The Rossignol 104 Ti Open Skis with bindings sits in the middle of the Sender series with a 104- millimeter waist with slightly different construction and technology than you will find in the 106 Ti. That slightly narrower waist will give you more hard snow performance and grip, while still proving plenty of float when you get that fresh dump. Construction is made with a Poplar wood core, the skis are stable and smooth. When Rossignol adds a rigid titanal beam underfoot and a carbon and fiberglass layer to really bolster the strength and stamina of the skis while keeping them playful. Additionally, Rossi adds 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 and features 2 strips of LTI, the same material found in your sidewalls. 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. The unique combination of a powerful carver and ideal floater make the 104 Ti a one ski quiver for many western skiers or an ideal soft snow ski for Eastern skiers when they receive a fresh coat of white. East or West, North or South, the Rossignol Sender 104 Ti Open Skis with bindings is sure to appease a lot of hard charging skiers.
