Simply, imagine ONE shaft reacting to differing swing speeds, with the kick point being low for slow swingers and high for faster swingers. This is the true meaning of FreeFlex (without flex designation) with the shaft reacting according to swing speeds to provide incredible performance.

Free Flex Technology aims to improve and enhance both distance and direction by combining the best features of stiff and flexible shafts. Infused with our ground-breaking FFT technology which allows us to control a shaft's weight, flex (CPM), and torsional strenght, all independently of each other, FreeFlex special series shafts are designed to transfer maximum energy at impact for both hard, fast swings and even light, smooth swings.

• Recommended for swing speeds between 95~120mph but capable of handling much higher speeds with smooth transition. 
• The FreeFlex FF38 and FF45 shaft are recommended for swing speeds between 80~100mph and 95~120mph, respectively, and are soft feeling in flex though both are capable of handling higher speeds than specified. 
• The FF45 special series is manufactured with a factory design load of 45g weight, 4.0 torque and 200 cpm.
• Uncut raw length at 46" inch with 0.335 tapered tip
• The FF45 (200cpm) is firmer than FF38 (170cpm), but still feels soft overall. However, the shaft will feel stiffer the faster you swing it.
