Bullpadel Vertex 04 vs Hack 04: Which Diamond Racket Should You Pick?

Bullpadel makes two flagship diamond rackets, the Vertex and the Hack, and on paper they look almost identical. Both are diamond shaped, both sit at 365 to 375 g, and both are built for players who like to finish points. After coaching with both frames for several seasons, I can tell you they feel noticeably different. Here is how I explain it to my students.

The short version

• Bullpadel Vertex 04: the more balanced of the two. 12K XT carbon face, rough surface, medium MultiEVA core.
• Bullpadel Hack 04: the more aggressive of the two. Tricarbon face, harder feel, built around the smash.

Face and feel

The Vertex uses a 12K carbon face with a rough, gritty texture. That texture is the main reason the Vertex produces so much spin on kick serves and viboras. Contact feels firm but not punishing.

The Hack uses Bullpadel's Tricarbon layup. It feels stiffer and more explosive. When you catch a smash cleanly it leaves the court fast, but off-center hits on the Hack are less forgiving than on the Vertex.

Balance and handling

Both are high-balance rackets, which means more weight towards the head. In practice the Hack feels a little more head heavy in long net exchanges. If you play a lot of fast volleys at the net, the Vertex is easier on the forearm over a 90-minute match.

Who each racket suits

Pick the Vertex 04 if:

• You want power but still play a lot of controlled shots from the back.
• Spin is a big part of your game.
• You are moving up from a teardrop and want a gentler step into diamonds.

Pick the Hack 04 if:

• You are confident at the net and want to end the point overhead.
• You already play a diamond racket and want more punch.
• You have good technique and do not mind a smaller margin for error.

Hybrid versions

Both lines also come in Hybrid builds with a lower balance and more forgiving feel. They are a smart middle ground for improving players who want the Bullpadel feel without a full diamond's demands. The Bullpadel Vertex page explains the version differences year by year.

My honest take

Most club players I coach end up happier with the Vertex. The Hack is a brilliant racket, but it rewards players who hit the sweet spot consistently. If you are unsure, the Vertex is the safer buy.

What about the 2025 and 2026 models?

The core recipe has not changed much between years. The Hack 04 2026 moves to an 18K Tricarbon face, which adds a bit of feel. The Vertex 04 2025 keeps the 12K XT face. If you find a previous-year model at a good price, it is a sensible buy.

Where to buy

In the US I usually send students to Padelnox, which stocks the current Vertex and Hack range from genuine brand stock. Orders over $99 ship free with tracking, unused rackets can be returned within 30 days, and rackets over $150 include a free overgrip 3-pack and frame protector.

Questions students ask me about the Vertex and Hack

Is the Vertex 04 good for intermediate players? A confident intermediate player can handle it, especially if they already hit with a teardrop. If you are still working on consistency from the back glass, look at the Vertex 04 Hybrid first.

Does the rough face really add spin? Yes. The gritty texture on the Vertex grips the ball for a split second longer, which you notice most on kick serves and viboras. It wears down slowly with play, so expect a little less bite after a long season.

Are the Woman and Comfort versions worth it? The Vertex 04 Woman drops the weight to 345 to 360 g and uses a Fibrix face, which makes it far easier on the arm. The Comfort version uses the same Fibrix idea at 360 to 370 g. Both are excellent if you love the Vertex shape but find the standard version too stiff.

My testing notes

I played both rackets back to back in the same week, switching every set. The Hack won every smash contest. The Vertex won almost everything else: volleys, lobs and long rallies from the back. Over a full match, the Vertex left my forearm noticeably fresher. That is why I keep recommending it as the default choice for strong club players.

Alternatives worth trying

If neither Bullpadel feels right, try the NOX AT10 Genius 18K for a teardrop with Tapia's touch, or read my breakdown of the Babolat Viper family for a different take on the power racket.
