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.

Diamana BB 43 | R2 | 44 | 5.1 | MID |
Diamana BB 43 | R | 45 | 5.1 | 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.

I’ve been burned with bind buys in the past, but I am leaning towards getting one of these.

Ohio, bit too much of a drive unfortunately but greatly appreciated
When I tested [USER=68843]@Jtubb17[/USER] ’s WB 53x and the BB 53 x I found the WB to perform better in the Cobra Darkspeed X head and the BB 53 x to perform better in the Darkspeed LS head.

Any speculation why?
The X head launched more than the LS head. So the WB worked better for me in the X head. In the LS head I hit a tight high draw with BB.
I suggested the BB shaft to [USER=68843]@Jtubb17[/USER] for a fairway wood and it is working well for him in 3 wood. Which is notable because he hadn’t found a fairway wood that worked well for him until he paired the BB shaft with it.

This is true. I originally tried the BB in my driver and it spun a little too much for me because of my swing. Once I put it in the 3W, it was a match made in heaven. As [USER=63834]@Browndog[/USER] mentioned, I have never played a 3w because I couldn’t get something that launched well for me. I love having the 3W now to fit in between my D and 2H
Just read through this thread again and i am excited to give my feedback when the time comes. for the Mitsubishi event in May. From the few swings i have taken with the BB it has a really nice feel to it. I am looking forward to hitting the BB in my Max K on course.

Excited for you man! I finally got to take a few cuts but was pretty rusty from winter. Enjoyed the feel but didn’t stripe it enough to make an impulse purchase. I hope to get back to that driving range though to demo again.

I think it is going to be a great shaft for me. I went lighter with the 43 series also!
Hopefully this hasn’t been answered already…
I just had a driver fitting done. After going through all the new releases we tried some exotic shafts in my current driver head (Cobra Radspeed). The Diamana BB was incredible. Probably better numbers and feel than any other combo I tried, including the new heads.
My question is, how close would a prior gen BB be to the 2024 version? $400 for a shaft isn’t exactly a no-go, but if I can save some money…

Check eBay for a BB shaft and you’ll likely find one at about half the retail price.
Knowing I have a BB coming is exciting, I cannot wait to have this shaft in the Max K driver head and be at Hidden Creek!
I don’t know for certain since I have not played the previous version, but I woukd say it isnt close. There is so much new tech in the latest shafts that wasn’t around before.
Also, since I was in the Mitsubishi shaft experience last year, I will say that the Mitsubishi TB is as close as you will get to the BB and can likely find one much cheaper in the second-hand market. When Mark at Mitsubishi told me I woukd have the easiest transition to the BB, because it was closest to the TB, I believed him.
I had a driver shaft fitting yesterday as I wanted to see if the Diamana BB was the proper shaft for me. The fitter liked it for me as all the numbers were good and the spin was around 2600rpms. Some were getting up to around 3,000rpms and so it ended up in a close second.

Just buy it!
Just waiting to get my 53S out once my wife has healed a bit more from her surgery.
Everyday is getting a bit closer to the Mitsubishi Experience and having a BB in my driver. I am really looking forward to getting this in hand and on course.
i have really liked the BB…feels better than my Diamana TB (never thought i’d say that)…i’ll probably have to turn down the loft a degree cause i can see that it does spin up a little but the feel is perfect for me.

[/QUOTE]
In my visual comparisons between the TB and the BB, I didn’t notice a difference in height of the ball and no ballooning with either shaft. They were both neck-and-neck with distance on normally struck balls, but the BB feels a little more, fluid. Not stiff as a board, but it has a flow feel to it.
[USER=782]@ddec[/USER] saw in the DS ADAPT thread you played 9 holes with the BB…how’d it feel for you on course?

Hell yeah. I originally plugged that BB 53s into the Darkspeed last year. I thought about throwing it into the 3w, but I wouldn’t want that weight there. It’s just a nice and smooth shaft. In the Diamana line I’m usually between BB and WB…honestly the old D+ was a really good option for me too. With us being rain soaked, the swing was a little more limited, but still get that nice feel and the ball flight was actually really solid for me. I tend to hit it high but I didn’t think I was getting anything crazy in that department to keep me from giving it a little more of an extended trial.

I’m excited to try some of the other participants shafts when we get to Hidden Creek since a lot of them went BB and then I can put it up against the RB
Got to test out the season opener edition of the BB today…mine is a 73x in a fairway wood
Let me start by talking about WB…I think it’s one of the least “harsh” low/low shafts I have ever swung, its smooth beyond belief, but thats diamana as a whole. The BB feels like to me if someone swung the WB and still found it just a little too firm. It’s just softened up enough compared to the WB where it feels even smoother but fully connected throughout the swing. It makes sense why the original generations were so dominant in FW’s. Smooth to get the launch you need but still strong
This is exactly what I thought of the WB/BB when I swung them next to each other earlier this year in driver. The stiff flex BB I felt a little too much kick, but the stiff WB it was great. However I got more ball speed out of the X flex BB than the stiff WB while keeping that same dispersion – something about the BB profile just sequences up right for me in driver. It’s been that way for a while, even as my swing has gotten faster – the previous gen Blueboard was always a reliable performer for me in a lower weight stiff. I’ll be curious to see if that holds going up to a circa 60g X.
I am pumped to swing this bad boy!
