Mitsubishi’s Diamana shaft franchise has an iconic legacy in golf, with a reputation built on performance, feel, and tour validation. While many golfers are familiar with the “White Board,” “Blue Board,” and “Red Board” names, the latest generation has been refined with modern technology to deliver a trio of shafts perfectly suited to different players.
I was eager to put the newest Diamana WB, BB, and RB shafts through their paces to see how their distinct profiles performed in a consistent testing environment and if they still sit alongside the best driver shafts in the game.
How We Test Shafts

All of our shaft testing is conducted using the same TaylorMade Qi35 core head set to a precise 9 degrees (measured), with each shaft cut to an exact length of 45.5 inches, fitted with a Golf Pride Tour Velvet 60R grip. Furthermore, all testing shots are struck from a white castle tee to ensure consistent tee height during testing.
The data is collected and recorded using a Foresight Sports GC3 launch monitor and TaylorMade TP5x golf balls.
Controlling these potential variables allows me to draw accurate and direct comparisons and form a clear picture of each shaft’s performance and feel characteristics.
Mitsubishi Diamana Shafts: Technology

Mitsubishi has packed the latest Diamana shafts with a blend of classic design and cutting-edge materials. The core of their stability and feel comes from a super high-modulus 80-ton Dialead Pitch Fiber in the butt section, which is engineered to maximize stability and energy transfer.
To further enhance control and feel without adding weight, they incorporate high modulus 46-ton fiber in the shaft’s angle plies. The Xlink Tech Resin System is a key component, increasing the shaft’s strength and durability while boosting carbon fiber volume for a better feel.
This combination of materials allows each profile to deliver a distinct performance without sacrificing the underlying quality.
