Callaway Driver Big Bertha B21

Callaway Driver Big Bertha B21

With the Big Bertha B21 series, Callaway is specifically targeting players with medium to high handicaps. The clubs have a new formula for more length and more fairway hits, even on poorly hit shots. The combination of the clubface developed with artificial intelligence, the proven Jailbreak technology and the high-strength carbon material results in more success on the golf course. Technologies: Greater distance through straighter shots To hit the ball further, you first have to hit it straighter to avoid the loss of length from the slice. Thanks to its ultra-low centre of gravity, the Big Bertha B21 driver generates high drives with little spin and also has a draw weighting in the club head to make it easier to close the club face. In combination, this results in a more consistent ball flight for more tee shots onto the fairway and longer drives. Flash Face SS21 Callaway has further developed the Flash Face clubface designed with artificial intelligence to maximise ball speed over a larger area. This results in optimum ball speeds even if you miss the centre of the clubface. Big Bertha head shape The elongated, triangular Big Bertha head shape is particularly confidence inspiring in the address position and allows strategic positioning of weight for the ultra-low centre of gravity. Jailbreak and T2C carbon crown Two Jailbreak rods behind the face connect the sole and crown, generating greater ball speed through more efficient power transfer. The ultra-lightweight T2C triaxial carbon crown saves a lot of weight, allowing Callaway to generate a higher MOI thanks to a strategic redistribution of weight in the head. The higher moment of inertia (MOI) in turn provides a more stable club head on off-centre hits, enabling straighter shots. Specifications:
