The RBZ Stage 2 driver gives you a big, confidence-building clubface in a head engineered to promote fast swing speed. That’s a killer combo for players who like to get after it with a big swing to launch the ball long. TaylorMade engineers accomplished yet another remarkable feat in metalwood mastery by increasing the size of the clubface (4100 square millimeters) while also improving the aerodynamic properties of the clubhead.
