COBRA DARKSPEED FW Sleeve Shaft CRAZY STF Synergy Thrust Carbon Shaft 50 60 70 Made in Japan

CRAZY STF SYNERGY THRUST is a high-performance shaft specifically designed for fairway woods, embodying two concepts: "synergy," which is the fusion of multiple forces, and "thrust," which powerfully propels the ball.

Its construction caters to a wide range of golfers' needs, from a mid-low kick point model in the 50g range to a mid-kick point hard-spec model in the 70g range. The shaft's rigidity and torque balance have been meticulously adjusted to achieve both flexibility and excellent rebound. The STF50 is ideal for mid-head speed golfers seeking a smooth swing, while the STF60/70 is perfect for competitive players who prioritize impact strength and control.

All shafts are manufactured in Japan, ensuring reliable quality supported by sophisticated manufacturing techniques. They produce stable shots from the fairway while combining high launch and long distance. Golfers who struggle with their woods or often mishit shots will especially feel the sensation of the club performance assisting their swing.

This is CRAZY's latest FW-specific shaft, and you'll be amazed by its perfection once you use it.
