Callaway legitimately revolutionized irons when they first introduced the APEX lineup way back in 2014, the blending of forgiveness and all-out performance had never been done like that before. Not only that, but with each subsequent release the accolades have grown as has the amount of tech the company continues to pour into them.
What that has led to is an incredible amount of anticipation each time we edge closer to the unveil of the next iteration. Well, the Callaway Apex 21 lineup is coming, and it’s bringing a new friend with it.

The New Apex Family
Callaway has taken full advantage of the two-year lifecycle of the Apex lineup to not just bring forth two irons worthy of the family name, but they have brought a third to the party as well. Yes, a third.
This go-round the Apex and Apex Pro will be joined by their little-big brother, the DCB (deep cavity blade) which they believe makes their lineup reach more players than any other generation before it. But more on that very soon.
The Apex irons continue to be the crème de la crème of the Callaway iron umbrella, and with that it is no surprise that they continue to feature the best of all their iron technology developed over the years and rolled into each new version. This is after all the iron series that defined forged irons meeting true forgiveness and playability, literally blurring the lines of classification like never before.
This year the goal was to stretch the tech even more to hit an even broader player profile, while also in their minds not just retaining but increasing their hold as the “#1 Irons in Golf”. Performance and consistency of performance is the goal, and by implementing things like Flash Face Cup, Tungsten Energy Core, and Urethane Microspheres in all three irons, they definitely look poised to accomplish that.
Callaway Apex 21 Irons
It’s only right to start with the flagship iron, right? The Apex 21 is being hailed as a “21st Century Forging” by Callaway, and continues to be a shape and size that will fit the eye of a broad range of golfers. The shaping continues to let them put forgiveness into the iron, but without getting too big nor losing the shot-making potential that has endeared the line to so many over each release.

The goal was to further entrench the Apex as offering leading distance, launch, speed, feel, and most importantly consistency in all of those aspects. To do that they have implemented a “Big Three” of tech, if you will.
First, A.I. Flash Face Cup is here, and it is the first time that Callaway has implemented AI into a forged iron. It was a natural progression given the success A.I. has allowed them in the past couple of years, but it took a lot to implement it into these three sets of irons. This means more distance, but also with more forgiveness all while maintaining spin numbers better than previous iterations. It is also worth noting once again, each iron has a unique face design, both loft for loft as well as compared to the other two Apex sets.

Added to that is a “Massive” tungsten core with a unique split application system low in the iron with heel, toe, and center sections. The unique split placement allows for the increased MOI blended with a lower CG. In all, there is 5-times the Tungsten compared to the Apex 19 irons, ranging from 34g to 64g in the 3-9 while only 14 in the PW and AW to tune in the desired flight through the set. Rounding it out, the 1025 Carbon Steel with Urethane Microsphere technology that continues to be revolutionary compared to anything else on the market for performance and feel.

Callaway is claiming higher peak ball speed compared to the Apex 19, but more importantly the “sweet spot” is much larger and more centered as well as lower than previously which matches where most golfers tend to miss much better. The set will play off a 30.5° 7-iron and 43° PW, but Callaway notes that the A.I. design is allowing them to generate and retain more spin loft for loft than previously possible.
The Apex 21 will be available in 3-AW and paired with all new premium shafts in True Temper Elevate ETS 95’s (R, S) for steel and UST Mamiya Recoil Dart 75’s (L, R, S) for graphite. They are rounded out with Golf Pride Z-Grip Soft for the stock grip options.
Callaway Apex Pro 21 Irons
The Apex Pro irons have long thrived on being a unicorn of sorts, making a more players style iron impressively more playable for a wider range of golfers. Since they have been infinitely successful, Callaway did the only natural thing, they totally and completely redesigned them from the ground up. These are not like any Apex Pro before. Truly.
Welcome the Apex lineup to the age of the hollow body design.

The Pro’s are now a forged hollow body design that Callaway calls a player’s performance iron. For golfers from scratch to single digits who want performance mixed with forgiveness, this may be the ticket, fitting between the Apex 21 and the X-Forged CB.

Hollow is popular right now, but Callaway believes they have done it differently. They liked the hollow body design because it affords more stiffness in the rear of the club but allows a lot to be done internally with the application of the aforementioned A.I. Flash Face Cup, 1025 Carbon Steel with Urethane Microspheres, as well as a massiveamount of Tungsten.

The Flash Face cup is unique to this specific set as well as club for club within the set. When blended with the “Tungsten Energy Core” which has placed 53g to 90g in the 3-7 of the set you have an iron design primed for more speed, more forgiveness, and more spin consistency. Callaway also believes that thanks to the huge amount of Urethane Microspheres both low and higher in the club, and their ability to collapse and rebound without sacrificing energy transfer, they have produced a hollow body with feel like a one-piece forging. Now that is something that will perk up some ears.

The Apex Pro 21 will be available in 3-AW and the set plays off of a 33° 7-iron and 45° PW. Additionally, the premium stock shaft offerings are the all-new True Temper Elevate ETS 115 (R, S, X) in steel as well as the Mitsubishi MMT (R – 85, S – 95, TX – 105) in graphite and paired with the Golf Pride Z-Grip.
Callaway Apex DCB Irons
Rounding out the Callaway Apex 21 irons lineup, the new kid on the block, the Apex DCB.

DCB stands for “Deep Cavity Blade” and the name says it all, this is an even more forgiving forged iron that Callaway wanted to create in order to allow golfers who need a wider sole, longer blade length, and a bit more offset a way to still be part of the Apex family.

All of the above traits meet up with the A.I. Flash Face Cup, 1025 Carbon Steel with Urethane Microspheres, and Tungsten Energy Core just like the other two irons in the lineup, simply in a more forgiving and easier launching package. Though they feature a progressively large sole than the rest of the Apex offerings, they look a lot like the Apex 21’s and visually blend well enough to make a golfer happy when looking down at the clubs.

The Apex DCB will be available in 4-AW and playing off of a 30° 7-Iron and a 43° PW with the set being practically the same as the Apex 21 other than the long irons. Premium shaft offerings for the DCB are True Temper Elevate ETS 85 (R, S) as well as UST Mamiya Recoil Dart 65 (L, R, S) and finished with the Golf Pride Z-Grip Soft.
Combo Time!
Some of you were reading along and wondering, so this is for you…
YES, Callaway will be offering a combo sets for the Apex 21 lineup.
The main option will be the same we saw last time around blending the Apex 21 3-7 with Apex Pro 21 8-AW through the use of unique tooling in the Pro’s to make the set flow as seamlessly as possible. However, they are fully anticipating the possibility of other combo’s created by the consumer or during fittings with the “Apex Sweet Spot” having DCB 4-5 and Apex 21 6-AW, the “Apex Triple Play” with DCB 4-5, Apex 21 6-9, and Apex Pro 21 9-AW, as well as the “Apex Player” featuring Apex Pro 21 3-7 and Callaway Apex MB 8-AW.
The Details
The Callaway Apex 21 irons lineup will begin fitting on 1/28/21 and have a retail date of 2/11/21. Pricing will be $185 per club for steel and $200 per club in graphite.
Be sure to keep an eye on THP for a lot more to come on the entire Apex 21 lineup.
I want to try the 125s.
IIRC from the CF-19 combo set the same “tooling” process was done. The faces and tech stayed the same but tooling allowed the transition to blend easier between sets instead of just picking clubs from each line and making your combo set. I can’t imagine the A.I. Or tech changes just because combo sets are made
Reminder that the Apex Pros shafts will have tapered tips due to the difference in hosel size. Not sure on the tip size of your current shafts, just something to think about
Apex 19 have been a great iron but reading about the 21s is so exciting! As a higher cap I love hearing/seeing the DCB option and even better is an option for combo! Tech sounds amazing and use of AI to push design limits is crazy!
The Apex Pros I had from 16 had those shafts. Same with my XForged from 18 and the 21. I’m guessing they should work, I’ll find out if they are an option when the pre order page is up.
There might be some desire to talk about and learn more about them. And just think, there’s more good stuff to come from Callaway.
?
I think the pros look great. The TCB from the pictures I have seen I am not sure I am a fan.. they are a bit too rounded. Seem even more round than mizuno.. and that is what they are known for.
cant jump to too big of a conclusion off a picture. But so far.. not the biggest fan of that look.
I don’t believe the faces or Ai tech was done any different on the re-tooled combo heads, but I cannot say for certain. What I will say, is that there definitely a different vibe around combo sets than I have ever seen or heard from Callaway. This isn’t just that combo sets are an option, combo sets have moved to the forefront. They are seriously excited to have these in a way that wouldn’t surprise to me find out that there is a lot more that went on with combo sets than we have been told thus far.
We might hit 8 million just from this thread!
But Mizunos are long. These should be a lot more compact. And they look it. Even on TV. I like compact. The X Forged are pretty round, and these sound like a smaller/better X Forged. My only big complaint with the X Forged is the damn offset. Is these are more compact with a little less, I’m in. That size with hollow and tungsten? ? They’ll combo beautifully with the MB’s, or play well on their own.
i understand where you coming from. The x forged do have a smidge too much offset..these couldn’t potentially be better looking in person.
It honestly sounds like they’re the same hollow tech as in the pro’s, just a smaller package.
Don’t think thentagging works here but I was already convinced on a set of MP18’s new or gently used or if adventurous, Sub70 699’s with LW graphite.
I’m on full ponder on 2021 irons. Right now I’m planning on rocking RAZR X-forged with mad scoentist lead tape all around them (placed there when I thought I knew what I was doing).
I think through the years I’ve found what works for me only to have a Sim session like I did today, lol.
Hahaha! These definitely look pretty special!
Most definitely. My brain is just friend on what to get. Plus I’ll just end up playing Jr’s hand Me down MP18’s.
Always good clubs. Thatnks for the review!
I have sleep concerns as well. I shouldn’t have re-read the entire thread at midnight.
The Apex Pro 21 look absolutely stunning. They have so many features I LOVE, and the finish is about perfect! I seriously need to try these.
So finally found some info on this one. This article says they are custom order only. Sounds like it may be a very similar or almost exactly the same version of the X-Forged that is specifically made for blending into Apex sets. Maybe someone else can confirm.

Yeah, the offset on the X Forged 8 iron for example, is rough to look at. Of course, all sins are forgiven if they perform for you though.
I like a big cavity back GI iron as a type of utility iron. They launch higher and have more forgiveness than a typical utility. I feel like they play much better out of the rough too if you find yourself in a long recovery situation. This really depends what you’re using that last long iron spot for though.
Rumour on the street maybe an April release in North America…. time will tell ?.
I had same question, I have sent a note to my Callaway rep, will post when I get a response. Matters when it comes to flex as the MCA site has a fitting chart (swing speed) that aligns to their shaft offerings. Weights just don’t line up.
@JB @Jman do you have any insight on the MMT shaft offering in the ‘21 Apex Pros in that weights don’t line up with the MMT shafts on the MCA site? Thanks.
I looked at this on the Callaway shaft sheet, but it is still the 2020 version of their shaft sheet.
I think my wife might kill me if that happened. I really want these, but just got new irons in the summer of 2019.
They’re Europe only. Vrska mentioned that in this thread.
Facts.
The only thing I can think is the difference is the face. The Apex line has A.I. face tech and the XCB don’t. I cannot imagine they slap the Apex name on it without the benefits or presence of the Apex tech. That just seems odd and not a smart thing to do. Otherwise release TCB when you released XCB.
My current irons only have two rounds on them. Doesn’t change my feelings on it though! I’m weak when it comes to new and shiny. Shafts will be the big question for me.
couple more weeks til preorder. plenty of time to waffle all over the place before landing on a final build.
Apex Pro with the AMT Whites.
I will gladly trade my money with Callaway for that build.
My current set has no rounds on them and I’m debating what shafts i want to test with these before I purchase.
These will last me longer, honey. They’re like a once in a generation release that fits me perfectly. I tried to be excited about my other ones, but they were never quite right for me and it’s been a struggle. I didn’t want to say anything about it because you’re so supportive of me and I didn’t want it to sound like I was complaining. I love you.
This works once.
I need a spare set in case I’m traveling and the current set gets broken or lost. You wouldn’t want me to go travel and break my clubs. I need a backup set!
LMAO if I don’t come back tomorrow you all know what happened to me.
forgiveness is easier than permission. Though it may sting a little more..
Did that on a whim with my driver during my last fitting. However, I am putting a simulator in right now and it may not be the time to push my luck.
haha..
I think it got answered between here and there but @Jman said the TCB is a European only release.
yeah I posted that earlier yesterday then @vgolfman confirmed.
My comment was more along the lines of the TCB face being different from the Xforged, otherwise why release it with the Apex name if it doesnt have the same tech as this line.
