Two independent court tests of the Siux Fenix Pro 2026 agree on almost everything. Exceptional smash power. A firm, hard feel. A racket that punishes sloppy contact. What they do not agree on is the sweet spot, and that disagreement matters more than the twenty points between their ratings.
71 and 91 out of 100: the same racket, twenty points apart
Padel.how tested it and gave 71 out of 100. Padelvergleich, a German test that also played it, gave 91 out of 100. That is a wide gap for one racket.
Read the details and the gap shrinks. Both praise the overhead power. Both warn that off-center hits are punished. The difference is in how harsh they find that punishment. Padel.how calls it a very narrow sweet spot with harsh penalties. It recommends the racket only for advanced left-side attackers with high swing speeds. Padelvergleich calls the sweet spot generous for a diamond, while still saying it demands clean technique. Four video reviews that played it side with padel.how: small sweet spot, demanding, hard to use.
So the rating you experience depends on your contact quality. Hit the center and it is a 91. Miss it and it plays like a 71.
The sweet spot dispute: narrow for one tester, generous for another
Why would two court tests disagree on something so basic? Partly it is calibration: Padelvergleich compares it to other diamonds, and among diamonds it may indeed be forgiving. Padel.how seems to judge it against rackets in general, where a hard diamond with a high balance will always look narrow.
For you the practical answer is simple. If you are coming from a round or teardrop racket, this face will feel small. If you already play a hard diamond, it may feel normal. Either way, expect the ball to die on contact near the frame.
12K carbon over high-density EVA: where the hardness comes from
The construction explains the feel. The faces are 12K carbon over a high-density EVA core, with a carbon frame and a rough surface. Shops list the thickness at 38 mm.
High-density EVA is a hard foam. It returns energy fast and gives a direct, firm impact, but it absorbs very little vibration. Combined with the diamond shape, that is why the comfort meter sits at Low. One video reviewer noted the grip runs thin and needs an overgrip, a cheap fix worth doing.
The rough surface is there for spin on topspin shots and attacking volleys. Siux's product page leans heavily on this, claiming explosive output and easy spin. Treat that as marketing. The tests confirm the power, not the adjectives.
355 to 375 g, diamond, high balance: why the arm pays for the smash
The weight range is 355 to 375 g, and the balance is High, as listed by retailers. No exact balance in millimetres is published.
Head-heavy means mass sits toward the top of the racket. On a smash that mass works for you, adding pace without extra effort. On defense it works against you. The racket is slower to move. Late contact with a hard face sends vibration into the wrist and elbow. One video reviewer called it physically demanding on the arm for exactly this reason. If you have any history of elbow trouble, this profile is a risk, not a detail.
Leo Augsburger plays it on the left: what the pro link tells you
Shops list this as Leo Augsburger's racket. He plays on the left, the attacking side, the player who finishes points. That fits everything the testers found. Padel.how recommends it for advanced left-side players with high swing speeds who win points through overhead play.
Retailers label the level as Professional and the player profile as Power. Do not read that as a requirement, read it as a warning. This racket assumes your technique is already there.
Fenix Pro 2026, Fenix Pro 5 2025 or Joma Hyper Pro HRD: picking your power diamond
Within Siux, the Fenix Pro 5 2025 was listed at Advanced level with 24K carbon faces. The 2026 moves to 12K carbon and a Professional label. Augsburger replaces Álex Chozas as the face of the line. The direct comparison shows the rest stays put: same diamond shape, same 38 mm, same 355 to 375 g.
Outside Siux, the closest rival on paper is the Joma Hyper Pro HRD. Diamond shape, 12K carbon, high balance. Same low control and high power profile. Its weight range is slightly narrower at 360 to 370 g. If the Fenix Pro 2026 tempts you but you want to cross-shop, open the head to head comparison.
