Long, forgiving and easy to hit – Callaway officials say those are the primary performance attributes of the new Big Bertha B21 driver. Designed to be a high-launch, low-spin product with “ultra-low” forward center of gravity, it also is endowed with internal draw-bias weighting, to take the big miss out of a player’s game and help him or her hit tee shots a long way and into more fairways.
Distance, those technicians say, is enhanced by the use of Callaway’s artificial-intelligence-designed Flash Face SS21 technology, which is made to promote faster ball speeds across a more expansive area of the clubface. Speed also is boosted through the employment of Jailbreak technology, which uses two internal bars to connect the sole and crown just behind the clubface and increase the energy transfer. That crown is composed of carbon, which allows technicians to redistribute weight for an increased moment of inertia and greater forgiveness.
Available in lofts of 9, 10.5 and 12.5 degrees, the Big Bertha B21 driver also features a Callaway-designed RCH shaft, with an Active Tip Flag section for easy launch. As for the stock grip, it is Tour Velvet Soft from Golf Pride.
