Coupon-eligible product: COBRA DARKSPEED sleeve with Fujikura SPEEDER BOOST shaft, Speeder Boost, VTC Double Kick

The SPEEDER BOOST shaft was created by Fujikura, bringing together all the technology cultivated in the SPEEDER series, to open up new frontiers in distance. Its greatest feature is the fusion of VTC technology and a double-kick design. By intentionally reducing the bending rigidity of the grip and tip sections, the shaft progressively accelerates from the top of the backswing through the downswing and into impact.

The common issue of a soft shaft feeling unreliable during the swing or lacking power at impact is resolved by VTC technology. It optimally controls the shaft's torsion, efficiently transferring the energy from the shaft's snap-back to the ball.

This allows even golfers who are not confident in their swing speed to experience a clear flex, naturally increasing head speed and initial ball velocity. It's easier to time, leading to a stable trajectory and greater carry.

It caters to a wide range of golfers, from beginners and average players to advanced and expert golfers looking for increased distance. The "two-stage acceleration sensation" that was previously unattainable with other shafts will elevate your shots to the next level.
