Forged Ring Construction Forged from a lightweight and high strength aluminum that is milled to an exacting shape, Forged Ring Construction unites a massive rear weight, a full carbon sole, crown and a milled back cup face. Creating a confidence-inspiring driver designed for increased stability and forgiveness. SIM Inertia Generator The asymmetric Inertia Generator is designed to provide faster club head speed through advanced geometry and aerodynamic analytics. A full lightweight carbon sole enables the redistribution of mass for a deeper CG and enhanced forgiveness. Speed Injected Twist Face Speed Injected Twist Face improves ball speed by calibrating each head to the threshold of the legal speed limit with corrective face curvature also protecting against heel and toe mis-hits. Thru-Slot Speed Pocket Our most flexible Speed Pocket™ design is engineered to maximize ball speeds and produce additional forgiveness on low face strikes. Split Mass Weighting Featuring a TPS weight on the sole of the club and 16 grams of steel at the rear, this design element promotes enhanced forgiveness and spin properties while allowing for precise target swing weights during custom assembly.
