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.

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.”

SIM2 Max and Max OS iron technology

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.

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?

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.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)

McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X

The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.

The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0

The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)

Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X

Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

Fugly as uck but I’m sure there are plenty of mugs out there who believe that genuine innovations are possible every 3 or 4 months. For me though, this is just another example of consumerism at its worse. Next innovation will be a putter that bleeps out any ‘homophobic slurs’ whenever you miss an eight footer.

I agree. Most new irons from the OEMs these days do not look like golf irons. Too many colors and applications. I guess I am getting old and sound more everyday like my grandfather, but I am not looking to play with a piece of equipment that looks more like a Romulan (sp.?) space ship than a golf club. Technology has certainly made great gains, but it can be incorporated while still maintaining a nice clean look if these great technicians put their mind to it.

Now these are genuinely UGLY
I just could not envisage putting these down by the ball or in the bag
