The Rossignol Sender 104 Ti Open Plus ski is like the little brother to the Sender 106 Ti Plus Open ski, with just a slightly slimmer waist and some different build qualities. With 104- millimeters underfoot, these skis still have plenty of width to float through powder and soft snow conditions, but its performance does not stop there. Built with a Poplar wood core, the skis are stable and smooth. When Rossignol adds a rigid titanal beam underfoot bolster the strength and stamina of the skis. Additionally, Rossi adds 2 strips of their Line Control Technology that's been used in a variety of their skis over the past few years. This one for the Sender Ti is made of ABS plastic, the same material found in your sidewalls, and adds a more playful touch to the ski while still keeping it substantial. By adding this vertical strip of ABS in the central portion of the ski, the fore/aft flex is bolstered and it does a great job in preventing the ski from counter-flexing, which also gives it great carving performance on hard snow. With all of this technology, you get a powerful freeride ski that is ready to ski fast and hard and take no prisoners. If you are the kind of skier who likes to go big, ride fast and looks for a powerful and damp ski that can perform at its best when pushed hard, then the Rossignol Sender 104 Ti Plus Open Skis will deliver for you.,
