| Nitrogen gas filled DUAL STRUCTURE head |
DUAL STRUCTURE By creating an internal wall at the rear of the dual-structure face, the crown and sole are connected, creating a Nitrogen-loaded box. This box significantly increases the horizontal and vertical rigidity of the front of the head, thereby increasing the head's resistance to twisting on off-center hits. This keeps the face square to the swing trajectory, resulting in the same forgiveness as a high MOI head, where the ball's spin axis is less likely to tilt.
In addition, the increased rigidity of the front of the head due to the internal wall structure firmly receives the mass of the ball like a rigid trampoline frame, providing optimal deflection to the face, while the internal wall located close to the face creates high repulsion performance that instantly transfers impact energy to the ball. The DUAL STRUCTURE achieves both high ball speed and forgiveness, which are usually in a trade-off relationship.
Nitrogen gas-loaded head Nitrogen gas-loaded head By loading Nitrogen gas-loaded inside the head, the pressure inside the head is increased, and even if the bendable beta-type titanium, DAT55G, is thinned, unnecessary bending is suppressed, and the CT value is kept within the appropriate range at a high level, and durability is improved. The repulsion of Nitrogen minimizes the deceleration of the head after impact, minimizing the increase in ball speed on center hits and the decrease in ball speed on off-center hits, resulting in a head that can withstand the mass of the ball. (Proven 24% improvement in head deceleration)
Traditional head shape that is visually easy to set upThe peaks of the radii of the face bulge, the top line of the crown, and the back sole line are aligned in a straight line in the direction of the ball flight.The traditional head shape, which takes into consideration the symmetry of the face, body, and toe-heel, makes it visually easy to set up and pull straight, creating a positive cycle for your swing.
The BOX structure gives this shallow, low center of gravity, low MOI head the same forgiveness as a high MOI head, giving it a traditional look that high MOI heads don't have, and the head is highly maneuverable and easy to swing.The ease of swinging and rigidity make it less likely to bend, leading to even greater head speed.

The culmination of composite technology!
High-quality materials create a sense of speed like no other
|
| For the first time, we have used Toray Industries' cutting-edge carbon fiber "TORAYCA®" M40X, which has maximized strength and elasticity. In addition, we have used ultra-high elasticity "90t carbon", "Pyrofil®" MR70, which combines strength and flexibility, and "TORAYCA®" T110G throughout the entire length to maximize the sense of acceleration and impact. Furthermore, "RC15% prepreg" provides strong flex and rebound. These distinctive materials are flexibly bound together with "boron fiber" to create an ultra-high-speed shaft. |

Development Concept
Now, we are making the best flying shaft using the materials available on earth! Fujikura has developed this shaft to achieve the strongest distance performance, surpassing the DIAMOND Speeder, which has an excellent balance of bounce and flex.
By combining it with the high-spec carbon "M40X," which exceeds the T1100G announced by Toray in December 2018, we have achieved amazing bounce and speed. Furthermore, after extensive evaluation, we have arrived at "boron fiber" as a material that maintains the bounce and speed while also being easy to swing.
■Ultra-high performance materials are used that are currently available on the planet. ■Low torque design is inherited. ■Weight flow for each flex. ■Kick point is forward and inward for even greater bounce and grip. |

Ultra-low resin carbon sheet "RC15% prepreg"
The carbon sheet is laminated (12 layers for S flex) with an ultra-low resin content of "RC15%" which is further reduced from RC20%. By reducing the amount of resin, the ratio of carbon fiber increases, resulting in a dense shaft. This eliminates unnecessary movement and achieves a stronger return to flex. |

Toray's cutting-edge carbon fiber "TORAYCA R" M40X, which exceeds T1100G
Fujikura shafts are using "M40X", announced by Toray in December 2018, for the first time. This is the latest material developed for use in rockets and next-generation aircraft. By pursuing both fiber strength and elastic modulus, which are in a trade-off relationship, to the limit, strength has been improved by approximately 30% while maintaining the same elastic modulus as conventional carbon fibers. This creates an even better bounce and feeling. |

Ultra-high elastic carbon fiber "90t carbon"
By layering the world's hardest material, 90t carbon, over the full length, we have achieved maximum acceleration and strength after impact to increase the initial velocity of the ball. |
|
MR70 (Mitsubishi Chemical) + T1100G (Toray)
The tough Mitsubishi Chemical MR70 is laminated into the full-length straight layer, while the T1100G used in the SPEEDER series is laminated into the tip bias layer. The combination of these two materials achieves both toughness and flexibility. |

Boron fiber: a metal fiber with high strength, high rigidity and high elasticity
Boron fiber, which is used in fighter jet tails and racing cars and has excellent strength, rigidity, and elasticity, flexibly combines the latest carbon materials with their distinctive characteristics. This creates a super-high-speed shaft that combines peak characteristics with repeatability and stability. |
