The SPEEDER BOOST shaft was created by Fujikura, bringing together all the technology cultivated in the SPEEDER series, to open up new frontiers in driving distance. Its greatest features are the fusion of VTC Technology and a double-kick design. By intentionally reducing the bending stiffness at the grip and tip sections, the shaft progressively accelerates from the top of the backswing through the downswing and into impact.
The common feeling of unreliability in the swing and unsatisfying impact that can occur with softer shafts is eliminated by VTC Technology. It optimally controls the shaft's torsion, efficiently transferring the energy from the shaft's rebound to the ball.
This allows even golfers who are not confident in their swing speed to clearly feel the flex, naturally improving their head speed and initial ball velocity. It makes timing easier, achieving stable ball flight and greater carry.
It is suitable for a wide range of golfers, from beginners to average players, and even intermediate to advanced players looking to increase their driving distance. The "two-stage acceleration" feeling, which was unattainable with previous shafts, will elevate your shots to the next level.
