With the help of the HOLLOWTECH technology the ski‘s running characteristics is improved. The cutout section in the shovel leads to a reduced weight of the freely vibrating zone by almost 15 %. The resulting lower inertia moments optimize the retraction behavior of the ski. This means that after an impact the shovel returns much faster to the stable condition, enabling the ski to keep its track much more precisely. Hollowtech creates even greater weight savings on the TX touring skis. And the Dual Hollowtech on the XX Twintip skis, allows for the fastest rotation and most controllable spin.
