About Rossignol EVO 2 Ski: Hey, I’m Robert Lazaroni, the Nordic Division Manager for Rossignol based in Park City, Utah. I’m happy to show you the EVO 2. This is a 60 mm so it will perfectly fit in track, but also enough wide so you can also go in your back yard in a non-prepared track. It’s a track base, so this is the best compromise between grip and glide, and 50 mm under foot and then 50 foot, 55 in the back. The ski is coming with NIS plates, so you just slide the binding on. You can adjust the position from the top. Very easy, with the automatic binding, just step it in, and then you just use your pole to release it. Very easy, short size. You will have a lot of fun in your back yard.
