Spotted: Nippon “Graphite On Steel Technology” hybrid prototype shafts

Published

on

Steel vs. graphite shafts, which is better for your game? It’s a question as old as the invention of graphite shafts for golf clubs.

Well, it appears that Nippon is combining steel and graphite with its new hybrid prototype shaft, with technology called “Graphite On Steel.” Based on the nomenclature and the photos we captured at the 2018 AT&T Byron Nelson on Monday, it seems that there is a layer of graphite surrounding a steel hybrid shaft.

And for what purpose? GolfWRX Members are guessing that the design could be for reduced vibration, or for great stability, but we’re yet to know for sure.

We’ve reached out to Nippon representatives and will update this story with more information as it becomes available. For now, click here for more photos and discussion.

    In the 90s I reshafted the bimatrix shaft for many customers. That shaft incorporated the same principles and proved to be more hype then substance! With that shaft I found the swingweights to be too high!

    I too have a set of the Aerotech SteelFiber shafts which have steel thread wrapped around a graphite core and they were great, but a couple years ago I put Fujikura’s Metal Composite shafts (MCI) on my Calloway Apex irons and Wow! they are terrific shafts. Like the Nippon shafts, they have a graphite sleeve over a steel core shaft. Don’t know there’s a ton of difference but the Fujikura seem to have the perfect Flex and torque for my swing.

    A side from perhaps the steelfibers (never tried), has anyone even had much success intertwining steel and graphite?? Would think the extra labor/technology involved would largely go unnoticed by many and likely to be not worth the production cost.

    Graphite Hybrid On Steel Technology or GHOST for short
    Should make them in white

    This technology looks to be very similar to Aerotech Steelfiber, who advertises that their shafts are longer and straighter with less effort and they avoid injury or aggravating previous injury.

      so yer regressing back to woodies and abandoning stiff steel and floppy graphite?

    SteelFiber shafts have filament-wound steel fibers over and internal graphite shaft… and now Nippon is putting the graphite over the steel shafting. Why are they doing this expensive solution to compensate for the failings of plain graphite shafts with floppy soggy tips with a sloppy dynamic response going through final release and impact?

      Furthermore.. most graphite shafts are oven-cured to harden the epoxy mix holding the graphite fibers. Not with Seven Dreamers graphite shafts which are autoclave cured that sucks out the excess epoxy plastic that causes the tip instability of other graphite shafts.

      Steelfiber convert here… I agree why put the graphite on top of the steel? Doesn’t make as much sense as the steel-fiber-weave wrapped around a traditional graphite shaft…

Mizuno announces new JPX 919 Tour Forged irons are coming August 29 (via cryptic Twitter post)

Published

on

While cryptic, it does appear Mizuno is announcing via Twitter that its new JPX 919 Tour irons are coming on 8/29/18. One would have to assume that means they will be launched on 8/29, not actually hitting retail on 8/29, but that remains to be seen.

We recently spotted a number of new irons on the USGA conforming list, including the JPX919 Tour irons pictured above, JPX919 Forged and JPX919 Hot Metal irons from Mizuno. So it’s likely that the JPX 919 Tour Forged irons won’t be alone in the JPX 919 family when they hit retail.

The JPX 919 Tour iron specifically pictured in the Tweet above seems to be the replacement for Mizuno’s JPX 900 Tour irons that Brooks Koepka used to win this year’s U.S. Open and PGA Championship. Learn more about the original JPX 900 Tour design from Mizuno’s Chris Voshal on our Gear Dive podcast.

Diving a bit deeper into the picture from Mizuno’s Tweet, it appears the JPX919 Tour irons will utilize Mizuno’s familiar Grain Flow forging, and will be made from 1025E; that’s based on the hosel stamping that says “GF Forged HD 1025E.”

Stay tuned for more info from Mizuno.
