Mitsubishi TENSEI Pro White 1K Shaft Review

50 Words or Less

The Mitsubishi TENSEI Pro White 1K uses premium 1K fiber to create a more consistent, stable shaft.  More active butt section with a more stable tip.  Noticeably different than the standard TENSEI White.


Equipment-obsessed golfers know that 2021 has been a year of material stories in the shaft world.  The major players are turning to aerospace and military-grade fibers to make their shafts more consistent and higher performing.

After releasing their AV RAW line of TENSEI shafts [reviews HERE], Mitsubishi one-upped themselves by bringing out the TENSEI Pro White 1K.  Utilizing a 1K fiber that’s three times thinner than Kevlar, this TENSEI is billed as the most consistent yet.


The Mitsubishi TENSEI Pro White 1K is both instantly recognizable as a TENSEI, but also clearly something different.  What stands out most is the iridescent finish on the TENSEI branding.  This takes a shaft which is largely black, white, and grey and injects it with a burst of color.  The signature “Multi Material” logo also gets this iridescent treatment.

Other changes to the TENSEI Pro White 1K are more subtle, like the “1K Carbon” logo just under the grip.  You may also notice that the base color of the shaft shifts from black at the tip to grey in the middle.  It’s a small thing that adds another layer of visual interest.


One of my biggest questions heading into this test was, “Is the TENSEI Pro White 1K going to feel any different than the standard TENSEI White?”  It took about three swings for me to realize, “Yes, this is a different beast.”

Let me start by stating the obvious: in the grand scheme, the Pro White 1K and the AV Raw White [review HERE] are very similar.  They’re tip-stiff shafts that are very smooth with a little action in the butt section.  That said, the Pro White 1K has more of everything.  When I put a strong swing on it, there’s more action in the butt.  On the other end, the tip feels even more stable.  For me – a player that needs tip stability but likes a smooth feel – this is perfect.


While the technology and material stories are interesting, we play golf to hit shots and enjoy ourselves.  What stood out most to me about the TENSEI Pro White 1K shaft is how much fun it is to hit.  From the very beginning, the drives I was hitting with the Pro White 1K were putting a smile on my face, and I kept swinging long after I’d gathered the data I needed.

That enjoyment came from the combination of feel and results.  I loved having the sensation of the shaft “working,” then looking up to see the ball launched in the optimal window.  With just enough spin to keep the ball in the air, my best drives had minimal curve and seemed to carry endlessly.

Thanks to that combination of feel and tip stability, the TENSEI Pro White 1K allowed for all manner of swings.  I could make an 80% swing and still get a consistent feel.  The super stable tip allowed for the 110% swing, too.  A shaft that can work well with both is a rare find.

The Mitsubishi TENSEI Pro White 1K is available in 50, 60, 70, and 80 grams.  Four flexes – regular, stiff, X, and TX – are offered in 50 and 60 grams.  At 70 and 80 grams, Mitsubishi offers stiff, X, and TX.


After such a glowing review, you might be wondering if the Mitsubishi TENSEI Pro White 1K is going in my bag.  It absolutely is.  The numbers I got from it were sensational, but more importantly I love swinging it, and I have great confidence in it.  If you want to see what the most premium version of TENSEI can do for you, head to you fitter to test the Pro White 1K.

    Did you test other 1K shafts, in other weights?
    (50TX has been loved by other tester…)

    Great review, I’ve been waiting for this one.
    Did this knock the Ventus black out of the bag? Or were you in something else?
    Cheers mate

      I had the Nippon Regio Formula MB+ in the bag between the two. All three are outstanding, and I could honestly game any of them.


  3. Matt- With club head speed clocking in at 109, that’s a few MPH higher than your other reviews. Do you attribute this to confidence in the shaft or a change in golf fitness regimen?

    • Matt Saternus


      Neither, I’ve just been healthy for a bit for my speed has ticked up. Over the last year or so, there have been a lot of small injuries that have kept my speed down a bit.

    Hi Matt,

    Great review! What head did use, G425 Max?

  5. Peter Gustafsson

    When you refer to the “Standard Tensei” would that be the Pro or Non-Pro version?

  6. Hi Matt,
    Do you think you would have lost the tight dispersion had you played the S flex or do you think the tip would remain pretty stable at your swing speed?


    • Matt Saternus


      I don’t think 105-110 MPH is going to “overpower” the S flex, but I suspect that I would not be as comfortable with the way it feels.
