Bullpadel Hack 04 Hybrid 25

The name says Hybrid, the balance says High, and the 2026 racket changes the shape to Diamond and the balance to Low. That is the useful thing to know before anything else about this racket.

The Hack 04 Hybrid 25 is Paquito Navarro's racket in the Bullpadel range. It is listed at professional level. No review has been found yet, so everything below comes from the specs.

Hybrid and High here, Diamond and Low in 2026: what the successor reversed

The 2026 Hack 04 Hybrid 26 changes quite a lot. The shape goes from Hybrid to Diamond. The balance goes from High to Low. The face moves from 3D Tricarbon to Tricarbon 18K, and the frame is listed differently.

What stays the same: MultiEVA core, 38 mm thickness, and 365 to 375 g. The shape and balance changes are significant, even though the name looks similar.

Hack 04 Hybrid or plain Hack 04: same year, different head

There is also a Hack 04 2025. It is a Diamond with a Tricarbon face, and the same High balance and weight range. Its control meter is Low, against Medium here.

So the Hybrid in the name matters. This one has the higher control meter of the two. Power stays High on both, and comfort and sweet spot are Low on both.

365 to 375 g with a high balance: what a professional-level arm has to carry

The weight range is 365 to 375 g, and the racket uses a Custom Weight system. Balance is listed as High, with no millimetre figure. That means the weight sits towards the head.

On court that usually gives you easy power. It also asks more of your shoulder and elbow. Not a racket to pick up after a long break. The 2026 version has a Low balance, so it is a different setup, but its comfort is not rated here.

Control Medium, power High: how 3D Tricarbon and a hybrid head get there

The core is MultiEVA, the face is 3D Tricarbon and the frame is listed as 100% bi-directional interlocking carbon. The meters read the core, face and shape as helping control. The high balance holds control at Medium.

Power reaches High because the face, the shape, the weight and the balance all point the same way. Comfort and maneuverability are both Low, for the same weight and balance reasons. That is the trade-off for the power.

Power and control in balance, says the product page: where the claim and the meters part

The product page claims a balance between power and control. Bullpadel's own ratings, as found through a search, give Power 2, Stability 2, Maneuverability 4, Control 4, Sweet spot size 4 and Stiffness 3. Those look quite different from the meters here, which put power at High and maneuverability at Low.

The two sources disagree. The brand ratings came from a search, so use them with care. The reading of the specs on this page is the more cautious one.

Not published: head size, balance in mm, handle, and any court test

Head size is not published. Balance in millimetres is not published. The handle is not published either. That matters because head size would say a lot about the sweet spot, which the meters call Low.

No reviewer has played this version in the sources found. Until one does, you are reading specs, not court results. If you can, try it before you commit.

For a racket with Medium power and Medium comfort, look at the Bullpadel Xplo 02 27. It is also listed at professional level, with a High balance and the same 365 to 375 g, but its face is X Tend Carbon 3K.
