Carbon monocoque for maximum forgiveness and distance. High moment of inertia design for maximum forgiveness. [B3MAX DRIVER Unique Design] ■ Bridgestone's proprietary "biting face" and "carbon monocoque body" technologies deliver unwavering, straight flight. ■ High MOI (moment of inertia) design with up to 40g of high-performance weighting provides forgiveness on off-center hits. ■ Slipless bite milling optimizes spin. (1) Carbon monocoque body. Bridgestone's unique monocoque structure has evolved even further. By generating excess weight and optimally positioning up to 40g of weight, it improves forgiveness. (2) Body rigidity control. Slits in the face and body control rigidity for a wide repulsion range and high launch. (3) Three heads to choose from. A lineup of three highly functional head designs with different performance levels tailored to golfers' needs: the "MAX" with its 40g of excess weight, which resists wobble, and the "MAX D" with its grip. [B3MAX 9.5°] High MOI design + slightly low spin. The 9.5° club features a slightly forward-shifted center of gravity for a low-spin design. [B3MAX 10.5°] For a gentle, steady flight. The largest MOI in the B series. The 10.5° club offers forgiveness and stability. [B3MAX D 10.5°] A strong ally for slicers. The MAX D club features a moderate center of gravity distance and maximized angle. ■ New Face Technology. (1) "SLIPLESS BITE MILLING." This new face technology, born from Bridgestone's unique contact science, enhances "bite" at impact and "reduced face slippage," firmly gripping the ball, reducing spin and improving ball flight. ● A new design that increases milling density by laser cross-hatching the face surface for improved bite. Cross-hatching: A method of closely interlocking fine parallel lines to create a mesh-like pattern. ●The effect of face milling. The effect obtained varies depending on the loft of the club. When the loft is flat, only the force that generates spin is applied, but when the loft is steep, such as with Driver, both the force that tries to generate spin and the force that tries to suppress spin are applied, resulting in the effect of reducing spin. (2) SP-COR (Suspension Core) Increased repulsion performance in the toe and heel improves tolerance and reduces distance loss.
