HAMMER THROW Driver shaft$500 USD - shipping ($90 Int'l FedEx priority 4~7 business days) HAMMER THROW shaft showcases our amazing FreeFlex Technology (FFT), in which the shaft weighs a "normal" 62g, but the flex is incredible whippy at 140cpm. No other shaft in the world is this flexible. BUT the torque is below 3.5, nearly as stiff as the S-flex of conventional shafts. Our ground-breaking FreeFlex Technology allows us to adjust the flex and torque to these extreme ends to deliver formidable club speed and power even when swung lightly, addeded with low torque for accuracy. Hammer Throw shaft's unique bend profile is recommended for swinger-type golfer with a smooth tempo and transition for swing speeds between 70~110mph. The Hammer Throw shaft is manufactured at 46" with a factory design load of 62g weight, 3.5 torque and incredibly flexible at 140cpm. Designed to maximize power and club head speed at slower swing speeds, but capable of handling higher speeds if takeaway is slow with smooth transition. The Hammer Throw will feel extremely soft and flexible at waggle like a training aid, and can help to smooth out swing tempo. We recommend visiting an expert club fitter to set up the shaft for YOUR best performance. Give it a try at various swing weights to fit your swing speed (between D2-D4 for speeds of 65-100mph. The faster the swing, the lighter the swing weight can be below D0 as needed). Adapters available at $20 ea (compatible with Callaway, TM, PING, Titleist, Cobra, PXG) ABOUT FREEFLEX TECHNOLOGY A common notion in golf is that there is a trade-off between accuracy and speed: A firm shaft improves directionality but at the expense of distance, while a flexible shaft increases distance at the expense of accuracy.Thus, golfers had to choose between a stiff heavier shaft with higher a cpm and low torque for accuracy, or a lighter flexible shaft with a low cpm and high torque for more distance. But why can’t we have both? Well, now you can. Our ground-breaking FREEFLEX TECHNOLOGY allows us to control the shaft weight, flex (cpm), and torque in any desired combination to effectively balance the trade-off between accuracy and speed needed for distance. By controlling the three variables, we at SJ Golf Lab have created the ultimate performance shafts in the FF Special-series that combine the characteristics of a flexible shaft for ease of swing and faster club speed, with those of a firmer shaft at impact to improve accuracy with less dispersion.
