Bullpadel Vertex 04 W 2025

Technologies

Pros

• ✓The Custom Weight system takes up to 22g of extra gel or aluminium weights and shifts the balance ±1cm, so you can dial the racket toward an aggressive vibora or a more defensive setup without switching models The sandpaper-style Top Spin surface bites into the ball on the pinchada and on topspin drives from the back of the court: the ball comes off with real rotation, not just pace The 38mm profile with the Carbontube frame and Multieva core gives you a crisp, dry response on the smash por 3 and the flat smash, without the dead bounce you get from softer rubbers The Curvaktiv geometry and Air Power aerodynamic work really show up in swing speed when you're loading up a crosscourt vibora — exactly where this diamond shape earns its keep

Cons

• ✗The mid-to-high balance typical of a diamond shape punishes late preparation: on a low ball off the back glass or a deep lob to your body you need to set up earlier than you would with a round-shaped racket The hard, reactive rubber demands your own technique and rhythm to unlock; hit at half pace and the ball falls short, since the racket won't bail you out on a defensive shot without leg support behind it The sweet spot sits high on the 530 cm² hitting surface, so off-center contact on low volleys sends vibration up the arm and costs you depth Carrying 350-370g match after match takes a toll on the elbow if you don't have the physical conditioning to back it up, especially if you max out the Custom Weight on top of that

Bullpadel Vertex 04 W 2025 review: Delfi Brea's competition diamond

The Bullpadel Vertex 04 W 2025 is a 38mm diamond-shaped padel racket, 350-370g, with a Fibrix face and Multieva core built for a player who closes out points at the net. It's Delfi Brea's racket, the one she's used to climb the Premier Padel world rankings, and its personality leaves no room for doubt: power comes before everything else.

What's new in the Vertex 04 W compared to the previous generation?

Bullpadel puts numbers on the upgrade across four specific areas versus its predecessor: 10% more reactivity, 7.2% more stiffness, 23% better aerodynamics and an 8% bigger sweet spot.

Those figures aren't just marketing filler. The 23% aerodynamic gain translates into a cleaner swing on the vibora and on the smash por 3, where prep time is short. The extra 8% of sweet spot partially offsets what a diamond shape always costs you: forgiveness on off-center hits.

Fibrix, Multieva and Carbontube: what each layer brings to the table

The face blends carbon with fiberglass under Bullpadel's Fibrix label. That mix is the reason this racket doesn't feel like a dead brick: the fiberglass gives back some elasticity on impact, while the carbon keeps the hitting surface rigid.

The Multieva core runs different densities within the same EVA core, and that's the key to how this padel racket behaves depending on where you make contact. Up top — where you're rematando — it responds hard and fast; toward the center it gives a touch more, letting you block volleys without the ball flying off uncontrolled.

The 38mm Carbontube frame, built entirely from carbon, is what keeps the plane stable when you go into a smash with your full bodyweight behind it. Without that frame stiffness, a profile this tall would flex and you'd lose direction on the flat smash.

Vertex Core and Air Power round out the package, working on shock transmission and airflow through the frame. Curvaktiv, meanwhile, is the curved geometry of the upper frame that cuts down resistance as you start your swing.

How it plays on court, shot by shot

On the smash, this is where it earns its place. The combination of the 38mm profile, hard rubber and mid-to-high balance produces a powerful ball exit without having to force your arm. The smash por 3 flies out on a tight trajectory and the kick serve-style bounce is genuinely lively.

On the vibora, the aerodynamic work really shows. The racket gets into the shot fast, and the rough Top Spin surface — that sandpaper-like finish — grips the ball just enough to close out the crosscourt shot with real spin, not just speed.

On the bandeja, it demands clean technique. It's a diamond shape: cut it well and follow through, and the ball lands deep and controlled. Hit a defensive bandeja or arrive a step off position, and the racket won't cover for you.

On defense and off the back glass, this is where you pay the toll. The head-heavy balance forces you to prepare earlier than usual. A low ball skidding off the glass demands a firm wrist and anticipation; prepare late and you'll send back a short ball that hands over the net.

On volleys, it performs better than the shape suggests, thanks to the 530 cm² hitting surface. Even so, off-center contact is noticeable: vibration travels up the arm and depth suffers.

Who is this Bullpadel racket really for?

For competition. This isn't a transitional racket, nor one for an ambitious intermediate player.

The player who gets the most out of it ticks three boxes:

1. **Solid, established technique** on smashes and shots off the back glass, because this racket won't correct execution errors for you.
2. **A trained body**, because 350-370g in a diamond shape over a two-hour match adds up in the shoulder and elbow.
3. **An offensive role on court** — a backhand that steps up to smash, or a forehand that closes out points at the net.

If your game is built around constructing the point from the back, waiting for the opponent's error and playing high lobs, this racket will work against you for the entire match.

The Custom Weight system: a racket you can fine-tune

This Bullpadel model comes with Custom Weight, letting you add up to 22g via gel or aluminium plates and shift the balance point by up to ±1cm.

This is a real feature, not a catalog gimmick. You can start with the factory setup, play ten matches, and then decide you want more head weight for the smash — or less, if you're finding yourself late on defense. Few competition rackets let you adjust balance like this without resorting to badly-placed lead tape at home.

Verdict: power, with a price tag attached

The Vertex 04 W 25 does exactly what it promises. It's a power racket with a generous ball exit, a very rough surface for topspin, and a rigid build that gives back everything you put into it.

What it charges you in return is just as clear: less margin on off-center hits, more demanding prep on defense, and a rubber that falls short at half-intensity.

If you play attacking padel, have a trained shoulder, and want a racket you can fine-tune with Custom Weight as your game evolves, this one fits. If you're after a padel racket that gives you confidence off the back glass and forgives mishit balls, the diamond shape isn't the way to go.
