Rossignol's BC 70 Nordic ski can handle the groomed trails at your local snowpark or breaking trail off your back porch. With tip/tail/waist dimensions of 70/60/65mm it's narrow enough to fit in groomed tracks (unless you are the first one in...then it takes a little more work) and will give you the perfect amount of float for flatland travel through deep snow in the woods. A waxless base insures they're always ready for action and metal edges will give you confidence for traversing steep slopes. The BC 70 ski works best when set up with a burly cross country binding such as Rossignol's BC Magnum or a Salomon X-Adventure rig. This pairing will lend easy glide when you're in a track and lateral stiffness when you're skiing off-camber paths. Features Sidecut: 70-60-65 Construction: Rossitop Cap / Mounting Plate(stronger for 3 pin use) / Steel Edge Core: Wood / Air which makes the skis light yet very strong AR Positrack: Thermoformed waxless design, pleasant for gliding, with excellent grip characteristics. (waxless meaning they don't need kick-wax but still needs glide wax from time-to-time)
