The SIM 2 returns with increased stability and forgiveness, giving you the confidence to step up to any tee shot. A new Forged Ring Construction delivers a new dimension of distance and forgiveness. Lightweight, high strength aluminum is milled to unite a massive rear weight, a full carbon sole, crown and new milled back cup face. The SIM Inertia Generator is asymmetrically designed to provide faster club head speeds through advanced geometry and aerodynamic analysis. A lightweight carbon sole allows for redistributed mass for deeper CG with enhanced forgiveness.
