HAMMER THROW Driver ShaftPrice: $500 USDInternational Shipping: $90 (FedEx Priority, 4–7 Business Days) Specs: 62 g, 140 cpm, 3.5 torque Raw Length: 46" uncut Tip Diameter: 0.335 taper Adapters Available: Callaway, TaylorMade, PING, Titleist, Cobra, PXG (+$20 each) The World's Most Flexible Performance Driver ShaftThe HAMMER THROW represents one of the most radical applications of FreeFlex Technology (FFT) ever developed. At a conventional shaft weight of 62g, the Hammer Throw features an astonishing 140 CPM, making it one of the most flexible performance driver shafts available. Yet despite its extraordinary flex profile, torque remains remarkably low at 3.5°, delivering directional stability comparable to many conventional stiff-flex shafts. This unique combination of ultra-low CPM with controlled torque is only possible through FFT, which independently engineers flex and torque rather than forcing golfers to accept the compromises of traditional shaft construction. The result is a shaft that stores exceptional energy during the swing while maintaining impressive clubface stability through impact. Who Is It Designed For?The Hammer Throw is designed primarily for golfers with a smooth tempo and gradual transition, particularly those who generate speed through rhythm rather than force. Recommended for swing speeds between 70–110 mph, it helps players maximize shaft loading naturally to increase clubhead speed and improve energy transfer. Golfers with slower swing speeds will experience effortless launch and increased distance, while many faster swingers with a smooth transition can also benefit from its unique loading characteristics. Performance Characteristics Exceptional shaft loading with minimal effort Promotes increased clubhead speed through efficient energy release Ultra-soft feel encourages smoother tempo and sequencing Low torque helps maintain directional consistency Designed to reward rhythmic, fluid swing mechanics During the waggle, the Hammer Throw feels exceptionally soft—almost like a swing training aid—providing immediate feedback that naturally encourages a smoother takeaway and transition. Fitting RecommendationLike every FreeFlex shaft, the Hammer Throw performs best when professionally fit.Because of its unique profile, swing weight can significantly influence performance. Recommended starting points: 65–100 mph: D2–D4 100+ mph: Lighter swing weights (D0 or below may be preferred depending on the golfer) A qualified club fitter can optimize head weight, playing length, and swing weight to maximize performance for your individual swing. Specifications Length 46" Weight 62g Flex Frequency 140 CPM Torque 3.5° Recommended Swing Speed 70–110 mph Player Type Smooth tempo / Swinger 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.
