The Bullpadel Hack 04 is Paquito Navarro’s racket and the flagship power diamond of the Bullpadel range: a TriCarbon 18K face, a MultiEVA core, a high balance of about 264 mm and a 365–375 g weight. Bullpadel says the Hack has been its best-selling line for ten years and the benchmark for raw power, and the 2026 version redefines that as what it calls dynamic power.
The changes are aerodynamic and structural: a Total Channel perimeter, an Air React Channel and the Tricore core. This review covers the build, the specs, how it should play, how it differs from the Hack 04 Comfort and Hybrid and who should buy it, and it lists alternatives because the US listing is often down to a few units.

Our review of the Bullpadel Hack 04
The Hack 04 has the profile you would expect of a power diamond, and Bullpadel’s ratings confirm it: power 4 out of 5 and stiffness 4, with stability, maneuverability, control and sweet spot all at 3. That is a racket that leans on power without giving up everything else, which is a reason the Hack line has sold well for a decade.
The 2026 changes are about speed. The Total Channel perimeter and the Air React Channel are designed to cut air resistance so the head accelerates faster, and the Tricore structure is there to keep the racket from twisting when it is swung hard. Bullpadel describes the result as dynamic power, meaning power that comes from swing speed rather than from sheer stiffness.
We have not played it ourselves, so this is an assessment of Bullpadel’s spec sheet and ratings. On paper it is the most direct power option in the range below the Xplo, and it suits an advanced player with a fast swing.
Pros
- Bullpadel’s best-selling power diamond
- TriCarbon 18K face and a high balance for smashes
- Aerodynamic channels for swing speed
- Custom Weight system for tuning
Cons
- Intermediate to hard feel loads the arm
- Average control and sweet spot ratings
- Bullpadel labels it professional level
- Limited US stock
Who is the Bullpadel Hack 04 for?
The Hack 04 suits advanced players with a fast swing who attack, finish at the net and smash often, and who want a power diamond with a proven track record. It also suits players who find the Xplo too extreme and want power with more balance in the ratings.
Who the Bullpadel Hack 04 is not for
Skip it if you are new to padel, if your arm tires quickly or if you defend from the back of the court. A stiff, head-heavy diamond is demanding, and our intermediate racket guide and tennis elbow guide list easier rackets. The Hack 04 Hybrid is the control-minded version of the same racket.
What to know before you buy the Bullpadel Hack 04
Three versions of the Hack 04
Bullpadel sells the Hack 04 in three forms. The standard racket reviewed here is the power diamond with a TriCarbon 18K face. The Hack 04 Comfort is lighter with a Fibrix face, and the Hack 04 Hybrid is a hybrid shape with an aluminized carbon face and a lower balance. Check the listing title before you order.
Weight and balance
Bullpadel lists 365–375 g with a balance of about 264 mm and a 522 cm² hitting surface. The Custom Weight system lets you shift the balance, and the listing for the Comfort version says by up to 1 cm.
A 2027 version already exists
Bullpadel’s own store lists a Hack 05 for 2027, so the Hack 04 is last season’s racket. A previous-season racket is usually the better value, and the US listing is priced well below the 2027 racket’s list price in Europe.
How the Bullpadel Hack 04 plays
Smashes and the vibora: The high balance, the diamond head and the TriCarbon 18K face are what the racket is built for. Our guides to the kick smash and the vibora cover the technique.
Volleys: The Tricore structure should keep the head stable on hard volleys, though a rating of 3 out of 5 for maneuverability means very quick exchanges are harder than with a lighter racket.
Defense: Not its strength. A stiff diamond with a high balance takes effort to control on the defensive side.
Spin: The 3D Grain surface helps downward shots such as the bandeja and the vibora.
Bullpadel Hack 04 vs the alternatives
Inside Bullpadel, the Xplo is the more extreme power racket, the Vertex 05 is the all-rounder with a larger sweet spot, the Icon is the heavy, dense diamond and the Ionic Power is the cheap route to a diamond. Outside Bullpadel, the Head Extreme Motion and the Nox AT10 Genius Attack are comparable power diamonds. Our best rackets for advanced players guide compares the wider field.
Similar rackets if the Bullpadel Hack 04 sells out
This US listing is often down to a handful of units, so here are the closest alternatives:
- Bullpadel Hack 04 Hybrid: the same racket family with a hybrid shape, a lower balance and more control
- Bullpadel Xplo: the most powerful racket in the range, with a geometric head
- Bullpadel Vertex 05: an all-round diamond with a larger sweet spot
- Head Extreme Motion: a 360 g high-balance diamond with a unidirectional carbon face
Is the Bullpadel Hack 04 worth it?
At about $251 from a third-party seller, the Hack 04 is fair value for an advanced attacker, because Bullpadel’s own store lists the 2026 racket at about 240 euros after a 25% reduction. It is poor value for anyone who needs an easy or forgiving racket.
Conclusion
The Bullpadel Hack 04 is a proven power diamond with a TriCarbon 18K face, a high balance and new aerodynamic channels. Its strengths are power, swing speed and a tunable balance. Its weaknesses are a hard feel, average control and limited stock.
Choose it if you are an advanced attacker with a fast swing. If it is sold out, use the similar rackets above, and browse our best padel rackets roundup for every level.
