How do I know where to mount my XC bindings on the ski?

For skate skis, bindings are typically mounted at the ski's balance point (marked by the manufacturer). For classic skis, binding position is critical because it affects the kick zone—mount too far forward and you won't get grip; too far back and the ski will drag. Most skis have a recommended mounting mark. IFP/Turnamic systems allow adjustment after mounting, which is a major advantage for classic skis. When in doubt, have a professional mount your bindings.
