The celebration of twenty years of Diamana continues, with Mitsubishi Golf unveiling the second part to the all-new version of the legendary lineup. It makes sense that the brand came with the WB (White Board) first, as it has long been the first design people think of when they hear “Diamana”, but as soon as it was released, the clamoring for the BB was immediate. Previously, we were able to give a full review on the Diamana WB (here: Mitsubishi Diamana WB Shaft Review – The Hackers Paradise) and now, on the day the 2024 Diamana BB is officially released, we are not only bringing you all the details, but also one of the first full reviews in all of golf.

Quick Take – 2024 Diamana BB
The Blue Board is back. As with the WB, when it comes to the BB, Mitsubishi has managed to up the ante by taking the same legendary profile that is known and loved, but amplify it with new materials and technologies. On the course, the BB is exactly what you would expect, fluid without being loose, and lives up to the mid-mid profile designation.
2024 Mitsubishi Diamana BB – Design
For 20 years now, Diamana has been the crown jewel of Mitsubishi Golf. When it comes to performance and feel, the company truly believes they are at the top of the game with this family of shafts. However, they also want it known that although the designations of these new Diamana shafts is the same historically with WB being “low-low” and this BB being “mid-mid”, this is not just a rehashed release. No, this is taking the DNA of the “boards” and modernizing it.

In this 6th generation BB, new meets classic, beginning with the matte black finish and retro cosmetics, including the illustrious “flower band” below the handle. Just as we said about the WB, the BB is one of the best looking driver shafts we have seen in some time, it’s clean but also flashes in the right ways. Plus, there is something cool about being able to immediately tell visually what someone is playing, and the flower band with classic blue backed Diamana logo absolutely brings that recognition to this release.

The new Diamana BB profile is classified by Mitsubishi as Medium+ under the hands and mid-section, then Medium in the tip section, and is also being offered in the traditional 53/63/73/83 weight categories. This leans into the smooth feel which the BB is historically known for. However, according to the company, that has been taken up a notch via improved materials and processes.
| SHAFT | FLEX | WEIGHT | TORQUE | KICK |
| Diamana BB 43 | R2 | 44 | 5.1 | MID |
| Diamana BB 43 | R | 45 | 5.1 | MID |
| Diamana BB 43 | SR | 47 | 5.1 | MID |
| Diamana BB 43 | S | 48 | 5.1 | MID |
| Diamana BB 43 | X | 49 | 5.1 | MID |
| Diamana BB 53 | R | 50 | 4.9 | MID |
| Diamana BB 53 | SR | 52 | 4.9 | MID |
| Diamana BB 53 | S | 54 | 4.9 | MID |
| Diamana BB 53 | X | 55 | 4.9 | MID |
| Diamana BB 53 | TX | 56 | 4.9 | MID |
| Diamana BB 63 | R | 60 | 3.2 | MID |
| Diamana BB 63 | SR | 61 | 3.2 | MID |
| Diamana BB 63 | S | 61 | 3.2 | MID |
| Diamana BB 63 | X | 62 | 3.2 | MID |
| Diamana BB 63 | TX | 62 | 3.1 | MID |
| Diamana BB 73 | S | 70 | 2.9 | MID |
| Diamana BB 73 | X | 71 | 2.9 | MID |
| Diamana BB 73 | TX | 72 | 2.9 | MID |
| Diamana BB 83 | S | 80 | 2.8 | MID |
| Diamana BB 83 | X | 81 | 2.8 | MID |
| Diamana BB 83 | TX | 81 | 2.8 | MID |
As with the WB, the BB is implementing “Xlink Tech” which is another Mitsubishi developed resin system. By reducing the amount of resin necessary in creating a composite shaft, they are able to use more carbon fiber volume. That increase not only means more feel, but also more strength and durability. Combined with that, the 6th generation Diamana’s also use high-modulus 46-ton angle plies to lower torque and increase stability as well as super high-modulus 80-ton Dialead Pitch Fiber in the butt section of the shaft for better energy transfer.
In the end, Mitsubishi believes they have created a better Blue Board which is smoother than ever, but with a new level of stability and downrange consistency.
2024 Mitsubishi Diamana BB – Performance
As mentioned, not only are we bringing all the details for the BB release up above, but THP was also able to get the new design in hand and put it to the test. More than that, four of our community members were able to as well, and they will be bringing their long-term feedback to the THP forum, so be sure to keep an eye out for that.

This review was done with the Diamana BB in 73X paired with the Callaway Paradym Ai Smoke Triple Diamond head at 9.0 standard. Having also done our previous review on the WB, there were many curiosities entering into this, specifically because once upon a time the Blue Board was a go-to for me, specifically in a lower spinning driver head like what this testing was done in.

The standout aspect immediately here was that classic BB ‘feel’, which personally I prefer to use the term flow. Throughout each swing, there is a flow present which absolutely differentiates it from the WB. Interestingly when it comes to that comparison, however, is that this 6th Generation WB is strikingly smooth, more than any previous iteration I had swung. Well, the same can be said about the new BB. Regardless of how I went at the ball, that feel/flow was present, be it high-speed, mid, or even user error driven swings.

While feel is great, it is the flight, spin, and dispersion characteristics which everyone cares about the most. Both on the course as well as on the launch monitor, the 73X BB proved to be every bit the mid-launch shaft it claims for this reviewer. When it comes to the data you will see below (which comes from a set of ten swings with the two biggest misses thrown out), it checks the boxes. Now, some may see the launch and spin as a bit on the lower side to be called mid-mid, but keep in mind this was with a 73 version of the shaft.
| Diamana BB 73X in Paradym Ai Smoke TD 9.0 STD | |
| BALL SPEED | 162 |
| LAUNCH ANGLE | 14.1 |
| SPIN | 2590 |
| PEAK HEIGHT | 33 |
| CARRY | 274 |
| TOTAL | 300 |
| OFFLINE | 9Y R |
What is the conclusion? This is going to be a very popular, and very versatile, shaft for Mitsubishi. While this review was done in a driver, it is obvious that there are ample fairway wood applications possible as well. In fact, when you combine the BB with the WB, the fitting possibilities are significant. Smooth, reactive, accurate, and fantastic looking, the 6th version of the Blue Board lives up to the hype.
The Details – 2024 Diamana BB
Mitsubishi is releasing the new Diamana Blue Board worldwide beginning today through fitting centers and custom order options across the world. While nostalgia alone does wonders, it is only when a brand takes that and molds it with modern performance that you strike onto something more, and that certainly appears to be just what is happening with Diamana right now. The price point for the BB will be set at $400.00.
For more information, head over to their website at www.mitsubishigolf.com.




The original Blue Board was one of my first after market shafts I ever bought when it was brand new.
Excited for the next generation and looking forward to giving it a try.
Tipped it (with adapter), trimmed it and gripped it this weekend and ready for it’s first action this afternoon.

Great review James! It is certainly a stunning shaft that performs well in your hands. Looking forward to getting mine out to see how it works in a lighter and softer version in the hands out someone with a 20+ mph less swing speed.
So good looking! And such an iconic shaft!
Great writeup, sounds like one I would get along with. The 43X kind of caught my eye as something I’d be curious to try
It’s July 1st and I’m excited to see the updated version of the blueboard. This should a good number of players. Great design on this one.
What a great-looking and iconic shaft. I’m so happy it is coming back.

Man I loved the blue board. Sounds like with the tech upgrades this is going to be a really great shaft. Slightly disappointed that the shaft itself isn’t blue though.
I actually think the blue was more iconic than the white.

Yep. It’s an exciting time for Mitsubishi imo.
And thank you for taking the time to read it my guy!
The BB was and has been more present visually to most, being a standard offering in many different clubs over 20 years, but the WB set the standard for a low/low shaft when it released, proving such a profile could exist and not be void of all feel.
Diamana, as a whole, is iconic.

1000% agree on the last statement. The blue was basically in every fairway wood on tour for a few years. lol.
I also @agree with [USER=5944]@jdtox[/USER] that I wis the shaft was blue.. and the white silver..
But that’s been done, for ages. To celebrate 20 years AND to differentiate, something needed to actually be different visually.
Plus, the matte lets the logo and return of the flower band pop in ways the color and ion color finishes didn’t imo.

I love the matte look, love the flower band. I just think something a little better could have been done other than change the background oval. That being said its all cosmetics and personal preference. None of that matters when it comes to performace.
Sure it is, but it’s worth discussing.
They HAD to differentiate for the 6th gen and 20th anniversary, and all the other generations have been either the color of the shaft profile, or silver, so do they release a new shaft that people visually confuse for the older versions? Or do something different? The logo and flower band being back HAS To be there as it’s the nod to 20, so where would they go?
Plus, a nice touch is it’s a look that will look good in ANY of these crazy looking driver heads we have out now, even the limited edition ones. I respect that.

I don’t hate it, I like the matte black better than the silver of the past, like I said personal preference. I guess if its meant to be a throwback it makes more sense but its not like they haven’t had the blue oval before.

It is meant to be a throwback, and that’s where the flower band coming back combined with the logo makes it happen.
I think many here underestimate the nostalgia that flower band has. This lets it pop.

yes, this is all I was saying. It looks great. I just think they could have left it blue and changed it in a way to be updated.
I’ve pretty much always been a blue profile guy and the weight/flex options would be really interesting to test out properly to see which would fit best.
Great write-up and it’s awesome that THPers get to put these into play!

How though? A blue board that looks like the past 4/5 blue boards isn’t exactly good for the new version marketing wise. Golfers not crazy on a forum like us, so 90% out there, can’t differentiate and would simply go with the cheaper one as opposed to the higher performance and more technologically advanced one.

Fantastic write up @Jman! These looks fantastic and personally I love the matte look. Can’t want to give one a swing.
I had a hunch this was the mystery shaft even if I was a little hopeful it was going to be both BB and RB.

Can’t have a WB release without the BB! It’s exciting that we were/are the first non Tour people in the world to get these in hand to work with.
As with the WB, the Blue Board looks great in hand. I never had the chance to play a BB in the past so this will be my first experience with it. The early results from the WB have me very excited to give this a go. I’ve got the same 53 X ready to get in play.
I love the matte black with the blue board and white flowers. It’s just enough to make the shaft pop when looking at it. I have it I. The Darkspeed X so it does go perfectly with the pops of blue on the driver.

Can you that THP and the Tour are the only ones playing this shaft?! ?
There are lots of options to keep it blue and update it. It is fine as is and I am being extremely picky here. At the end of the day it is the smallest of details and complaints. Really not a complaint, just a simple preference that is easily overcome. I just liked the blue. But that it is not, is really not a big deal at all.
I want a 60 gram white for a driver and a 83 gram blue to install into my 19 degree UW…

That would be fun to see you hit
Oh man, I see some lighter weight shafts being tested. After trying some, really looking forward to the 60g and below weight class performance.
I need to get one of these in hand
This shaft is B-E-A-U-T-I-F-U-L…Didn’t get any range time and hit it off of 5 tee’s yesterday. So not a lot of data or thoughts yet. It feels great. The feels balanced. The feedback on the hits felt positive, no mishits. Actually produced a DRAW on my driver. My drives typically are straight. Again, more data will be collected on Friday, Saturday and Sunday, so take all of this with a grain of salt right now. My playing partners thought it was GORGEOUS. I didn’t let them hit it though 😉 ROFL. LOGO UP![ATTACH type=”full”]9278161[/ATTACH][ATTACH type=”full”]9278162[/ATTACH]

The numbers posted: was this a stock ball flight?
I ask because at 2500 spin if you are fading the ball (only 9 yards dispersion is pretty damn good) the spin may be slightly higher.
What length do you have this built?

Yes, my stock flight is a fade. I’m not a high spin golfer, I’m at a good speed and low spin by nature/delivery.

Thats why I was asking… I can creep into the 3k range on well struck balls. Sounds like a solid combo.
Great write up, sounds like it’s right in my wheelhouse. I’m pretty happy with the Tensei Blue and I always struggle with the price of after market shafts though. Regardless, seems like it will be a great option for many.
Feel like one of these might make it’s way into my ST-G 3 wood rather quickly
