HEAD Extreme Racquets 2026 Review: The Hy-Bor Edition

The HEAD Extreme line has long been the go-to choice for players who want easy access to spin without sacrificing versatility. For 2026, HEAD has rolled out the Hy-Bor edition across the Extreme family - and the consensus from reviewers and play-testers is clear: this is the best Extreme yet.

The updated lineup includes the Extreme MP, Extreme Pro, the all-new Extreme MP XL, plus lighter options in the MP L and MP UL. Every model benefits from HEAD's latest Hy-Bor technology, which weaves boron fibers into the graphite layup for improved stability, better feedback, and a crisper feel on contact.

But don't just take our word for it. We sent the new Extremes out to some of the most trusted voices in tennis equipment reviewing. Here's what they found.

What Is Hy-Bor — and Why Does It Matter?

Before we dive into the reviews, a quick word on the technology driving this update. Hy-Bor adds boron fibers at strategically placed positions around the frame, delivering increased compressional strength that firms up the racquet at the moment of impact — especially at higher swing speeds. Combined with the existing Auxetic construction, spin grommets, and spin shaft, the result is a racquet that feels more connected, more stable, and more responsive than its predecessor.

Every reviewer noticed the difference. But how it translates on court varies by model and playing style — so let's hear from the experts.

Tennis Express: "A Great Racquet for All Levels"

Sam and Susie from Tennis Express put all three main models — the MP, Pro, and the new MP XL — through their paces, and came away impressed across the board.

The Extreme MP was the standout for accessibility. Susie found it excelled everywhere on the court: "Very easy to serve, very easy to get that ball over the net. If you want to put a little bit more power, a little bit more pop, even a slice or kick, it was very easy to just get the point started." From the baseline, she praised its dual nature: "Easy to defend the baseline — if you can get the racquet on the ball, it's going to help you get it over. But if you step in, the ball will run and will escort, too."

Sam highlighted the MP's natural margin-building ability: "Without trying, I'm getting space over the net. I usually live in that area two to four feet over the net, and with just a nice normal motion swing, I'm not putting the net into play at all. And we all hate net errors, right?"

On the Extreme Pro, Susie appreciated the added precision: "With the MP, shots might fly a little too much because it generates a lot of power. With the Pro, you get to be a little bit more precise — on drop shots and all that." Sam positioned it as what he called "a good cheater 98" — a racquet that gives you more go and more muscle than most other 98-square-inch frames, while remaining surprisingly easy to play for its category.

The Extreme MP XL earned strong praise for its serve performance. Susie found it "even easier than the MP and the Pro to serve — you can get that speed and the same effects, the kick, the slice, and it's easy." Sam addressed a common concern about extended-length racquets: "A lot of you players love extended-length models, but sometimes the swing weight is just so darn high it makes them difficult to use. This has a really nice moderate swing weight around 320. It's not like swinging a sledgehammer."

One overarching observation tied the whole lineup together. "These do feel a little bit crisper, a little bit more firm on the flex," Sam noted, "and what that translates to is maybe a little bit more power. But it was predictable — it wasn't like the same swing and the ball goes five feet out." Susie's final word? "I think it's a great racquet for all levels. Anybody could play with this racquet."

Tennis Nerd: "Well Done, HEAD — A Solid Update"

Jonas and Henrik from Tennis Nerd had been critical of the previous Extreme generation, describing it as "very muted" with little connection to the ball. So their reaction to the 2026 update carried extra weight — and it was overwhelmingly positive.

On the Extreme MP, Henrik immediately noticed the Hy-Bor difference: "More solid, more stable in the upper hoop. I'm more connected with the ball. It's a little bit stiffer, not so muted. A good update." Jonas agreed, noting the MP delivers "easy pop" with a "pretty balanced" launch angle — "a little bit higher than Speed, but nothing crazy" — and no unpredictable hot spots in the string bed. He also praised the forgiving sweet spot, calling it "even more so than the Speeds," and noted the racquet plays well even at lower tensions without losing confidence.

The Extreme Pro earned respect as a more effective alternative to the Radical. "It's like a more effective Radical MP," Jonas explained. "If you like the Radical but you want a bit more pop with a smaller head size, this is probably the best one." Henrik added that at 305 grams unstrung versus the Boom Pro's 310, it's a better option for advanced club players who find the Boom Pro a bit much. Both agreed, though, that "for most players, the MP is a safer bet — you need to be a higher-level player to maximize the benefits of the Pro."

But the real excitement was reserved for the Extreme MP XL. "Straight away I was like, this is a great racquet," Jonas said. "Very, very solid — even more solid than the MP. Serves were very good. Slice was really good. Good for two-handed backhand." Henrik was equally taken: "Surprisingly easy to play with and good control. For an extra-long racquet with 100 square inches and a thicker beam, surprisingly good control." The longer handle also provides extra grip room — a welcome bonus for two-handed backhand players who sometimes struggle with shorter grips on other brands. The verdict? "This is the wow racquet of the bunch," Jonas declared. "We discussed — maybe we should switch to this racquet. It's that good. My dad is actually switching to this one after testing a million rackets that he doesn't like."

They also weighed in on how the Extremes compare to the competition. Against Wilson's new P rackets, they found the Extremes "more solid" and "easier to just pick up and play." Against the Babolat Pure Aero, Jonas noted the Aero can feel "metallic and pingy," while the Extreme MP offers "a good mix of being dampened yet still connected with the Hy-Bor."

Their overall assessment? "The things that we were missing on the 2024 version, they fixed for the 2026. Well done, HEAD. Nothing groundbreaking, but a solid update. Nice to see a new model that actually makes some sense in the lineup."

PH Tennis: "For the First Time Ever, We Like All of Them"

Josh and Ben from PH Tennis brought a unique perspective to their review, recalling a conversation with HEAD's head designer about how much Hy-Bor actually goes into each racquet model. The designer wouldn't answer — but PH Tennis suspects the Extreme may contain more than the others, because the difference in feel is far more pronounced here than it was in the Speed or Boom updates.

"The feel has gone from one of quite cushioned and soft and quite juicy power to one of a more connected, sharper, more stable — a better power," Josh explained. Ben elaborated on the stability: "The whole point of Hy-Bor is that as you make contact with the ball, it stiffens everything up. The faster you do that, the greater the effects. And this is more noticeable in the Extreme than in the other rackets."

On the Extreme MP, they emphasized that the racquet rewards commitment. "The Extreme is like the uncle who rides a motorbike — the bad boy of the family. It doesn't quite fit all the others. It's its own thing, and it's wild fun." But they were clear about what it demands: "The faster you go, the better it gets. It really does need to be chucked around. If you want to go fast with this racquet, you have to give it revs." The payoff? "When you do, you can keep it anywhere."

The Extreme Pro surprised them with its spin potential for a 98-square-inch frame: "It's got a tumble dryer in it compared to other 98s. Loads of spin. The racquet just comes alive — why would you play flat with a racquet that can generate spin this well?" They also found it "easy to defend with when you're drilling it — the 98 doesn't seem to matter so much."

PH Tennis was especially enthusiastic about the MP L and MP UL — lighter models that often get overlooked in reviews. "This is something we get asked about a lot — we don't spend enough time on the lighter weights, and these are superb," Ben noted. "For the weight they are, the stability they provide, and the control they provide whilst generating some power is so good." Josh called the MPL "so maneuverable, so easy, but not floppy," adding: "If you're a little bit late, you can just flick it. No pain playing early or late. Huge amounts of spin."

Their broader take on lightweight racquets was emphatic: "The biggest improvement in tennis racquet design in the last 10–15 years is the light ones. If you are a younger junior or an intermediate female player, these MPLs and MPULs are absolutely legitimate options now — maybe for the first time ever." The cosmetic update drew a playful jab — "If only it was slightly more yellow" — but the on-court verdict was unequivocal. "Ultimately, we really like this new Extreme. And maybe for the first time ever, we both like all of them. And that is very rare." Josh summed it up: "Easy, fun, and for the first time feels quality."

Rackets & Runners: "The Best Modern Players' Racquet for Traditional Control"

Luca from Rackets & Runners focused his review on the Extreme Pro, delivering one of the most detailed analyses of how this racquet fits into the competitive landscape alongside the Babolat Pure Aero 98 and Yonex VCORE 98.

His central argument? The Extreme Pro is "the best modern players' racquet for traditional control." While the Aero and VCORE have moved toward modern, non-traditional shapes — higher sweet spots, more leverage, open string beds — the Extreme Pro retains a classic oval hoop, a standard throat, and a string pattern that isn't super open in the sweet spot. "What all this means is that the control is also fairly traditional," Luca explained. "It's a consistent racquet with a medium launch angle, a decent amount of dwell time to grab and place the ball."

This has real implications for players considering a switch. "If you're coming from a Blade or a Radical, this will be the easiest one to transition into the modern players' racquet category," he noted. "You'll gain power and spin, but it's not going to feel weird. It's still going to allow you to use the mechanics you've developed over time."

He went so far as to suggest the Radical may be "almost obsolete" by comparison: "This has equal control, similar feel, and the spin is significantly better — but not required either. You can still play with variety."

On Hy-Bor's impact, Luca described three distinct effects: a satisfying pop as the ball exits the strings, a unique "rubbery spring" sensation that feels like slightly lower tension without losing control, and improved stability on contact. "This is one of the best layup technologies we have right now," he concluded. "There really isn't another one that somehow improves feedback and connection to the ball while also boosting stability."

The trade-off versus the Aero and VCORE? Less raw power and less effortless spin amplification. "Those two rackets feel like cannons. This is much more normal," Luca acknowledged. "But the idea with this Extreme Pro is balance. It doesn't push you into the extreme spin direction. It feels great on spinny shots. It also feels great on flat shots."

He also highlighted the Pro's superiority for touch and finesse: "Volleys, touch shots, and especially slices — this shape does everything finesse-related better. It's not designed purely for the modern baseline game. It's designed for the complete player."

His recommendation was clear: "If you're using a Blade or the Radical, or you're still using a racquet like the Prestige, but you want something with more power and spin, this is the first racquet I would recommend."

Tennis Warehouse: "One of My Favorite Extremes to Date"

The Tennis Warehouse team tested both the Extreme Pro and Extreme MP extensively, stringing them primarily with HEAD Lynx Tour at various tensions.

On the Extreme Pro, play-tester Michelle called it her "favorite Extreme to date," praising its "perfect balance of power with built-in control and access to spin." She loved pulling the trigger on down-the-line shots and found volleys "seamless — so stable up there" with excellent command for both deep and short placements. Manish appreciated the Pro as "one of the most control-oriented power frames I have tested in a while," noting he could go for sharper angles with confidence because "I knew it was still going to go in."

Tiff's experience added nuance: he found the Pro produced a lower trajectory shot compared to the Pure Aero 98 or VCORE, which initially led to overhitting. But once he went up a couple of pounds in tension, "I was totally dialed in — the ball was dipping nicely inside the lines." He particularly enjoyed the slice and doubles net play, calling the blend of stability and maneuverability ideal for fast exchanges. His recommendation: "This is a good option for an intermediate through advanced player who wants to carry a lot of racquet head speed into their shots and get some power from their racquet, but not so much that they're ever going to have to rein it in."

On the Extreme MP, the team noted an immediate improvement over the previous generation. Tiff found no adjustment period this time: "The first time I hit it, I had no issues. Within minutes, I felt like I was rallying well. The control levels were better. I wasn't getting balls flying so high with my flat game." The other tester praised the easy transition and called it "a hidden gem in the HEAD series — might be my favorite HEAD racquet in the lineup right now."

Both testers highlighted the MP's serve performance — "really whippy, easy power, and I was getting into the low 90s without much effort" — and its ability to create sharp angles that pull opponents off the court. The Hy-Bor feel earned universal praise: "Every time HEAD updates a model with Hy-Bor, I really like it. I feel very connected to my shots and it still doesn't feel too stiff."

When compared side by side with the HEAD Boom MP, the Extreme MP "feels like it's got more power and is more stable, where the Boom MP feels more comfortable." Similar specs, but distinctly different personalities.

The Verdict

Across five independent reviews, the message is remarkably consistent: the 2026 HEAD Extreme lineup represents a meaningful step forward. Hy-Bor technology has addressed the biggest criticism of the previous generation — that muted, disconnected feel — while preserving everything that made the Extreme popular: easy spin, accessible power, and genuine versatility.

The Extreme MP remains the heart of the lineup: forgiving, powerful, and suitable for virtually any level. It rewards players who swing with intent and delivers natural margin over the net without asking you to change your game.

The Extreme Pro carves out a unique and important niche as the most controlled option in the modern players' racquet category — ideal for advanced players transitioning from traditional frames who want more spin and power without sacrificing the feel, variety, and finesse they've built their game around.

The Extreme MP XL is the breakout star — a rare extended-length model that delivers tangible benefits in power, stability, and serve performance without the usual drawbacks of excessive swing weight. If you've been curious about longer racquets, this is the one to try.

The Extreme MP L and Extreme MP UL prove that lighter racquets can be legitimate performance tools, not just compromises — opening the door for juniors, developing players, and anyone who values maneuverability.

Expert reviews of the Extreme 2024 tennis racquet series

“The spin was incredible.”

“Very lively – with tonnes of spin.”

“If you’re an aggressive player, you’re going to find a lot to love here.”

Expert reviewers have been testing HEAD’s Extreme 2024 tennis racquet series. At HEAD, we see the Extreme 2024 racquets as the ultimate spin machines - designed for aggressive players who want to spin big and create chaos for opponents – and the reviewers have been enjoying generating huge amounts of spin with these models.

One of the upgrades is the introduction of state-of-the-art Auxetic 2.0 technology for improved stability and a better connection to the ball, giving you a crisp impact feel and maximum spin. The Extreme 2024 series, which is endorsed by Matteo Berrettini, also has a shaft that generates extra spin, along with unique spin grommets that allow for more string movement and a powerful trampoline effect on impact with the ball.

Recommended by the experts

“If you’re prioritizing spin when choosing a racquet, the Extreme series is definitely for you,” said the reviewer for Tennis Mentor, who had the opportunity to test the models while hitting with Wimbledon champion Barbora Krejcikova. “The Extreme is a really good racquet for those who are looking to add more spin or players who already use spin and want to maximize it. Generally, players who are playing on a slower surface like a clay court or a slow hard court are really going to benefit from this type of game style.”

The Tennis Mentor expert felt as though the Auxetic 2.0 Technology “makes for a more comfortable experience”, offering “a subtle but positive difference – it just feels that little bit nicer”. “The racquets have a lovely feel, easy to play with and my shots were landing very deep with little effort. When adding topspin to my strokes, these racquets perform at their best. They’re so good at creating that much-desired arced trajectory... Hitting a kick serve is where I saw the biggest benefit of using the Extreme racquets. I felt the biggest difference in the amount of spin I was getting.”

A reviewer for Tennis Express also recommended the Extreme 2024 series: “It’s incredibly spin-friendly. If you’re looking for a spin-friendly racquet, the Extreme series is a really good option.” Another expert from Tennis Express sounded as though he loved testing the Extreme racquets. “Hitting the sweet spot and really going for the ball was very, very rewarding. The spin was incredible. It seems pretty easy [to attack and get to net], especially with approach shots. Finishing off the points was super nice. This racquet has a really good punch at the net with volleys,” he said. “I was really impressed by how well I was serving with these racquets. It was pretty hard to miss when kicking the ball on your serve.”

“Bright, funky” design

“The new cosmetic pops,” the Tennis Mentor reviewer said of the new, bright and daring design, which includes transparent spin grommets inspired by fashion and sneaker trends.

“If you’re already an Extreme user, you’ll be used to the bright colors but this is another level. If you like bright and funky colors, the 2024 line-up is going to be exciting for you.” A reviewer for Tennis Warehouse said she was “obsessed with the paint job”: “I absolutely love it. So cool to look at.” There was also a positive review from the expert at Tennis Express who said he liked the “bright paint job and the really nice-looking frames”.

Reviews of Extreme PRO 2024

“I really enjoyed hitting with the new Extreme PRO,” said the Racquet Guys reviewer. “I felt as though you could really go after your shots and when you do you get a tonne of spin. That’s what the Extreme racquets are made for – to generate a tonne of spin.” The expert also noted that the racquet felt “extremely solid” when serving or at net and that the Auxetic 2.0 Technology had improved the feel. “Overall, a great frame with tonnes of spin. If you’re an aggressive player, you’re going to find a lot to love here,” according to Racquet Guys.

The reviewer for Tennis Express said the Extreme PRO “felt very precise on serve”.

Reviews of the Extreme MP:

“This is a very lively racquet so tonnes of power and tonnes of spin,” said the reviewer for Tennis Warehouse. “I loved approaching with this racquet because I could drive through the court or pull people off the court with a little bit more spin. And then it felt super solid at net. I could get it nice and deep or even play around with a little touch.” Another expert from Tennis Warehouse said the racquet “felt plusher” while still being “whippy”: “I was able to easily whip my forehand around and get plenty of spin on my shots. I really liked it. Very quick in my hand and easy to execute overheads with.”

Reviews of the Extreme MP:

According to a reviewer from Tennis Warehouse, the feel and the sound of the new Extreme MP “are a bit more solid”.

Hitting with the Extreme MP, the reviewer for Tennis Mentor was generating so much spin that the ball was making more than 3,000 revolutions per minute.

Reviews of the Extreme TOUR

“Lots of easy power, super-manoeuvrable and very fast, which makes it very spin-friendly,” said the reviewer for Tennis Warehouse. “If you're looking to whip an angle, or you've got a low ball and it's kind of short and you're coming in towards the net and you want to get it up and over quickly with lots of spin and pace, the Extreme TOUR racquet is great to do that with. It's a good doubles racquet as it's good on serve and return, and it's nice and fast and easy to move at net. It has a fast feel. It's a very, very quick racquet that feels silky smooth.”

A reviewer for Tennis Spin noted: “The Auxetic technology softens it up and gives you more feel. This racquet is a great update, with easy access to power, a very plush feel. It’s a pretty lively racquet. I like this a lot. Definitely a great, great upgrade.”

Another reviewer for Tennis Spin said: “They’ve added the Auxetic technology and it’s a huge improvement. It makes the racquet a lot softer and a lot more plush. I felt really confident swinging with this racquet. Lots of good control. I was able to swing out as much as I wanted to. I got some pretty good spin on my forehand and backhand. The playability was good.”

Reviews of the Extreme MP

The reviewer for Tennisnerd had “more control and more confidence” to go for his shots. “It's still a powerful racquet and still spin-friendly. I like the design. This is the most improved of the Extreme racquets, with much better control. It's spin-friendly, powerful and not too harsh on the arm, with a denser string pattern for better control. I had a lot of fun with this. It's for you if you're a baseliner and want some power and spin for free, and you play a lot on clay. This will make you happy.”

“A more forgiving and responsive racquet,” said a reviewer for Tennis Warehouse. “One of those racquets when you can really be stretched out wide on defense and with just a flick of the wrist hit a fast-paced ball to the corner and be right back on the offense again. Or even hit winners on the run. It's a fun racquet to do it with. These racquets are so light and manoeuvrable. This is a fun racquet. If you like to hit aggressive groundstrokes with a lot of topspin, you can maximise your [game] with this racquet.”

The reviewer for Solow Sports was able to “push my opponent way back behind the baseline”. “I'm loving the Auxetic technology. The response in feel is just perfect. This racquet is very lively and responsive, which is exactly what's trending for players. You can see why Matteo Berrettini is playing with the Extreme. This is absolutely an enhancement. Players can absolutely command the baseline. HEAD says it's spin for you and chaos for your opponent and we couldn't agree more.”

Reviews of the Extreme TEAM

“A great racquet for the adult who's looking for something super-fast and easy to manoeuvre or for a junior transitioning into an adult-sized frame,” said the reviewer for Tennis Warehouse. “Really good for a mid-level club player. Will get a lot of playability out of this one. Very, very light and fast so easy to get around the body. Silky smooth... with a nice and plush feeling. There's a very nice flex to it so it's very forgiving with a soft response at impact.”

The reviewer for Tennisnerd called this “a really fun racquet to play with”. “I could generate some nice pace and hit some good winners. And it's excellent on defense. This would be a good option for a lot of players. It's a very good frame.”

Review of the Extreme TEAM L

“Very nice feeling on impact. Fun to use. Lots of free pace and spin. But the sensation when you hit the ball is actually quite enjoyable, which is rare for these types of racquets,” observed the reviewer for Tennisnerd. “I enjoyed playing with this a lot. Easy to use, easy to swing. For most players, you get enough stability and power. Perfect for beginners. But this isn't just for beginners; you can use this at an intermediate level. You get some pace and spin that you can really use.”
