The berimbolo existed before Rafael and Guilherme Mendes. What the brothers did, under Ramon Lemos and later inside their own Costa Mesa academy, was turn a scramble into a system — a de la Riva-fed, back-taking loop reliable enough to decide featherweight World finals against opponents who knew exactly what was coming.
By the middle of the 2010s, a Rafael Mendes featherweight World final had stopped being a mystery. His opponents were the best small grapplers alive, they had studied him on video for years, and they walked out onto the mat in Long Beach knowing the shape of what was coming: Mendes would sit to a de la Riva hook, load his shoulders under their base, and spin — a corkscrewing inversion that fed his hips beneath theirs and hunted the back before they could flatten him out.
They knew it was coming. Most of them lost anyway.
That is the strange fact at the center of the Mendes berimbolo. A signature move that everyone in the division could name, describe, and drill in their own gyms still worked, repeatedly, in the highest-stakes matches the gi tradition produces. The berimbolo was not a secret. It was a system — a sequence of controllable checkpoints, each defended reaction feeding the next, built so that the opponent was never choosing between stopping Mendes and losing, only between which of Mendes's positions to lose from.
The move itself did not belong to Rafael Mendes. Inverted entries from de la Riva existed in Brazilian academies well before him, and the name "berimbolo" was coined by another man entirely. What Rafael and his older brother Guilherme did — under the coach Ramon Lemos, refined daily against each other, and later codified in the room they built in California — was take a low-percentage scramble that flashy purple belts flopped for and turn it into the default attacking language of the lightest weight classes. This is the story of that conversion: how a scramble became a system, and how the system won.
The Mendes berimbolo is the clearest case in modern jiu-jitsu of a move winning at the highest level not because it was new, but because it was systematized — a de la Riva-fed, grip-anchored back-take made so repeatable that opponents could scout it, name it in advance, and still fail to stop it in a World final.
The berimbolo has a genuinely contested origin, and honesty about it is the first requirement of writing about the Mendes version.
The movement — a bottom player inverting under a standing or crouching opponent from the de la Riva guard to spin toward the back or the hips — predates any of its famous exponents. Community history most often credits Samuel Braga with bringing the inversion to prominence, pointing to his use of it from de la Riva at the black-belt World Championship around 2005; Braga himself has said he developed the entry earlier, in his purple-belt years, and some accounts push a version of the movement back further still to the 1990s. The word "berimbolo" is a later addition and a separate act: it was , the Atos founder, who is credited with naming the position, borrowing a Brazilian-Portuguese term for a tangle or scramble. Braga made it a technique; Galvão gave it a name. Neither man is the reason it became the featherweight blueprint.
That reason is the Mendes brothers, and the attribution has to be made precisely, because it is easy to overstate. Rafael Mendes — born 20 June 1989 in Rio Claro, São Paulo — and his older brother Guilherme trained from childhood under Ramon Lemos, the coach whose competition program grew into Atos Jiu-Jitsu. Lemos promoted Rafael to black belt around 2009 (some accounts date the brothers' promotions to 2008; the exact year is flagged below). The two brothers were a single laboratory: one weight range apart, trained by the same coach, pressure-testing the same bottom game against each other every day. When the sport talks about "the Mendes berimbolo," it is describing a movement Lemos coached, the brothers refined in the room, and Rafael executed on the biggest stages the gi has.
What the brothers added was not the spin. It was the surrounding architecture that made the spin safe to gamble a World final on. Through the period roughly spanning 2009 to 2012, Rafael and Guilherme used the berimbolo relentlessly enough, and in high-profile-enough matches, that the wider community came to associate the position with them specifically — not as a highlight-reel curiosity but as a scoring, back-taking, match-winning offense against elite black belts. The move became "the Mendes movement" because they made it win at the level where low-percentage techniques get exposed.
The codification followed the competitive proof, which is the correct order for a real system. After the brothers opened the Art of Jiu Jitsu Academy — AOJ — in Costa Mesa, California in 2012 (with RVCA founder PM Tenore; initially an Atos affiliate, fully independent by 2020), they published their bottom game as a teachable method rather than a personal trick. The brothers' de la Riva, berimbolo, and 50/50 instructional material — including berimbolo-specific breakdowns released under the Mendes/AOJ banner — is the paper trail that lets this desk call the position a system and not a signature. When the world's featherweights could buy the exact sequence and still lose to it, the systematization was complete.
The parent of this article is the generic berimbolo — a page that describes a movement: how to invert from de la Riva and spin toward the back. The Mendes system describes something a technique page cannot. It is not the spin. It is the ordered method that makes the spin a high-percentage back-take at black belt: the entry that loads it, the grips that survive it, the checkpoints that catch it when it stalls, and the decision tree that converts every one of the opponent's defenses into another attack. Four principles hold it together.
1. The de la Riva guard is the entry, not a resting place.
The Mendes berimbolo does not begin with the spin. It begins with a controlling de la Riva hook — the outside hook behind the standing opponent's near leg — anchored by a sleeve grip and a grip on the far ankle or pant cuff. This is the load-bearing detail the highlight clips omit. The hook behind the leg does two jobs at once: it off-balances the passer, tipping his weight backward and onto the leg Mendes controls, and it pre-loads the rotation, orienting the opponent's base so that the inversion travels under him rather than away from him. A berimbolo attempted without that de la Riva control is the low-percentage scramble the sport spent years dismissing. Build the guard first; the spin is the reward, not the entry.
2. The grips outlive the rotation.
The inversion is only a back-take if the grips survive it; otherwise it is a coin-flip scramble. The single most repeated failure among practitioners chasing the Mendes game is releasing the sleeve or the cuff to "commit" to the spin — which hands the opponent a free frame to post, flatten, and step over the top. In the Mendes version, the sleeve and pant-cuff grips are held through the rotation, so that at the moment Mendes arrives underneath, the opponent's leg is already trapped and his posting hand is already occupied. The grips are what make the movement a back-take instead of a gamble. This is why the system rewards patience over acrobatics: the spin can be slow, so long as the grips never break.
3. The back-take is a hip-height problem, not an upside-down one.
The purpose of the inversion is to deliver Mendes's hips beneath the opponent's, from where he can come up on the far side and climb to back control. The defining moment is not the somersault; it is the instant he stops rotating and drives his near hip up and across, threading a first hook and lifting into the back. Against a defender who tries to "run the hips" — spinning away to deny the back — the system's answer is the crab-ride and twister-hook family of controls that keep the opponent's hips pinned to Mendes's while he finishes the climb. The endgame is the same one every serious guard ultimately points at: back control, two hooks and a harness, the highest-value position in the sport. The berimbolo is not the finish. It is the most reliable on-ramp the featherweight game has to the finish.
4. Every defense feeds the next position — the loop closes.
The reason a scouted move keeps working is that it is not one move. When the opponent defends the back by rotating with Mendes, he arrives in the 50/50 guard — the symmetric leg entanglement where both players triangle one leg around the other's — and in the rule set of the era, 50/50 was a control-and-sweep position Mendes used to grind out and reverse defenders who had otherwise denied his back-take. When the opponent instead orients his entire defense toward stopping the spin and the back-take, he exposes the counter Rafael Mendes built on the top side: the leg drag, treated in depth in Rafael Mendes's leg-drag system, which punishes the exact defensive posture the berimbolo forces. That top-game punctuation is a companion article's subject, but it is load-bearing here for one reason: it is what makes the berimbolo unlosable to defend correctly. Stop the back-take and concede the pass; defend the pass and concede the back. The opponent is not choosing between good and bad options. He is choosing which of Mendes's positions to lose from.
What a section of the generic berimbolo page could never say is this: in Mendes's hands the inversion is not a technique you attempt — it is the engine of a closed loop that begins in de la Riva, threatens the back, and routes every defensive reaction into 50/50 or into a leg-drag pass, so that the same spin an opponent has drilled for years still delivers him, in a World final, to a position he chose only in the sense that Mendes let him.
The Mendes berimbolo occupies an unusual place in 2026: it is simultaneously everywhere and, at the very top, less visible than it was. Both facts are true, and together they describe what real influence looks like.
The everywhere part is the more important. In the early 2010s the berimbolo was a genuine competitive edge — a movement most opponents could not stop because most opponents had not yet been forced to learn it. By the 2020s it had been so completely absorbed into the sport that it is now standard curriculum, taught to blue belts as a matter of course, with a decade of accumulated counters available to any passer who wants them. That is not the move fading. That is the signature of a technique that changed the sport: everyone now defends it, which means everyone once had to learn to defend it, and they learned because of what the brothers did with it in finals.
The two clearest tributaries downstream of the Mendes version run in different directions. The first is the Miyao brothers — João and Paulo — who broke out roughly in 2011–2012 and modernized the position for the lightest divisions, leaning heavily on the crab ride and the twister hook to push the berimbolo toward a relentless, high-volume, back-taking grind. The Miyaos have publicly credited the Mendes brothers as a major influence on their game; their version is a sibling of the Mendes system, not a rival origin — the same engine tuned for a different, more berimbolo-centric competitive identity. The second tributary runs through AOJ's own room: the academy became one of the most productive competition gyms in the world, and its junior products absorbed the de la Riva-and-back-take game as a native language rather than an imported set of techniques, most visibly Tainan Dalpra, whose point-starving World-title runs read as a direct inheritance of his coaches' method.
At the very highest weight-and-skill classes the berimbolo is used more sparingly, which is often misread as decline. Elite modern grapplers have both the counters and the athletic tools to bypass a scouted inversion, and the flashier no-gi, submission-only, big-money scene of 2026 rewards leg entanglements and finishing sequences over the patient gi back-take the berimbolo was built for. But the Mendes berimbolo was always a gi system — grip-dependent, positional, decided on control — and its continued place in the curriculum of nearly every serious academy is the quiet argument that it is not a relic of a slower era but part of the substructure the modern game is built on top of.
The Mendes berimbolo's competitive record is inseparable from Rafael Mendes's rivalry with Rubens "Cobrinha" Charles, the featherweight standard-bearer he displaced. The two met well over a dozen times across gi and no-gi between 2008 and 2015; public tallies of the exact head-to-head differ, but Mendes finished with the clear edge in the matches that mattered most, and the bottom game — de la Riva to berimbolo to 50/50 — was the through-line of those meetings. Scores and dates below are stated only where this desk is confident; the rest are flagged for source-check.
The overall shape is unambiguous: across the defining decade of featherweight jiu-jitsu, the biggest matches were Mendes versus Cobrinha, and Mendes won most of them — including the ones that set records — on the back of a bottom game the berimbolo powered.
White belt meets the berimbolo as a party trick — the spin a purple belt uses to take your back before you understand what happened. The lesson at this rank is not to copy the spin. It is to learn the de la Riva hook and the sleeve-and-cuff grips that make the spin possible, because you cannot berimbolo from a de la Riva you cannot hold. Earn the entry first.
Blue belt drills the rotation and immediately discovers the gap between the highlight and the live rep. The inversion that looks effortless in a Mendes final requires grips that survive the opponent's first reaction. The blue belt's whole job is grip retention through the spin: a berimbolo that loses its grips is a failed rep, even when it ends on top.
Purple belt learns the back half of the system — what to do when the spin does not immediately yield the back. This is where 50/50, the recovery to a sweep, and the climb from the crab ride enter. The purple belt stops thinking of the berimbolo as a move and starts seeing it as a decision tree whose branches matter more than its trunk.
Brown belt connects the bottom game to its top-game counter, learning the leg drag that punishes an opponent over-committed to stopping the back-take. At this rank the loop becomes visible: the bottom game and the top game are the same system seen from opposite sides.
Black belt rebuilds the whole thing against opponents who know it cold. This is the actual Mendes problem — how to win with a system your opponent has studied on video for years — and the answer is layering, disguise, and the patience to make the opponent choose which of your positions to lose from. That is roughly the project that took the featherweight division a decade to solve.
1. Spinning without the de la Riva foundation. The most common error among practitioners chasing the Mendes game. The berimbolo is the back half of a sequence that starts with a controlling de la Riva hook and grips. Inverting without that control just donates your back and your legs to the opponent. Build the guard first; the rotation is the reward.
2. Releasing the grips to commit to the spin. The inversion is only safe if the sleeve and cuff grips survive it. Practitioners who let go to "throw" the berimbolo hand the opponent a free frame to flatten or step over. Hold the grips through the rotation, always.
3. Chasing the somersault instead of the hip. The berimbolo is not judged on how completely you invert; it is judged on whether your hips arrive beneath the opponent's. Rolling all the way through without driving the near hip up and across produces a spin that ends where it started. Aim the hips, not the head.
4. Treating 50/50 as a resting place. When the back-take stalls into 50/50, the entanglement is an active control that must lead somewhere — a sweep, a back-take, a reversal. Sitting in it with no plan converts a winning position into a stalled, penalized one. Every second in 50/50 should point at an exit.
5. Copying the flash and skipping the loop. People drill the visible spin and ignore the leg-drag counter and the grip-fighting that set it up, then wonder why elite opponents shut their back-take down. The berimbolo without its top-game punctuation is a system missing its second half — exactly the half that makes it unlosable to defend.
At open mat this week, build the system in the order it was built, one layer per round, and refuse to skip ahead.
Round one — earn the entry. Start seated in a de la Riva guard against a standing partner. Your only job for fifteen minutes is to retain the outside hook and the sleeve-and-cuff grips while your partner tries to strip them and pass. No berimbolo yet. You will lose the grips, then lose them more slowly, then hold them. That is the foundation almost everyone skips.
Round two — train the grips, not the acrobatics. From the de la Riva you held in round one, drill the berimbolo spin to the back-take, but reset the instant a grip breaks. The rule is strict: a berimbolo that loses control is a failed rep even if you end up on top. You are rehearsing the grips that make the spin a back-take.
Round three — close the loop. Have your partner defend by running the hips to deny the back, and use that exact rotation either to settle into a 50/50 you immediately attack from, or to enter a leg-drag pass. This is the piece that makes the system whole: the defense to one attack is the entry to the next. Six weeks of this order — entry, grips, loop — and the pieces connect the way they were designed to.
The Mendes berimbolo is the hinge between the guards of the 2000s and the systems of the 2010s — the point where a scramble became a repeatable back-take engine.
The map's logic is that the berimbolo is not a destination but a router: de la Riva loads it, back control is where it wants to arrive, and the leg drag is what happens to opponents who defend the arrival too well. Rafael Mendes is the name at the center because he is the one who wired the router together and then proved it in finals.
