Realizes a dual bellows structure with a newly arranged "bellows crown".

Even higher initial velocity with the triple impact of face x sole x crown.

・High initial velocity design with advanced dual bellows structure

・Mid-bag shape that is easy to hold

・Expansion of high initial velocity areas above and below the face

・Two types of loft designs with a choice of launch angle

Points of interest
9.5° for those who liked the first generation BB4
For those who liked SB-01, 10.5° is recommended.
 
Compared to the previous model, the carbon crown lowers the center of gravity.
2 bellows on the crown, 4 bellows on the sole,
It has a total of 6 bellows and is named BB-6. (BB4 means bellows: Bellows has four meanings)
 
About the club president
BB4: 45.5 inches If you install the same shaft as the previous work,

SB-01: 45.75 inches (0.25 long)
BB6: 45.5 inches

*BB4 and BB6 are approximately the same size.
*If you attach the SB-01 shaft to BB6, it will be 0.25 shorter.




Comparison of BB6 & BB4 SB-01

Comparison 1: Expansion of high initial velocity area with dual bellows structure

The crown has a bellows structure to achieve high initial velocity in the upper area of ​​the face.


Comparison 2: The crown part has a bellows structure, achieving high initial velocity in the upper area of ​​the face.

By joining a lightweight carbon sheet to the bellows crown of the bridge structure, a high moment of inertia is achieved by reducing the weight in the center of the crown.


Comparison 3: Two types of loft settings to choose from

In addition to the basic loft of 10.5 degrees, by setting the basic loft of 9.5 degrees, the loft can be set from 8.5 degrees to 11.5 degrees (in 0.5 degree intervals).





Advanced dual bellows structure

The newly developed BB6, in addition to the bellows sole structure (bellows structure) that is a feature of the BB4, also incorporates a bellows structure in the center of the crown in a bridge shape, making it possible to increase the initial velocity of the ball by utilizing the flexure of the entire head. Did.

In addition, to hide the bellows structure of the crown, a lightweight carbon sheet is glued to the crown, making it possible to achieve a natural alignment.





Shape/center of gravity




Just Meet Adjuster
The neck adjustment function allows you to choose the optimal position according to the golfer's physical condition, course layout, and weather.
The neck adjustment function structure allows you to adjust the loft angle, lie angle, and face angle, so you can adjust the ball grip, launch direction, and launch height.
