WHAT YOU NEED TO KNOW
The Mitsubishi Diamana BB (Blue Board) is the mid-launch, mid-spin profile in the current Diamana generation. Mitsubishi pairs its classic Diamana feel with 80-ton pitch fiber in the butt, 46-ton fiber in the angle plies and its Xlink Tech resin. We sell every BB weight from 43 to 83, R2 through TX. It arrives assembled with your choice of adapter and grip, ready to attach to your driver or fairway wood head.

Who It's For
Good fit if you...
- Want a mid launch and mid spin, between the WB and RB
- Like a smooth, balanced feel from handle to tip
- Want the Diamana material package and classic Blue Board look
- Want a wide weight range: 44 grams (43 R2) up to 81 grams (83 series)
Not the right fit if you...
- Need to bring launch and spin down: the Diamana WB is rated low launch, low spin
- Need more height: the Diamana RB launches a little higher
- Want a very stiff, boardy handle
How It Plays
Mitsubishi rates the BB mid launch, mid spin, with a flex profile of medium-plus butt, medium-plus mid and medium tip and a mid-high kick point. That puts it in the middle of the current Diamana line: flatter than the RB, higher than the WB.
80-ton DIALEAD pitch fiber in the butt adds stability and energy transfer. 46-ton high modulus fiber in the angle plies lowers torque and adds stability, and Mitsubishi's Xlink Tech resin increases strength and durability while raising carbon fiber volume for better feel.
The BB also brings back the original 43, 53, 63, 73 and 83 weight names.

Questions & Answers
Have a Question?
-
Is the Diamana BB a better fit for a Fairway Wood than a Driver for a high-speed player?
The BB is known for its balanced, mid-launch profile and smooth feel, making it a versatile option that works well in either a driver or fairway wood setup.
Though it works well in both, it’s often used in fairway woods by stronger players who want a slightly easier launch compared to their driver shaft.
-
How is the kick compared to other Diamana profiles?
The BB sits right in the middle of the Diamana family for kick, more than the WB and less than the RB. But what really sets it apart is how it delivers that kick. There's no obvious loading zone or hinge point where you feel it snap; the energy just flows seamlessly from the handle to the head in one smooth motion. Compare that to the WB which has a more explosive, powerful feel through the mid section, or the RB which has a more active and pronounced tip release. The BB is the most forgiving of the three to fit and plays well across a wide range of tempos and swing speeds. If you've ever hit a TB or BF from a previous Diamana generation and loved that feel, the BB is essentially that same profile brought up to current materials.
-
What's the launch and spin profile?
Mid-launch, mid-spin. Nothing fancy going on with the ball flight, optimal trajectory and stays straight. The materials (80-ton Dialead Pitch Fiber in the butt for energy transfer, and 46-ton fiber in the angle) are doing a lot of work to keep the torque down and the energy moving through the shaft. What you'll notice is that it doesn't balloon on you the way a softer shaft can, and it doesn't feel stiff or punishing either. It just launches nicely but with a bit of authority and gets out of your way.
