New productsSPEEDER 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: Nov 3, 2026Contains affiliate links
A black Speeder Boost came out, but what's different from the regular one?The differences are the color and 1 g of weight. Torque, flex profile, length and price are all the same in Fujikura's official table. It went on sale on Oct 29, 2026 as a limited run, at JPY 49,500 (tax included). More important than color: the 60S has the same frequency as the NX GOLD 40R. Choose by the letter S and you'll get a much softer shaft than you expect. Choose by frequency and you avoid the mistake of finding out only after it arrives that it's softer than you thought, and you can pick the one that fits your swing. That also settles whether to wait for the black or buy the regular one now. As a gear nerd with a 72 average and a best of 68, who spends all day studying how clubs are made, I put the BLACK next to the regular version using the official spec table, and I also hit the regular one in a shop hitting bay, on the shop's demo head.
What I learned in the hitting bay: I hit the BOOST 50S and 60S for 10 balls each in October 2026, in a local hitting bay (mat, room temperature 22°C), on the demo heads the shop had already fitted with them. I have never swapped them into a head of my own. The 50S carried 243 yards with 2,900 rpm of spin and gave a low, strong ball, with 1 hook in 10 balls. The 60S carried 249 yards and was steadier than the 50S, but it felt heavy and my tempo got faster over the last few balls. I only touched the BLACK and the NX GOLD in a shop. I did not hit them.
The Gear Nerd's Pick
If you buy, go one weight class heavier than usual. If you play a 50g-class shaft, take the 60S. This shaft is deliberately softened in two places, the butt and the tip, and even the 60S measures 232 cpm (Fujikura's reference value), the same as the NX GOLD 40R. Heavy, yet soft. Only in this "heavy-but-soft" form does the design really come alive: the shaft's own weight bends the butt section, and the head speeds up in two stages. Pick whichever color you like. Black or white, performance is the same.

SPEEDER BOOST BLACK vs standard: bottom line
The only reason to wait for black is looks.
The standard version is available now, and the 30R (38.5g) joins it on Oct 29, while the black is limited and the quantity hasn't been announced. If you're unsure, the safe order is to settle weight and flex with the standard version first. If the black sells out, you can't get it. That's all there is to it.
If you fight a slice but swing outside-in, a shaft won't fix it. If the problem is your motion, there's something to do before paying ¥49,500 (see the section below on telling them apart). And if you hit driver 250 yards or more, you can drop BOOST from your list. Fujikura itself designed it for players with slower head speeds.
How does BLACK differ from the standard version? 1g lighter on every model, everything else the same
I lined up Fujikura's official table model by model. The only column that differs is weight.
| Model | Flex | Weight (BLACK) | Weight (standard) | Torque | Butt diameter | Kick point |
|---|---|---|---|---|---|---|
| 30 | R | 37.5g | 38.5g | 8.2° | 14.75mm | Tip/butt |
| 40 | R | 43.5g | 44.5g | 6.9° | 14.75mm | Tip/butt |
| 40 | S | 44.5g | 45.5g | 6.9° | 14.80mm | Tip/butt |
| 50 | R | 53.0g | 54.0g | 5.6° | 14.85mm | Tip/butt |
| 50 | S | 54.0g | 55.0g | 5.6° | 14.90mm | Tip/butt |
| 60 | S | 63.0g | 64.0g | 4.5° | 15.05mm | Tip/butt |
1g is small.
How small? For the 50S, 54.0g vs. 55.0g is about 1.9% (my calculation). The weight gap between the R and S of the same BOOST 50 is also exactly 1.0g. 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.
What percent is 1 g? The lighter the model, the bigger it is
The BLACK is 1 g lighter than the standard version in every model. I calculated what share of the total weight 1 g is, for each model. The lighter the model, the larger the share: about 2.7% for the 30R and about 1.6% for the 60S.
| Model | Weight (BLACK) | Weight (standard) | 1 g difference (BLACK = 100) |
|---|---|---|---|
| 30R | 37.5g | 38.5g | 2.7% |
| 40R | 43.5g | 44.5g | 2.3% |
| 40S | 44.5g | 45.5g | 2.2% |
| 50R | 53.0g | 54.0g | 1.9% |
| 50S | 54.0g | 55.0g | 1.9% |
| 60S | 63.0g | 64.0g | 1.6% |
If you pick the 60S, the 1 g difference is about 1.6%, one ninth of the 9 g gap between the BOOST 50S and 60S. Choosing by vibration frequency (cpm) and the weight of your current shaft will cost you fewer misses after you buy than agonizing over the weight difference.
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.
| Model | BOOST | NX GOLD | Gap |
|---|---|---|---|
| 40R | 194cpm | 232cpm | −38 |
| 40S | 208cpm | 252cpm | −44 |
| 50R | 208cpm | 237cpm | −29 |
| 50S | 223cpm | 257cpm | −34 |
| 60S | 232cpm | 261cpm | −29 |
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, Mar 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 47g to 82g.
Choosing a model: 40S and 50R are equally soft
30R (BLACK 37.5g). 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 40g range and still feels heavy.
Great for you if you
- Your current shaft is in the 40g range and you're often late to the ball
- Women and seniors who want to try BOOST among light shafts
40R / 40S (43.5–44.5g). 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 40g range to around 50g
50S / 60S (54.0–63.0g). 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 50g 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

What is the SPEEDER BOOST "double kick"? The BLACK is built the same way
The shaft bends in two places, near the grip and near the tip. The butt section loads at the transition and helps you hold the lag. Just before impact the tip kicks back and the head speeds through.
Fujikura pitches this design as a fit for a wide range of golfers. The BLACK has the same insides; only the color and 1 g of weight differ. You don't need to agonize over the bend profile versus the regular version.
A shaft only fixes a slice when a lagging face is the cause
So, will it fix a slice?
The BOOST is aimed at slicers, slower swingers and players with an inconsistent tempo. It's pitched as a design where the kick-back reduces face rotation and gives a more solid strike.
But what decides how much a slice curves is the gap between where the face points at impact and where the head is moving. A shaft can only help with the "face doesn't fully close" side. If that's your cause, the BOOST is the easiest fix to try.
This isn't a cheap purchase.
Before you pay ¥49,500, check these 2 things.
- 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.
- 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?
With my swing, which carries the driver 270 yards (my own measurement), a different shaft fits better. The BOOST is aimed at players who struggle to build lag at the transition. If that's you, the tip-active design does its job as intended.
Wait for SPEEDER BOOST 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.
If you're happy with the regular BOOST, the BLACK is a pick for looks. Performance is the same, so choose it when you want it to match a black head.

Update history
What I learned hitting the BOOST 50S and 60S in a hitting bay
What I hit were the regular 50S and 60S. Both were already fitted to the shop's demo heads, so I have never swapped them into a head of my own or had them fitted at a workshop. The VENTUS TR RED 6S was the shaft that came on the Callaway QUANTUM 9-degree I used from October, and I used it as it was. I only touched the BLACK and the NX GOLD.
| Shaft | When and where | How much I hit | Carry | Spin | Misses and notes |
|---|---|---|---|---|---|
| SPEEDER BOOST 50S | October 2026, hitting bay (shop demo head) | 10 balls | 243 yards | 2,900 rpm | 1 hook in 10 balls |
| SPEEDER BOOST 60S | Same hitting bay, same day | 10 balls | 249 yards | — (not copied down) | Felt heavy |
| VENTUS TR RED 6S (came on the QUANTUM) | From October 2026, public course and indoors | 4 rounds and 20 balls indoors | 251 yards | 2,600 rpm | 3 pushes to the right in 10 balls |
What I liked about the 50S was the low, strong ball. There was 1 hook in 10 balls. The 60S was steadier than the 50S. But it felt heavy, and when I hit several in a row my tempo got faster over the last few balls. I got tired, so I fixed it by taking a break between sets.
The VENTUS TR RED 6S had a flex that was easy to feel, and my fade was steady. What went badly was the push to the right, 3 of 10 balls, which I fixed by moving the ball half a ball-width to the left. I compared it with the BOOST 50S.
For the BLACK, I went alone to a nearby shop on a weekday around noon, October 29 or 30, after it went on sale, and checked the release date. It was cloudy and 17°C. I only touched it and did not hit it. It had just gone on sale, and I could not hit it. I decided to hit the regular version first and wait on the BLACK. I have not yet checked whether I can feel the 1 g of weight saved.
What I hesitated over was the difference in weight, and what decided it was to settle the weight on the regular version first. If I chose again, I would use the 50S, then wait until I can hit the BLACK.
About the writer and sources
The writer has an average score of 72, plays 150 rounds a year, has a driver head speed of 46 m/s and hits a slight fade. I read the official numbers side by side, and for the gear I used I give my own numbers too.
I separated what I hit in a hitting bay from what I only touched in the section "What I learned hitting the BOOST 50S and 60S in a hitting bay." I did the subtractions and re-sorting of the official numbers myself. Last updated: November 3, 2026.
FAQ
What's the difference between SPEEDER BOOST BLACK and the standard version?
In Fujikura's official spec table, the only differences are that every model is 1.0g lighter, and the color (black and silver). Torque, butt and tip diameters, kick point (tip/butt double kick), 46.0-inch length and price are all the same.
When does SPEEDER BOOST 30 (the standard 30R) come out, and what does it cost?
The standard SPEEDER BOOST 30 goes on sale on the same day as the BLACK: Thursday, Oct 29, 2026. It costs JPY 49,500 with tax (JPY 45,000 before tax); assembly and grip are extra. The 30R is 38.5 g, with 8.2 degrees of torque, an 8.50 mm tip, a 14.75 mm butt and a length of 46.0 in (checked on Fujikura's product page, Oct 28, 2026). The BLACK 30R is 37.5 g, so it is 1.0 g lighter at the same 30R.
When is SPEEDER BOOST BLACK released, and how much is it?
It goes on sale Thursday, Oct 29, 2026, at ¥49,500 per shaft (incl. tax; ¥45,000 before tax). It's limited quantity, and the number of shafts hasn't been announced. Assembly and grip are extra (checked on Fujikura's official site, Oct 3, 2026).
Are SPEEDER NX BLACK and SPEEDER BOOST BLACK the same shaft?
They are different shafts. NX BLACK is a mid-tip kick shaft offered in 40–70 models at ¥44,000 (tax incl.) per 1 shaft. BOOST BLACK is a double-kick shaft that flexes in 2 places, the butt and the tip, offered in 30–60 models.
Is a BOOST S the same stiffness as an S from other shafts?
It's on the soft side. In Fujikura's reference frequencies, the BOOST 50S is 223 cpm, while the company's own NX GOLD 50S is 257 cpm. The BOOST 60S (232 cpm) matches the NX GOLD 40R.
