The Salomon Prolink Race Classic binding is a screw mounted NNN compatible binding. So, it needs to go on a ski that can accept screws. This includes: current Salomon skis, older flat (or blank) skis as well as flat (or blank) rollerskis. It has one of the best boot to ski connections according to Amy.
From Salomon: The PROLINK RACE CLASSIC binding is mounted at the optimum position to get the most out of Salomon skis. Its low ski/binding connection puts power right next to the ski for maximum transmission and feel. Compatible with Prolink®, NNN®, Turnamic® boots.
