Like the RC binding, the Atomic SNS Propulse RC2 delivers an explosive kick and improved acceleration. Ideal for all serious skiers from World Cup athletes down, it gives you perfect control at high speed. It has a Carbon Race lever that opens and closes manually. While the 1-rail construction allows every last ounce of power to be transferred and converted into forward movement. The RC2 Racing Classic binding is light too (256g per pair).
