Our latest Composite shaft Classic ski.  The XLK910, our slowest ski, is very close to snow-speed, making it a top choice for elite training.

XLK900 SERIES 

The composite shaft for the XLK900 Classic Series  is made with six different materials. All six materials have exceptional vibration damping properties and three of the materials provide high strength and fatigue resistance. The foundation for the XLK is a precision lightweight core that is wrapped with several layers of unidirectional fibers with tensile strength equal to carbon fibers, but with better vibration damping properties. We chose Kevlar™ for the biaxial sleeve due to its exceptional tensile strength and tenacity. The epoxy we use to bond the fibers to each other and to the core is 3X stronger than conventional epoxy. The Kevlar™ is protected from UV degradation by a 0.25mm thick polymer applied over the fibers and UV resistant epoxy. The injection molded wheel forks are made from Du Pont’s™ toughest polymer and further strengthened during the molding process with short length carbon fibers.

 

The XLK900 is available in 3 speeds.  XLK930 is fast, XLK920 is medium and XLK910 is slow.  The XLK910 are very close to snow speed. Roller ski study in Sweden. The 920 are medium slow and the 930 are medium speed. The rolling resistance in the 910 free wheels is increased using our patented ISR (internal speed reducer) that weighs only 10 grams. The wheel forks with the built in fenders use the same strong Du Pont™ composite material that we have employed on the V2-900 series for many years
