MORE EXTREME AERO DESIGN An improved aero shape features a higher crown peak, and a more streamlined shape with smoother curvatures for further drag reduction and maximized speed. TOUR INSPIRED SHAPING: The refined clubhead offers an elevated appearance at address, promoting better workability and control while providing added forgiveness. NEW INTERNAL ADAPTIVE WEIGHTING SYSTEM: The re-engineered PWR-BRIDGE weight in the 9.0 driver features a slight curve, positioning the center of gravity lower and more forward. This design reduces spin and increases speed for longer drives. LARGER H.O.T. FACE INSERT: The larger forged face insert with H.O.T. face technology improves face flex, delivering more distance and higher ball speeds. BLEND OF FORGIVENESS & SPIN CONTROL: A back weight paired with a forward weight allows for fine-tuning spin and enhancing forgiveness, giving you better control over your shots.
