Diamana Shaft Chart: Every Model by Launch, Spin & Weight

The quick answer: Every Diamana descends from one of three original "boards." The Blue Board lineage is mid launch / mid spin and smooth — today that's GT, TB, BB and the S-series. The White Board lineage is low launch / low spin and stout — today PD, DF, WB and the D-series. The Red Board lineage is the high launcher — RB, RF and the R-series. Mitsubishi changes the two-letter model name every generation, but the color heritage tells you the flight. The full chart is below.

Diamana is the shaft that built Mitsubishi's tour reputation before Tensei existed: the original Blue Board 73 and White Board 63 were the most-played driver shafts on tour in the late 2000s, and Diamana has stayed in the top handful ever since. It's also the family with the most confusing naming — a dozen two-letter codes across six generations, plus "Limited," "+", and "for Titleist" stock versions. This chart sorts every Diamana series by launch, torque and weight, and maps each one back to the board it came from.

Weights and torque below come from the same shaft database that powers our club grader, so they match what the app uses when it scores a Diamana in your bag.

Diamana Shaft Chart: Every Series

Flexes run R, SR (between regular and stiff), S, X and TX in the current GT, PD and TB series, with A (senior) and L (ladies) in the lightweight made-for versions. The weight number on a Diamana is the class, not the exact gram figure; a "60" is typically 62–68g depending on flex.

How to Read a Diamana Name

A modern Diamana reads like Diamana GT 60 S: series, weight class, flex. The series letters change every generation, so the useful skill is mapping them to the three lineages:

Blue lineage (mid launch, smooth): Blue Board → Kai'li → S+ → BF → TB → GT. White lineage (low launch, low spin): White Board → 'ahina → D+ → DF → PD → WB. Red lineage (high launch): Red Board → 'ilima → R+ → RF → RB. ZF sits between blue and white — mid launch with low spin — and "Limited" or "Ltd." marks a stock made-for version.

Flex letters follow the standard scheme, and Diamana adds SR between R and S in most current series. Here are the typical driver speed bands, with the white lineage shifted up because of its stiffer tips:

These follow our brand-neutral swing speed shaft flex chart. The blue lineage plays true to its letter; the white lineage plays about a half-flex firm. SR is genuinely useful here — a lot of 90–97 mph players who feel Diamana S is too much and R is too little are SR players, not borderline cases.

Practical shortcut: if a Diamana is already in your bag, add it to your bag in the app exactly as printed, including "Limited" or "+" if it says so. The app grades your set's flex and weight consistency by playing spec, not by label.

Series by Series

Diamana GT (blue lineage — mid launch, mid-low spin)

The current blue-line flagship and the one you'll see most on tour today. GT keeps the smooth, easy-loading Diamana handle feel the Blue Board was famous for, but with a firmer tip than TB for lower spin and a more stable strike. Weights 40 through 80 (46–87g), flexes R, SR, S, X, TX. If you liked the old Blue Board or Kai'li and want the modern version, this is it.

Diamana TB and BB (blue lineage — the versatile mids)

TB is the mid-launch, mid-spin all-rounder — a little more active in the tip than GT, a little easier to launch. BB is the softer-feeling blue from the previous generation, with the widest speed range in the family: it runs down to a 40-weight R. Both fit the broadest slice of golfers: 85–105 mph swings without a dramatic launch or spin problem. Between them, TB for the stronger player and BB for the smoother one.

Diamana PD (white lineage — low launch, low spin)

The current low-spin flagship. PD stands for the white-line profile at its most modern: stiff tip, low kick, the lowest torque in the family (down to 2.3°), and a slightly more forgiving handle than the old White Board so it doesn't feel like a board. Weights 40–80 (45–86g), flexes R through TX — though the R exists mostly on paper; this is an S/X shaft for 100+ mph swings that spin the ball.

Diamana DF and WB (white lineage — the stout ones)

DF is the previous white flagship and still widely played: low launch, low spin, stiff tip, torque 2.2–4.3°. WB is a modern re-issue of the original White Board character — arguably the stoutest current Diamana, with a high kick point and firm feel throughout. Both are for fast, aggressive swings that need the shaft to resist. Under about 100 mph they take away launch faster than they take away spin.

Diamana ZF (the bridge — mid launch, low spin)

ZF sits between the blue and white lineages: it launches mid like a TB but spins lower like a DF, through a stiffer tip on a smoother middle. For a lot of good players it's the "I want Blue Board feel with White Board numbers" answer. Weights 50–80 (55–86g), flexes R, S, X, TX. Torque 2.6–4.7°.

Diamana RB, RF, M+ and Ltd Red (red lineage — high launch)

The high launchers. RB is the current red — mid-high to high launch with a soft, active tip, in 50 and 60 weights (53–66g), flexes R, S, X. RF was the previous generation. M+ and the Ltd Red are the lightweight made-for versions (43–62g, A/L/R/S) built for slower speeds that need carry. The red line is chronically under-fit: many 80–95 mph players hitting low, short drives with a blue-line Diamana would carry it farther with an RB.

Diamana D+, S+, R+ and the "Limited" series (third generation and stock versions)

The "+" series was Mitsubishi's third Diamana generation — D+ (white lineage, mid-low launch and low spin), S+ (blue, mid launch), R+ (red, high launch) — and they're still everywhere in used drivers and older tour builds. The D Limited and S Limited are the tour-issue versions with tighter tolerances. The plain "Ltd." or "Limited" Blue / White / Red are the made-for stock shafts that shipped in Titleist, Callaway and other OEM drivers: real Diamanas, but softer and higher-torque than the aftermarket "+" versions of the same color. Same rule as every stock shaft — use color as a guide, not a spec.

"Limited" and "for Titleist" Diamanas: Stock Versions Explained

Diamana has been a stock option in Titleist drivers for most of two decades, and Mitsubishi builds specific made-for versions for that program — you'll see Diamana Kai'li 75 for Titleist, Diamana 'ahina 82 for Titleist, and the Ltd Blue / White / Red in older stock builds. These are genuine Diamanas with the correct lineage profile, but they're tuned softer and to a higher torque than the aftermarket version with the same name.

The practical rule is the same as with Ventus and Tensei: if you were fit on a launch monitor into an aftermarket Diamana, buy that exact shaft. If you're evaluating what came in your driver, use the color lineage as a rough guide to flight and expect it to play roughly a half-flex softer than the chart above.

Picking Your Diamana: The Two-Question Shortcut

Question 1 — what's your miss? High, spinny drives that lose distance → white lineage (PD, DF, WB). Low shots that won't carry → red lineage (RB). Neither extreme → blue lineage (GT, TB, BB). Want mid launch but less spin → ZF.

Question 2 — what's your speed? Use the flex table above and don't skip SR — it's the right answer for a lot of 90–97 mph swings. Weight follows speed and tempo: 40/50 for smooth or slower swings, 60 is the standard driver weight for most 90–105 mph players, 70 for strong swings and fairway woods, 80 for tour speeds.

Frequently asked questions

What is the difference between Diamana blue, white and red?

They're the three original launch profiles, each carried forward through every generation under new names. Blue lineage (GT, TB, BB, S+) is mid launch and smooth. White lineage (PD, DF, WB, D+) is low launch and low spin with a stiff tip. Red lineage (RB, RF, R+, M+) is the high launcher with an active tip.

What do the letters on a Diamana shaft mean (GT, PD, TB, DF)?

They're series names that change each generation. GT and TB are current blue-lineage (mid launch) models; PD and DF are white-lineage (low launch, low spin); RB is red-lineage (high launch); ZF bridges blue and white. The number after the letters is the weight class in tens of grams, and the flex letter follows.

What does SR mean on a Diamana?

SR is a flex between Regular and Stiff — Mitsubishi offers it in most current Diamana series. It typically fits about 88–97 mph of driver speed in the blue lineage. If Diamana S feels too much and R feels too soft, you're probably an SR.

What swing speed is a Diamana GT 60 S for?

About 95–104 mph of driver speed. A GT 60 SR fits roughly 88–97 mph, a GT 60 X about 105–114 mph. White-lineage shafts like PD and DF want a few more mph at the same letter because of their stiffer tips.

Is the Diamana in my Titleist driver the same as the aftermarket one?

No. The "for Titleist" and "Limited" Diamanas are made-for stock versions — genuine Mitsubishi shafts with the correct lineage profile, but tuned softer and to a higher torque than the aftermarket version of the same name. Expect a stock Diamana to play roughly a half-flex softer than the chart.

Which Diamana launches the highest?

The red lineage — Diamana RB in the current line, RF and R+ in older generations, and the lightweight M+ and Ltd Red for slower speeds. Within any series, the lighter weight in the softer flex launches higher.
