Siux Fenix Pro 5 2025
The Fenix Pro 5 2025 is Siux’s designated “finisher” racket: a hexagonal diamond shape, head-heavy balance and hard touch built purely to maximise hitting power.
It is the racket Leo Augsburger takes on tour, and it shows. Everything about it, from the 24K carbon faces to the hard EVA core and the weight sitting high in the head, is tuned for one job: making the ball leave the glass as fast as possible. It is honest about that, and so should you be before buying it.
Pros & Cons
Pros
- Hexagonal diamond geometry maximises hitting power.
- 24K carbon faces add durability and a premium feel.
- Hard EVA core delivers firm, precise contact.
- Rough surface generates real spin on aggressive shots.
Cons
- Stiffness makes it unsuitable for beginners or intermediates.
- Requires real technical mastery and physical strength.
- Not forgiving on off-centre hits.
On-court performance
Back of the court
This is not the Fenix Pro 5’s strength — the head-heavy, hard-feel design asks a lot of technique to control from deep.
From deep, it asks you to commit. Full, early swings send the ball through with real weight, but defensive blocks and late lobs are harder to place than with a round or teardrop racket. Players who defend with patience will find it tiring; players who use the back of the court to prepare an attack will feel at home.
At the net
Aggressive volleys and finishing shots at close range are where this racket wants to operate.
The high balance gives volleys real punch: a firm block at the net carries weight without a big swing. The trade-off is speed in rapid exchanges, where the head-heavy feel can make you a fraction late. Keep the racket up and in front, and it rewards you.
Overheads (bandeja, víbora, smash)
This is the racket’s entire purpose: elite finishing power on smashes for players who control the net.
Flat smashes and x3s are where the hard EVA and 24K faces pay off: the ball comes off fast and stays heavy. Víboras and bandejas work too, but they feel more like attacking shots than holding shots. If your overhead is your weapon, this racket makes it louder.
Comfort & vibrations
Firm and demanding — the hard EVA core prioritises power transfer over comfort, so sensitive arms will feel it.
Comfort is the price of the power. The hard core transmits more vibration than softer rackets, especially on off-centre hits. If you are prone to elbow or shoulder trouble, this is not the racket to experiment with.
Spin
The rough 3D finish on the faces grips the ball well on kick smashes and cut víboras. Spin here is a tool for finishing points, not for slowing the game down.
Who it’s for / who should skip it
Good fit if…
- You’re an advanced player who relies on power, speed and precision.
- You control the net and finish points aggressively.
- You have the physical strength and technique to exploit a stiff, hard-feel diamond.
Skip it if…
- You’re a beginner or intermediate player.
- You need forgiveness on off-centre hits.
- You play primarily from the back of the court.
Built around Leo Augsburger’s game
Leo Augsburger is known on the professional tour for some of the most powerful overheads in the game, and the Fenix Pro 5 is built to match. Siux did not try to make it versatile; it chose a clear identity: hard core, high balance, stiff 24K faces.
That makes it a great choice for a narrow group of players and a poor one for everyone else. If you are an advanced, physically strong player who already wins points overhead, it adds pace. If you are still building consistency, a hybrid such as the Siux Diablo Pro 4 will win you more matches.

Verdict
The Fenix Pro 5 2025 is exactly what its “finisher” nickname suggests: a hexagonal diamond built purely to end points with power, at the cost of forgiveness everywhere else.
It’s not a racket for developing players, but for advanced, physically strong players who dominate at the net, few rackets in Siux’s range hit harder.
Buy it for what it is: a specialist. In the right hands it is one of the hardest-hitting rackets Siux makes; in the wrong hands it turns small errors into lost points.
