SPEEDER BOOST BLACK vs. the standard versionThe limited black, out Oct 29, side by side with the standard version using Fujikura's official spec table

Updated: Oct 3, 2026Contains affiliate links

The difference between SPEEDER BOOST BLACK and the standard version is color and 1 g of weight. Torque, kick point, length and price are all the same in Fujikura's official table.
It goes on sale Thursday, Oct 29, 2026, in limited quantity, at ¥49,500 per shaft (incl. tax).
But there's a number I'd like you to know before you choose black or white.
The 60S equals a 40R.
Compared with Fujikura's own NX GOLD, the BOOST "60S" has the same frequency as a "40R". Choose by the letter S, and you'll get a much softer shaft than you expected.
As a gear nerd with a 72 average and a 68 best who spends most of my time studying how clubs are built, I lined up BLACK and the standard version using only the official spec tables. By the end, you'll know whether to wait for the black, buy the standard version now, or skip BOOST altogether.

Bottom line

BLACK is 1 g lighter in every model. Every other number matches the standard version

I lined up Fujikura's official table model by model. The only column that differs is weight.

Source: Fujikura official news (Oct 2, 2026) and product pages. All lengths are 46.0 inches, tip diameter 8.50 mm. Both are ¥49,500 per shaft (incl. tax; ¥45,000 before tax), assembly and grip extra. Checked Oct 3, 2026.

1 g is small.
How small? For the 50S, 54.0 g vs. 55.0 g is about 1.9% (my calculation). The weight gap between the R and S of the same BOOST 50 is also exactly 1.0 g. Think of it as no more than the difference between two flexes, and it's easy to picture.

Torque (how easily the shaft twists) runs from 8.2° on the 30 to 4.5° on the 60, getting larger as models get lighter, and that progression is exactly the same for the standard version and BLACK.

Fujikura says the design replaces the white, blue and orange parts of the standard version with black and silver. If a white shaft standing out against a black head has bothered you, this is the biggest difference.
Honestly, I prefer the black too.

A BOOST S is softer than other S shafts

What sets it apart from other shafts is where it bends. Fujikura says it deliberately lowered the bending stiffness in two places, the butt and the tip, while keeping twisting in both sections in check (the company calls this "VTC × Double Kick"). The butt flexes at the transition to store lag, then the tip kicks back toward impact and the head speeds up. Hence "two-stage acceleration."
In short, it has two places that bend.

This design shows up directly in the stiffness numbers. I lined up Fujikura's published frequencies (how many times the shaft oscillates per minute; lower is softer) against the company's NX GOLD.

Source: reference frequencies from Fujikura's official SPEEDER BOOST product page (200 g head, 45 inches (60° method), 50 g grip). Fujikura notes that values vary with assembly.

The BOOST 60S is 232 cpm, the same number as the NX GOLD 40R. The 40S and 50R are both 208 cpm, right alongside each other.

Same letter S, completely different shaft.
Pick a BOOST 50S with your usual sense of "S" and you'll end up with a quite soft shaft. An article that actually installed them in a PING G440 MAX and measured them got 226 cpm for the 60S and 219 cpm for the 50S (Minna no Golf Digest, March 2026). The same article describes the 60S as a "heavy-but-soft" shaft whose own weight creates bend in the butt section.

That's why my top pick is one weight class heavier. Even after adding weight, you're still on the soft side. A light, soft BOOST raises the worry that it bends too much and your timing won't match. Letting the weight pull the butt section suits the double-kick design more naturally.

I also wrote about the lack of a common standard for flex letters in Shaft flex: S vs. R. Even within S, weights range from 47 g to 82 g.

Choosing a model: 40S and 50R are equally soft

30R (BLACK 37.5 g). The lightest BOOST

The standard 30R also goes on sale the same day, Oct 29. Its 8.2° torque is the highest in BOOST, so it twists easily. It's for players whose current driver shaft is in the 40 g range and still feels heavy.

Great for you if you

• Your current shaft is in the 40 g range and you're often late to the ball
• Women and seniors who want to try BOOST among light shafts

Better to skip if you

• Players using 50 g or more now (it would be too light)

40R / 40S (43.5–44.5 g). If unsure, decide by weight

The 40S and 50R share the same 208 cpm frequency. If you can't decide, choose by weight alone. For a lighter swing, take the 40S; if you want extra weight to pull the butt section, the 50R.

Great for you if you

• Your current shaft is in the upper 40 g range to around 50 g

Better to skip if you

• You miss left a lot with your current shaft (at 6.9° torque, it shifts even further toward draw bias)

50S / 60S (54.0–63.0 g). These two are the top picks

The 60S has 4.5° of torque, the most twist-resistant in the series, yet its frequency matches the NX GOLD 40R. If you play a 50g-class S shaft now and want to try the BOOST, I'd start with the 60S. If it feels heavy, drop to the 50S.
Start heavy, then go lighter.

Great for you if you

• Your current shaft is in the 50 g range and your transition timing is off every time
• You slice, but you know the cause is the face arriving late at impact, not your path

Better to skip if you

• Players who hit driver 250 yards or more
• Players who hook it left with their current shaft

A shaft only fixes a slice when a lagging face is the cause

So will it fix a slice?
Fujikura says BOOST is for slicers, players with slower head speeds and players with inconsistent tempo. Its explanation is that the shaft's kickback reduces face opening and closing, giving more solid contact.

But slice curve is set by the difference between the face angle at impact and the direction the head is traveling. A shaft can only help on the side where the face doesn't fully return. An outside-in path stays no matter which shaft you switch to.
I'll be blunt about this.

This isn't a cheap purchase.
Before you pay ¥49,500, check these 2 things.

1. Check face angle and path on a launch monitor. If the range's machine shows your path coming well outside-in, it's a motion problem. If only the face is open, a shaft or loft change may help.
2. Find out your current shaft's weight. Check the sleeve or the manufacturer's spec table. If you switch to BOOST, the section above lets you narrow it down to one model from that weight.

How loft changes a slice is covered in Can loft reduce a slice?, and how to tell whether it's your motion or your gear in Lessons or new clubs: which comes first?

I hit driver 270 yards (my own measurement), and I wouldn't choose BOOST. Not because it's badly made, but because the golfer it's designed for is my opposite.

Wait for black, or buy the standard version now?

Performance is the same. Only three things decide it.

• Want it to match a black head → BLACK on Oct 29. Limited quantity, number not announced.
• Need it for a round this month → the standard version now.
• Want to try first → hit the standard version. Fujikura posts demo day info on its official site. Once you've settled on a model, you can choose black.

You don't need to buy if you already use the standard BOOST and are happy with it. No need to pay ¥49,500 for 1 g and a color.
That's money wasted.
