantastic weight and even density - is surrounded by carbon reinforcement for optimal lightweight stiffness and torsion whether it's for fast acceleration exercise or all-day touring performance.
Madshus Skis PTex 2000 Electra Sintered Racing Base Technology

PTex 2000 Electra Sintered Racing Base

The PTex 2000 Electra Sintered Racing Base uses polyethylene pellets pressed into a hard block and cut off into thin strips. This results in a very hard base that is relatively porous and accepts glide wax well, especially after numerous applications. The objective in waxing the sintered racing base is to match the hardness of the wax used with the hardness of the snow.
