2020 Mizuno E21 wedges: High performance reimagined

Published

on

New design, new construction, and a new way to look at what a high-performance wedge can be—these are Mizuno E21 wedges.

When talking about new clubs and the technology being utilized by engineers, the conversation eventually turns to mass properties and how adjusting them within the clubhead helps to create higher-launching lower-spinning shots. This is great when talking about drivers and fairway woods, but at the other end of your bag, high-launching, low-spinning shots are the enemy of great wedge play and distance control.

The key to hitting lower-launching, higher-spinning wedge shots is making contact below the center of gravity lower on the face. To help players achieve these optimal launch conditions, the Mizuo E21 utilizes multipiece construction to place the center of gravity higher in the head than ever before.

Mizuno E21 wedge technology

Mass properties play a massive role in the performance of any club. By design, wedges are the heaviest full swing clubs in the bag. This gives designers more mass to move around. To get the most of the Mizuno E21’s performance, the focus was to relocate as much mass higher and deeper in the head without sacrificing both looks and feel. The only way to do this was by using a hollow body construction.

The E21 wedge brings together a 1025 Grain Flow forged boron face and hosel with a 431 Stainless steel back, this helps the wedge maintain the soft and solid feel Mizuno is known for while also increasing groove durability. Don’t think that because a wedge is packed with technology it makes it a club meant for higher handicap golfers either—any golfer can benefit from improved wedge technology, the same way we can all benefit from hitting higher launching, lower spinning drivers.

The new E21 wedges even offer the exact same, if not thinner appearance from address than the Mizuno T20’s even though the back of each wedge looks extremely different—again, just like with drivers, something that looks different is different for a reason.

Soles designed for versatility

Beyond the new and improved mass shifting the E21 wedges provide, the most important part of the wedge is the sole, and Mizuno R&D pulled out all the stops when configuring the soles of these wedges to fit a wide variety of players.

They come in both a narrow and wide sole option, but unlike with irons where a wide sole is generally reserved for game improvement clubs, the wide sole models of the E21 have been configured for maximum versatility. Mizuno is not the only OEM offering versatile wider sole wedges, Callaway has the “X” grind, and Titleist with the low bounce “K”, to give you a few examples.

The wide sole E21’s have a lot of heel and toe relief along with a lot of front and back camber to keep the leading edge closer to the ground for those tight lies around the greens.

Mizuno Hydroflow Micro Grooves

Just like with last year’s release of the T20 wedges, instead of using traditional laser etching parallel to the milled grooves, Mizuno engineers took the concept of tread from high-performance tires and went perpendicular to the grooves and parallel to the direction the ball moves up the face to channel moisture away.

This directional tread has proven to increase spin on shots especially in conditions with moisture up to 1,200 RPM on a 60-yard shot. It’s not just about spin either: the more the friction created also means more control on launch angle and less of a “floating” ball flight. That’s how those low flying “zippers” really zip!

The other part of this groovy tale has to do with the reconfiguration of the grooves. Just like with the T20, the lowest groove on the E21 wedges has been shortened and centered. This puts it closer to the leading edge without having it disorient the look of the club from address and making it appear that the heel or toe is thinner on one side.

By bringing together the new CG placement with leading groove technology and reconfigured soles, Mizuno is once again changing the way players think about wedge performance.

New Mizuno JPX923 irons: Everything you need to know

Published

on

What you need to know: Mizuno is launching the successor to its JPX921 series. Engineers leveraged the company’s custom-fitting program — including data from 350,000 golfers — in the creation of the JPX923 series, which includes five models: JPX923 Tour featuring a new V-Chassis and thinner topline, JPX923 Forged with features Mizuno’s third generation of chromoly forging, JPX923 Hot Metal, JPX923 Hot Metal Pro, and JPX Hot Metal HL all featuring new, faster 4335 nickel chromoly, which is 35 percent stronger than Mizuno’s original chromoly.

Mizuno JPX923 irons: What’s new, key technology

JPX923 Tour

Featuring a copper underlay for “Mizuno feel,” the JPX923 Tour is one-piece Grain Flow Forged in Hiroshima Japan from 1025E Pure Select mild carbon steel. Narrower top line and sole in tandem, more rounded trailing edge for cleaner turf interaction.  Features Mizuno’s new ‘V-Chassis’.

“The goal was to engineer a compact, players cavity back that looked and felt like a muscleback at impact. With the copper underlay and new topline, the JPX923 Tour is right there,” says David Llewellyn.

JPX923 Forged

Mizuno’s third-generation of chromoly forging places a wider milling slot heel to toe in the 4120 chromoly 4 through 7-irons as well as well as a thinner clubface. JPX923 Forged are mid-sized, full body Grain Flow Forged irons with a thinner topline and bevelled sole throughout. The scoring irons (8-GW) also feature more compact design and are forged from 1025E Pure Select mild carbon steel.

“The new JPX923 Forged pulls off two impressive achievements. First it feels more solid even though it’s faster from the face. Second, it looks sleeker with a thinner topline and narrower sole even though it plays more forgiving,” says Chris Voshall, Mizuno’s Director of Product.

JPX923 Hot Metal, Hot Metal Pro, Hot Metal HL

With the JPX923 Hot Metal, Mizuno introduces “4355 nickel chromoly,” which is 35 percent stronger than the original Hot Metal material and allows for an eight-percent thinner clubface. Cup face construction works in tandem with a deep center of gravity for high launch with stopping power.

Mizuno developed Hot Metal Pro, Hot Metal and Hot Metal HL (High Launch) from 175,000 real golf swings recorded via Mizuno’s Swing DNA system and describes the three models as follows.

  • JPX923 Hot Metal Pro is a player’s speed cavity that’s compact, with minimal offset for confident ball-strikers seeking maximum ball speed. It’s suitable for low to mid handicap golfers.
  • JPX923 Hot Metal is a forgiving speed cavity suitable for mid to high handicap golfers. It features a full speed, high stability cavity for straight flight and distance.
  • JPX923 Hot Metal HL is a high launch speed cavity delivering a higher launching option for players with moderate swing speeds or aggressive shaft lean, it’s suitable for mid to high handicap golfers.

What Mizuno says

“The new JPX923 series was planned out with Mizuno’s custom ethos at its core” says David Llewellyn, Director of R&D for Mizuno. “We already offer more than 50 unique shafts within our custom program, by expanding to five iron models, there’s an ideal combination for every type of player.”

“We’re constantly evolving the JPX series based on more than 175,000 unique swings we capture every year on the Mizuno Shaft Optimizer,” says Bill Price, Mizuno’s Director of Fitting. “Recently we’re seeing an increase in the number of players with slightly slower swing speeds being fitted – and a trend to more shaft lean. Hence a slight increase in bounce angles through all the models and the introduction of the Hot Metal High Launch.”

Resident Club Junkie Brian Knudson’s take

Note: GolfWRX has not yet gotten an in-hand look at the JPX923 Tour or Forged irons. 

Mizuno’s Hot Metal HL irons look easy to hit and high flying with their larger sole and longer heel to toe shape. You can see some of the tech that is packed into these irons around the badge like the Harmonic Impact ribs and the Stability Frame. Like you would expect from Mizuno the finish quality and badging all look very good and catch your eye without the need for wild colors.

The Mizuno Hot Metal irons look to be the bread and butter of the lineup. The Hot Metal features a little smaller footprint than the HL, less offset, thinner top line, and narrower sole. The look from address will please most golfers and it is still packed with the technology for easy distance and effortless launch.

Hot Metal Pro irons are the smallest of the three but should still offer a great combination of looks and performance. They are still a little longer from heel to toe while offering the least offset and thinnest toppling of the group. The short irons are shaped really well and the whole set flows great from 4 iron down to the pitching wedge.

Mizuno introduces new JPX Fli-Hi

Published

on

Mizuno has today introduced the JPX Fli-Hi in a bid to meet every golfer’s demand for greater playability and easier ball-flighting potential at the longer end of the bag.

“We see a lot of players with moderate swing speeds who hit many of their longer irons the same distance – they just don’t have the clubhead speed or consistency of strike to launch the stronger lofted clubs. The JPX Fli-Hi is designed to give those players more practical distance gaps and consistency of flight.” – Chris Voshall, Mizuno’s Director of Product

The new addition features a 17-4 stainless steel face and 431 SS body in a bid to deliver an upgrade in ball speed, while the bendable hosel allows for adjustments in lie angle.

The clubs feature a lighter crown which allows for a higher ball flight, while a re-engineered Wave Soleplate is designed to increase the effective high ball-speed area of the Fli-Hi’s clubface to deliver more consistent ball speeds.

The JPX Fli-Hi is designed to slot seamlessly in to a set, with the models from #4 to #7 designed to correspond directly to the irons they have been created to replace.

The JPX Fli-Hi range features a graduating profile from fairway wood to hybrid to maximize playability. The 20 degree (#4) has a wider fairway type profile, moving towards a tighter hybrid type shaped 29 degree (#7) with a deeper face.

With a deeper center of gravity than the replaced iron, the JPX Fli-Hi is designed to produce more predictable launch and spin rates, thereby more reliable distance gaps between clubs.

The JPX Fli-Hi hits retail this month and costs $137.50 per club.
