Pros

• ✓The 12K carbon and Hard EVA combo delivers a crisp, no-flex response on the smash by 3: the ball comes off flat and low, with barely any energy lost on contact. The diamond shape and high balance pile mass into the head and load extra weight behind the vibora and cut bandeja, where the racket does almost all the work on its own once you're set up. The 38mm frame adds lateral stiffness on off-centre hits toward the upper edge — exactly where you actually make contact on a diamond shape when smashing. The Switch Strap system lets you swap and adjust the wrist strap to your hand, a genuinely useful touch if you're out on court for hours and the grip gets sweaty. At 355 to 375 grams there's room to pick a lighter build within the range and soften the swingweight without losing the attacking racket's character.

Cons

• ✗The Hard EVA core paired with the 12K face gives you short ball exit: defending from the back with the ball hugging the glass, you need a full arm swing because this racket won't hand you depth for free. The high balance hurts your reaction at net when the opponent goes fast at your feet — if you're not set early, the block volley either sails long or dies in the net. The sweet spot is small and sits high on the face: contact low on the frame transmits noticeable vibration and you lose the ball noticeably. With rubber hardness at the top end of the scale, it demands healthy elbow and shoulder — not a racket for back-to-back matches if you're carrying niggles.

The Siux Fenix Pro Black 2026 is designed for competition or pro-level players who prioritise performance and precision over comfort. Its diamond shape moves the sweet spot to the top of the face, giving more leverage and power at the cost of some tolerance. The high balance adds weight to the swing and pushes the racket toward an offensive profile. Its 355-375g weight range places it in the medium-weight group, the most common among amateur players.

Siux Fenix Pro Black 2026 review: Leo Augsburger's 12K diamond racket

The Siux Fenix Pro Black 2026 comes with a 12K carbon face, Hard EVA core, 38mm frame and a weight range of 355 to 375 grams. It's Leo Augsburger's signature racket, and the all-black finish with understated logos makes it the most radical-looking model in the whole Fenix Pro 2026 lineup.

This is not a forgiving padel racket. The spec sheet puts it at the harder end of the catalogue, with a Hard EVA core and a diamond shape, and the on-court behaviour backs that up shot after shot.

Who should actually play with the Fenix Pro Black 2026?

This racket is built for advanced or pro-level players with an attacking style, a seasoned arm and a stable technique on overhead shots. The diamond shape, high balance and Hard EVA core demand a swing speed that an intermediate player simply doesn't generate — and without that speed, the racket turns into dead weight that gives nothing back.

The profile is deliberately narrow. This padel racket isn't chasing the all-court player who mixes defence and attack — it's built for the player who closes out points from the net.

12K carbon over Hard EVA: what that pairing means on contact

The 12K carbon weave on the face gives a rigid surface that barely flexes on impact. In practical terms: the ball doesn't sit on the face, it releases instantly and follows the line your swing gave it — not one the racket decides for you.

Underneath, the Hard EVA core does the same job from the other side. It compresses very little, so almost all the energy you put in comes straight back into the ball instead of getting soaked up in the core. That's what produces the dry, no-bounce response that hard hitters are after.

The trade-off is well known and worth stating plainly: zero help. This racket generates no pace on its own. Whatever comes off it, you put there yourself.

The 38mm frame rounds out the package by adding structural stiffness, particularly useful on hits toward the upper edge of the face — which, on a diamond shape, is where most of your smashes actually land.

Shot by shot: where it shines and where you're on your own

Flat smash and smash by 3. This is the whole sales pitch. The high balance stacks mass in the head and the Hard EVA core doesn't cushion a thing: the flat smash comes off low and fast in a way round-shaped rackets struggle to match. The smash by 3 benefits especially, since the overall stiffness lets you cut the ball with confidence without losing control of the face.

Vibora and bandeja. Head-heavy inertia works in your favour once you're already set under the ball. The vibora comes off loaded with spin and lateral speed; the cut bandeja holds its depth without needing extra arm speed. One condition applies: you need to arrive on time.

Defence and glass exits. The weak point. Ball exit is short and the high balance slows down your manoeuvrability. With the ball dead against the glass, the defensive lob needs a full arm swing and a long follow-through; if you just block it, the ball falls short mid-court and you're handing over the point.

Volleys. Strong on the aggressive finishing volley, where the stiffness helps you nail the ball away. Weaker in fast exchanges at the feet, where the head-heavy balance costs you reaction time and forces you to get set earlier than you're used to.

Sweet spot. Small, and positioned high on the face. Contact below centre is felt immediately — vibration through the hand and a clear loss of pace. That's the structural price of a hard diamond shape, not a manufacturing flaw.

Three things to know before you buy one

1. **It's a racket for a healthy arm.** The hardness sits at the top of the range; with elbow or shoulder issues, this isn't a recommended buy.
2. **The weight range matters.** A 355g build and a 375g build feel like different rackets. If in doubt, start at the lighter end.
3. **You need a partner who defends.** With this racket you're going to attack; if your partner also lives at the net, the gap at the back will show.

The Switch Strap and the case for going all-black

The Switch Strap system lets you customise and swap out the racket's wrist strap. It doesn't change performance, but it does improve ergonomics for anyone putting in long hours on court who needs to dial in the fit to their hand.

As for the finish, the Black version wears an all-black colourway with understated logos. It's the most understated look in the Fenix Pro 2026 range, and for plenty of players that's a real factor in the buying decision.

Verdict: power with no safety net

The Siux Fenix Pro Black 2026 delivers exactly what its spec sheet promises: it turns a fast arm into balls that don't come back. The 12K carbon, Hard EVA core and high balance form a coherent, no-compromise package aimed at competition players who finish points at the net.

If you're after help on ball exit, forgiveness on off-centre hits, or agility in short exchanges, this isn't your racket, and no setup tweak will fix that. But if you've got the technique, the arm, and a game built around the smash, it's one of the most direct options on the market for 2026.
