2020 Mizuno JPX 921 Forged, Tour and JPX921 Hot Metal irons: Faster, farther, better



New for 2020 Mizuno golf are 4 sets of irons. JPX 921 Tour, JPX921 Forged, JPX921 Hot Metal and the JPX Hot Metal Pro.

It has been 10 years since Mizuno initially launched the JPX iron series with the JPX 800. Since that time, iron after iron, engineers have introduced innovations that have allowed the company to push both cast and forged iron performance to places never before seen—and they are doing it once again with the release of the Mizuno JPX 921 iron series which includes the JPX 921 Tour, JPX921 Forged, and JPX921 Hot Metal—alongside the Hot Metal Pro.

Before diving into what’s new, we have to take a look back at the 10-year history of the JPX line, because from where it began to where it is today is an almost unrecognizable transformation.

But before we get to that first, let’s ask the question: What does JPX stand for?

Answer: Japan Performance Extreme.

It was a name developed for the Japanese market as a way to introduce more aggressive, distance-driven, often cast irons to a different segment of the market. Mizuno even went as far as creating branded anime comics featuring Mizuno’s Mr. X—alongside some of its staff players including Luke Donald—seriously.

More photos and discussion in the forums. 

After being introduced in Japan, in 2011 the JPX line replaced the previous MX line in North America (which dated back to 2002 with the T-Zoid MX20). The JPX brand offered solid performing game improvement clubs that introduced a lot of new golfers to the generally better player-focused Mizuno. From there, a year later came the JPX Pro line to offer Grain Flow Forged construction with a game improvement twist to help golfers who still wanted a forged club with a little extra forgiveness.

Along the way, Mizuno introduced some great clubs—along with some they would rather you forget (JPX EZ, anyone?), but the brand was always been about reaching beyond Mizuno’s comfort zone and offering something to push the envelope.

The interesting thing about the JPX brand evolution is that what started in Japan became a bigger hit than they ever expected in North America, which lead to engineers creating designs more catered to the North American market to them bring back to Japan. It is an interesting change of fortune that started with the JPX 900 series and continues to this day, with the introduction of the newest JPX series, the JPX 921.

Mizuno JPX921 Forged: New processes lead to innovation

Let’s start with the biggest evolution: the JPX921 Forged.

“Faster – Forged – First”. It’s what Mizuno is using to describe its all-new JPX 921 Forged, and by appearances, they are right on every account. If we look back at the JPX Forged series, of irons or as it was previously known as the “Pro” series, they have always been about pushing the envelope of speed, shotmaking performance, and feel through material and geometry innovation. Thanks to a material and process change, the new JPX 921 Forged deliver more ball speed from a smaller chassis—it’s like they put a bigger engine into a smaller car…or have made a smaller trampoline return more energy. It takes a serious engineering step to get there.

The Materials

If you are familiar with modern Mizuno iron history then you have already heard about Chromoly when discussing the particular metal used in the construction of irons, but if you haven’t, let me help get you up to speed. It was first used in the JPX 900 Hot Metal irons to achieve improved cavity strength and face flexibility for more speed, while also still being malleable enough to bend for custom lies and lofts—a common issue with other game improvement clubs.

It was then used again to cast the JPX 919 Hot Metal and Hot Metal Pro irons to achieve higher ball speeds and increased MOI. The JPX 919 Hot Metal irons have gone on to be one of the most popular irons Mizuno has ever made and helped the company gain sizeable market share in the competitive game improvement category.

This brings us to the next big jump when Mizuno, along with its exclusive forging partner Chuo, in Hiroshima, Japan, Grain Flow forged the strong flexible Chromoly material for the first time in the construction of the faces and hosels components of the MP-20 HMB’s (2- 8-irons) for increased ball speed off the face of a hollow forged iron. It was another way to blend together process and materials innovation to build better performing golf clubs.

More photos and discussion in the forums. 

The next material innovation: One-piece Grain Flow Forging Chromoly

Now for the first time, the Mizuno JPX 921 Forged is a one-piece Grain Flow Forged Chromoly iron. This allows engineers to completely re-engineer the geometry of the club to deliver a more compact players look with higher MOI and faster ball speeds thanks to a thinner face construction—oh, and don’t forget, better feel too! In the history of the JPX line, the 921 Forged is the most compact “Forged” model ever created.

This is not the first time Mizuno has used a new material to gain a performance advantage with a JPX “Forged” iron either. It was in late 2014 when Mizuno introduced the JPX 850 Forged which added Boron to the 1025e Pure Select Carbon steel to create irons that progressed the line and enabled thinner faces for more ball speed. Unlike the MP line of irons, where feel, looks, and workability take the main focus, JPX is and has always been about placing a premium on distance without sacrificing the other characteristics Mizuno irons are known for.

As much as it seems like a simple progression, Grain Flow Forging the Chromoly steel requires extra steps to get it to where it reaches the final dimensions as a club head. Whereas all other forged Mizuno irons before have gone through two precision forging hits, the JPX 921 goes through three. This means more molds, more steps, and more precision.

The last part of the 921 Forged story is the back milling of the sole. This started with the 919 Forged and continues with the 921. Thanks to the new stronger material, the side to side measurement of the slot and cavity is more than six-percent wider than the previous model, resulting in a what Mizuno is calling a 45 percent increase in total COR area of the face. When reengineering anything single percentage points matter, and the fact that Mizuno can widen the slot by more than six percent is a very significant number—especially when you consider this is a more compact head than the previous generation.

When you add it all up, what the designers and engineers at Mizuo have been able to achieve with the JPX 921 Forged will appeal to a wide swath of the golfing population. From low handicap golfers who want extra help and confidence in their irons thanks to the slightly larger shape to mid-handicap golfers that who a more compact one-piece forged club iron but aren’t quite ready for a small players cavity.

JPX 921 Forged: Specs, price, and availability

The stock components are Nippon Modus 120 in Stiff flex and 105 in regular with Golf Pride MCC+4 Grey grips. The JPX 921 Forged will only be available in right hand.

The price will be $175 per club/$1,400 for an eight-piece set.

Mizuno JPX 921 Tour irons

As much as the JPX Forged line is about advancing technology and materials, the 921 Tour is about subtle refinements to deliver familiar performance with improved feel and looks. Another way to say it: “Let’s not screw a really good thing up.” Even in its short time as a Mizuno iron, the JPX Tour—starting with the 900 and then the 919—could be considered one of the company’s most important irons ever designed that came along at just the right time.

To quickly rehash an old story now, when Nike left the equipment space in 2016, it left a lot of golfers on tours all over the world searching for new clubs. Some chose to quickly sign with other OEMs while some other players (Brooks Koepka included) chose to forego club contracts and just use whatever clubs they felt worked the best—it was the rebirth of equipment free agents on tour. The irons Brooks ended up using to win all for of his current majors were the 900 Tours for the first three and then the 919 Tours for his most recent PGA Championship. Not to mention they were also the top money-winning iron on the PGA Tour in 2019 by non-contracted players.

The JPX921 Tour is designed with the feel, flow, and performance of the MP series but with greater clubhead stability and a different player in mind. The MP could still be considered the “traditionalist” iron, whereas the JPX Tour caters to a more aggressive player needing a little bit extra help on occasion but still wanting a smaller looking iron.

This is where Mizuno’s Stability Frame design allows the 921 Tour to offer greater forgiveness (higher MOI) than the MP-20 MMC without the multi-material construction. Designers achieved better flow by narrowing the soles in the shorter irons and ever-so-slightly increasing the width in the longer clubs—not something noticeable from address but a feature that helps with ball flight control.

The last, and quite possibly the most important part is looks and feel, and Mizuno took an old school approach to get this right for the 921 Tour. The first part was feel. To get the impact harmonics where they wanted engineers thickened the pad behind the impact area without losing the desired MOI. The original 900 offered thickness but less stability, the 919 went a bit thinner to boost MOI, and now the JPX 921 Tour is like Goldilocks finding the bowl of porridge that was just the right temperature.

So, about those looks. For the first time with the JPX series, after final CAD models were produced, they were sent to the Mizuno craftsman for final shaping before becoming master models for production. This process was always reserved strictly for the Mizuno MP line of clubs, but since the designers and engineers wanted to do everything they could to have the newest JPX 921 Tours look absolutely perfect at address and in the bag, they took every step they could to deliver on that goal. To understand that process more, check out the video below from the release of the MP-18 irons.

JPX 921 Tour: Specs, price, and availability

The stock components are KBS S-Taper Stiff flex with Golf Pride Z-grip full cord grips. Only available in right hand.

The price will be $162.50 per club/$1,300 for an eight-piece set.

Here is another first of the JPX 921 Tour irons—no 3-iron available. Similar to how Mizuno analyzed the number of custom ordered sets to produce SKUs for the MP-20 line, the company decided it was finally time to do away with the 3 and instead offer a matching gap wedge. It’s a minor detail, but if if you are looking to add a 3-iron to your set, the 921 Forged 4-iron is a perfect three-degrees stronger and has a hotter face—just food for thought.

Mizuno JPX 921 Hot Metal, Hot Metal Pro irons

Similar to the JPX Tour, the designers at Mizuno didn’t want to mess with a good thing—they instead just wanted to reevaluate how they looked at the JPX line as a whole and make changes to suit the intended target golfers and well as make them look even cleaner. JPX irons have come a long way in the looks department since the original JPX 800 (below)

With 921 Forged moving into a smaller platform, it gave the designers at Mizuno the opportunity to do something they, along with a lot of other OEMs, have done in recent years—create a better-flowing set from top to bottom means more forgiveness where you need and control where you want it.

From left to right: JPX-921 Tour, JPX-921 Forged, JPX-921 Hot Metal Pro and JPX-921 Hot Metal

With the 921 Hot Metal, that means starting at the 8-iron and moving into the longer clubs, the heads lengths have gotten just a little bit bigger from heel to toe to boost MOI. This longer blade allows for a slightly lower center of gravity to accommodate the one-degree stronger lofts to add distance while maintaining peak hight and descent angles. Just like how the Forged model got smaller yet faster thanks to a material change, the material used to craft the 921 Hot Metals hasn’t changed—instead engineers changed the geometry to improve performance.

The other changes include adding three new sound ribs to the top line to make it lighter and stiffer and to enhance acoustics while also saving weight to redistribute around the head and Stability Frame.

Last but not least, we can’t talk about a game improvement iron without talking about ball speeds and face engineering. Mizuno separates itself by making the entire head including the seamless face cup completely weld-free, that’s right, one-piece construction other than the badge. The 921 has the thinnest fastest face that have ever produced

Hot Metal: Specs, price, and availability

The stock components are Steel: Nippon NS Pro 950 NEO, & Graphite: UST Recoil EXS with Golf Pride MCC+4 Grey grips. The JPX 921 Hot Metal irons will be available in right and left hand, with the standard set makeup of 4-GW.

The price will be $125 per club/$1,000 for an eight-piece set.

Now to the Pros…

In the early part of 2019, Mizuno did something a little out of character for the usually very predictable Japanese company—it released a line extension iron mid-cycle with the JPX 919 Hot Metal Pro. Even though it was a bit of a surprise, the reaction from golfers was beyond positive. Now with all four JPX 921 series irons being launched cohesively, it will give players looking for Hot Metal ball speed in a smaller package the option right from the start.

The Pro offers all of the Mot Metal technology as the standard model, but what separates it from the standard model is the look from address, including the topline – thinner, blade length – shorter, and offset – in line with the player focused MP series.

Also, much like the standard Hot Metal, the flow was improved from top to bottom with the 7 iron being the starting point for a slightly longer blade length into the longer clubs. To be honest, you’re going to have to look very closely to notice it, but it’s there, and it’s there to help.

Hot Metal Pro: Specs, price, and availability

The stock components are Project X LZ Black 5.5 with Lamkin ST Hybrid grips. The JPX 921 Hot Metal irons will be available in right-hand only with the standard set makeup of 4-GW

The price will be $125 per club/$1,000 for an eight-piece set.

There are always more options

Like with previous generations, including MP irons going back almost a decade, Mizuno is sticking with its industry-leading matrix of shaft and grip options available at NO upcharge. However, after 2019 and growing demand for more exotic shaft options, the newly expanded Mizuno shaft line up will include a few shafts that will come with a slight upcharge. The full list of shaft options can be found at

    Thank You Ryan!!!

    Why have they ignored left handers for hot metal pro again. Very disappointing

      Concur! Even more disapointing is no Forged left handed version (which we have had in previous generation models.) WTF Mizuno!

        Aug 11, 2020 at 9:09 am

        I agree completely. I think they will be offering a set of JPX921 SEL for lefties which will consist of a JPX 921 forged 4, 5 iron & 6-GW 921 Tour irons. That’s fine but all I really wanted was the 921 HM pro’s in LH. Not sure who is making decisions at Mizuno but as a Lefty I could not game a whole bag of Mizuno clubs because there is not enough options.

    More it looks like clubs have reached a point where making them work better is not a issue..seems going after making the good performing clubs look amazing is the selling point now. Getting to where I can hardly stand to look at the new Ads for new clubs every month…can have a hundred pair of shoes in my closet but filling the garage with clubs is getting old.

      For me, the feel was not Mizuno. Felt more like bargain store specials. Also, dispersion was quite disappointing. After 30 holes, they found themselves in a new home.

    Aug 10, 2020 at 10:17 am

    These look nice. Only the Tour has the length listed – 38.5″ 5-iron and 36″ wedge. Looks like Mizuno have bumped their stock lengths quite a bit. Probably trying to adjust based on their typical orders.

  7. Paul Runyan

    Aug 10, 2020 at 10:08 am

    JPX 921 5 iron at 38.5 inches? Isn’t that a little long for a standard tour iron?

    Or am I reading this incorrectly?

    It looks like length increased by over 1/2 inch from last years spec of 38.0 inches.


    • Ryan Barath

      Aug 10, 2020 at 2:59 pm

      The stock lengths have NOT been increased over previous models – there was shifting during data transfer when doing the graphics that caused the miss, and they have been updated to the correct information.

2021 TaylorMade SIM2 Max and SIM2 Max OS irons



The 2021 SIM2 Max and SIM2 Max OS irons from TaylorMade are about bringing together key technologies from the previous generation and combining it with their all-new Cap Back cavity design to increase distance with more face flex and improve sound by completely changing the cavity design.

What’s new in the SIM2 Max irons

2021 TaylorMade SIM2 Irons

What started out as SpeedBridge, which we should note would make a great title for a Keanu Reeves action thriller/car movie that somehow has its culminating scene take place on a bridge, in the SIM Max and SIM Max OS irons has evolved to something bigger—dare we call it a sequel—with the all-new Cap Back.

What is Cap Back?

SIM2 Max iron Capback

The Cap Back design of the new 2021 SIM2 Max irons replaces the metal speed bridge that ran from the rear of the sole to the top line of the 2020 models. This little strip of metal created tension to help support the topline and allowed engineers to bring more weight from the top of the iron low to lower the center of gravity and increase launch.

2020 SIM2 iron with SpeedBridge

It also allowed the face to flex like a big oversized tennis racket to create more ball speed around a larger area.

The new Cap Back is a full cavity encasing polymer cap that connects and supports the topline without touching the face. It helps produce a higher MOI since the polymer material is seven-times lighter than the steel counterpart per g/cm3 and frees up more mass to be moved low in the head to raise stability—especially for shots missed around the face, which for golfers that fit into this iron category and going to do.

Faster Sim2 Max face

“We set out to take game improvement irons to the next level with SIM2 Max and SIM2 Max OS. To create Cap Back Design, we utilized multi-material advancements learned from our metalwoods to unlock forgiveness and distance with forged iron like feel. We leveraged a completely new construction to achieve the performance that golfers in this category both need and want.”

– Matt Bovee, Product Creation | Irons Category

SIM2 Max and Max OS iron technology

2021 TaylorMade SIM2 Max OS irons cavity

All-new Echo Damping System

Beneath the Cap Back and behind the face on the new SIM2 Max and SIM2 Max OS irons, you will find an improved Echo Damping System which features a more concentrated HYBRAR material. The damping system stretches across the entire face (from heel to toe) using multiple contact points and also utilizes a softer polymer blend to channel away more unwanted vibrations.

SIM2 Max OS vs. SIM2 Max sole profile

This vibration channeling helps contribute to what TaylorMade likes to call a forged-like feel while still promoting maximum face flex.

Progressive Inverted Cone Technology

TaylorMade’s Inverted Cone Technology (ICT) is strategically positioned into each SIM2 Max and SIM2 Max OS iron as a way to help increase the sweet spot and minimize mis-hits.

The reason for this is shots hit on the toe of longer irons generally result in a miss to the right, TaylorMade engineers have positioned the ICT towards the toe in both SIM2 Max and SIMs Max OS irons to counteract this. Through this move, the engineers have created a draw bias in the longer irons to minimize this common miss without resorting to adding additional offset typically found in larger game improvement designs.

Other technology carryovers from the previous generations that can be found in the SIM2 Max irons include the fluted hosel, 360° undercut cavity -now positioned under the polymer cap back, and an ultra-thin face.

What makes the Max OS irons different?

Sim2 Max OS vs Sim2 Max from address

The SIM2 Max OS irons are everything the SIM Max irons are and more, including everything you would expect from a maximum game improvement irons are packed with all the same technology of the SIM2 Max irons but put together in a wider-soled, lower CG, stronger lofted, more draw-biased package to help golfers that are looking for every advantage.

Specs, pricing, and availability

The SIM2 Max and Max OS irons will be available for preorder starting January 19 and will be in retail locations beginning February 10.

Both sets will be priced at $799 steel (KBS Max MT 85 steel ) and $899 graphite (Fujikura’s Ventus Blue graphite, 7S, 6R & 5A) in 7 piece set configurations 4-pitching wedge – which is a departure from the way TaylorMade has assembled stock sets in the past. This allows golfers to choose whether they would prefer to order the matching wedges for the set – which include a gap wedge, sand wedge, and lob wedge, or go with something else to find proper gapping.

The SIM2 Max and SIM2 Max OS irons will also be available for women and come outfitted with the Aldila NV Ladies iron shaft and the Lamkin Ladies Sonar grip.

2021 TaylorMade SIM2 drivers: Better performance, piece by piece



TaylorMade is building upon the SIM driver platform with 2021 TaylorMade SIM2, SIM2 Max, and SIM2 D drivers.

With the launch of the SIM driver series in 2020, TaylorMade proved it could build drivers that offered low spin performance in three different configurations to enhance speed and fit golfers better to reduce dispersion. For 2021, engineers are taking the SIM driver platform further with the launch of the SIM2—including the SIM2 Max, and SIM2 Max D (draw)—by refining the package piece by piece to deliver better performance throughout the entire line.

2021 TaylorMade SIM2 drivers

2021 TaylorMade SIM2 drivers

What’s new, and what you need to know

  1. Designers have taken every step to look at different materials and configurations to add forgiveness while maintaining the low spin characteristics of the original 2020 SIM design.
  2. No more sliding weight track. The sliding weight on the standard model has been removed to save mass and increase MOI (a measurement of forgiveness).
  3. Three different models to choose from with greater differentiation to help golfers get dialed in more effectively and find the design that is the best fit.
  4. More precision built into every part of the driver. The only way to make a golf club, especially a driver, better, is to maximize the weight properties and geometry. By painstakingly looking at every single component and manufacturing process, that’s exactly what TaylorMade has done.

The technology inside and out

What’s the same? What has gotten better?

Speed Injected Twist Face of the TaylorMade SIM2

Twist Face technology: Since its introduction in the M4 and M4 drivers, this redesigned bulge and roll profile helps keep shots missed around the face online and closer to the center while also normalizing spin to increase consistency.

2021 Speed Injection port

Speed Injected face: Speed Injection was introduced with the M5 and M6 drivers. It allows TaylorMade to calibrate each clubface right to the legal limit of CT without going over. With the new SIM2 drivers, this manufacturing process and the system used to dial it is have been moved and improved to save weight and further fine-tune face performance.

New heavier Inertia Generator at the rear of the SIM2 head.

Inertia Generator: The extremely low and rear placed mass helps position the CG low and away from the clubface to boost MOI. With the new SIM2 drivers and the weight savings accomplished around the head, this weight is now heavier to increase MOI and drive the center of gravity lower.

Three models: The SIM2 driver family features three distinct models to help golfers find the right performing driver for them.

Improvement piece by piece

As mentioned off the top, the engineers at TaylorMade looked at every part of the driver to improve performance and increase forgiveness, so let’s take a deep dive into each component and put it all together.

CNC Milled ICT (Inverted Cone Technology) and redesigned Speed Injected reservoir

Speed Injected resin reservoir

TaylorMade is taking its face precision to the next level by CNC milling the ICT (TaylorMade’s patented variable thickness face technology) into the back of the face. Other OEMs have started to use milling around the face of the driver in a different variation, but this is a first for TaylorMade and allows engineers to also remove a reservoir from the injection process.

By eliminating one of the front reservoirs and only having one positioned behind the face, engineers have been able to remove the dual injection ports from the face and place a single port on the toe. Less is more when it comes to drivers, and less structure and mass in the front of the driver head frees up precious grams to be redistributed.

Carbon composite crown

Lightweight carbon crown

To say that the carbon crown on the SIM2 is revolutionary would be a stretch, but it is still a key part of what allows the designers to save mass and position it lower in the head and around the perimeter. The carbon crown of the SIM2 is comprised of six layers and comes in at just over 10g grams, meaning it holds less than five percent of the clubhead’s total mass.

Carbon composite sole panel

Carbon soleplate of the SIM2 driver

TaylorMade has used carbon in driver soles before, but it has never used it to make up the entire sole. By eliminating the sliding track, and the reinforcing needed to house the weights, it can utilize carbon from behind the face all the way to the extreme rear of the head where it attaches to the forged titanium back ring. Compared to the crown, the sole is comprised of nine layers of carbon fiber and only weighs 12 grams.

Although not part of the carbon sole panel, the other very noticeable new component is what TaylorMade is calling the “TPS Weight” for swing weight customization. If there is one part of the custom build puzzle TaylorMade has struggled with in the past for consumers it has been the ability to dial in requested swing weights—either because of length or custom shaft and grip combinations. With the SIM2, the folks at TaylorMade are hitting home it’s focused effort to deliver better at every turn, and this small weight results in a big change to their build process.

Forged aluminum back ring chassis

Forged aluminum back ring of the SIM2 driver

This is a whole new territory and a very cool part of the SIM2 driver’s story. Using a forged, CNC milled aluminum ring around the rear of the head saves mass that would have otherwise been taken up by titanium.

Milling on the inside of the SIM2 driver

The aluminum ring weighs almost exactly 20 grams. Titanium, compared to aluminum, is 1.67 times heavier (4.5g/cm3 vs 2.7g/cm3) so the ring saves 13 grams, which would have otherwise placed mass higher in the head. Those 13 grams are reposition in the heavier inertia generator and low in the driver to once again improve forgiveness.

When you put it all together, it is truly better piece by piece.

The 2021 TaylorMade SIM2 driver models

TaylorMade is doing everything it can to eliminate any confusion when it comes to differentiating the SIM2 models, so let’s break down the type of golfer each one is designed for.

2021 TaylorMade SIM2

2021 TaylorMade SIM2 driver

The standard model is the lowest spinning of the three new drivers and has the most forward CG to offer on average 250 rpm less spin than the Max, while still maintaining stability. The stock rear weight is 16 grams and it has a larger face than its predecessor to increase confidence and make the club more forgiving overall.

The SIM2 Max features a massive 24 gram back weight to deepen the center of gravity and boost stability even more. When you factor in the average driver head weight is around 203 grams, this back weight makes up almost 12 percent of the total mass, which is what helps create so much stability.

The face has also been made larger in the SIM2 Max compared to the previous model to help inspire confidence while still offering a neutral ball flight and not sacrificing any of the aerodynamic properties.

With the SIM2 Max D, the entire goal is to help reduce a fade, and that is achieved by moving the rear inertia generator weight more towards the heel and also moving the TPS weight to the outer heel area.

The Max D has the largest face area of the three models, which also helps those golfers who struggle with constant face contact.
