Siux Padel Rackets

Siux is a Spanish padel brand founded in Madrid in 2009, at the point where the sport was turning from a club pastime into a professional tour. The founders came from the players' side rather than the factory side, and that shows in the catalogue: Siux has always built rackets around a feel rather than a spec sheet, and it has signed players who hit hard and talk straight. Franco Stupaczuk, the Argentine who has spent years in the world top ten, plays the Electra and has his initials on the ST4. Before him the brand built its name with Sanyo Gutiérrez and a run of attacking players whose rackets sold because people saw them used at the sharp end.

Siux UK availability came later than Bullpadel and Head, which is why you will still see fewer of them on club racks. That is changing. Siux padel is now one of the brand names new players search for, partly because the Electra is on television every week and partly because the rackets sit at a price where a second-season player can afford one. We stock Siux because the frames are consistent, the warranty is handled properly through the UK wholesaler, and the three main lines map cleanly onto the three kinds of player who walk into a padel shop.

If you want the short version: Trilogy for control, Pegasus for an all-round game with power on tap, Electra for attackers who have the timing to use a hybrid head. The rest of this page is the long version.

Siux organises its range by line, and each line carries a shape, a balance and a character. Within a line the models step up in face material and price, so an Electra ST4 Pro and an Electra GO 3 share a silhouette but not a feel. Here is what each line is for.

Electra is the attacking line and the one most people mean when they say Siux. The current model is the Electra ST4 Pro, a hybrid between teardrop and diamond with the weight carried high, an 18K carbon face and a medium-firm core. It is the racket Stupaczuk plays and it behaves like it: fast through the air, brutal on a smash when you connect, less forgiving on a late volley.

Pegasus is the power teardrop, and its flagship Pegasus Pro is the hard 12K version. The Pegasus Elite 4 carries a 3K carbon face over a firm EVA Pro core, with the balance sitting in the middle of the frame. It is the Siux most intermediate players should look at first, because it gives you a real attacking shot without the small sweet spot of a diamond.

Trilogy is the control line and the softest in the range. The Trilogy Elite 6 is a round racket with a low balance, a soft EVA core and a fibreglass-carbon mix on the face, so it flexes on contact and hands the ball back with very little effort. It is the right first Siux and the right Siux for anyone whose game is built on lobs, placement and not missing.

Diablo sits between Pegasus and Electra: a teardrop with a medium balance and a harder feel than the Pegasus, aimed at all-rounders who lean towards attack. Spartan is the value line, a round or teardrop frame with a fibreglass face at a lower price, and it is the one to look at if you want the brand without the pro price. We list the lines we can get; if a model you want is missing, email us and we can usually get it from the wholesaler within a week.

The honest way to choose a Siux is to be honest about how you play now, not how you want to play next year. A racket that is one step ahead of your game will teach you something; one that is three steps ahead will frame every mistimed ball and take the fun out of your Tuesday night.

If you have played fewer than thirty sessions, or you are the player on court who wins by not missing, buy the Trilogy Elite 6. If you have a reliable volley, you are starting to smash with intent and you want a racket that will not hold you back for two seasons, buy the Pegasus Elite 4. If you already play from the net, your smash finishes points and you have tried a diamond and liked it, buy the Electra ST4 Pro. If you are buying for a child or a teenager, look at the junior rackets instead; Siux makes junior frames but the Bullpadel junior range is lighter.

Players coming from tennis tend to over-buy. A good tennis player has the swing speed for an Electra but not yet the padel timing, and the result is a racket that sends the ball long until the technique catches up. Start with the Pegasus and move up when the smash stops going out.

The Siux Electra is the racket that made the brand in the UK, and the ST4 Pro is the 2026 version. It is a hybrid shape, closer to a diamond than a teardrop, with an 18K carbon face, a medium-firm EVA core and a balance that sits high. Weight runs 360 to 375g. What that adds up to on court is a frame that swings fast for its weight, connects with a crack on the smash and sends a bandeja deep with almost no effort.

The flip side is a sweet spot that is small and high. Hit the ball an inch low on the face and the response is dull and short. Defensive lobs off the back glass need a committed swing because the head wants to be in front of you, not behind. If you play from the net and your opponents fear your smash, this is the Siux to buy. If you spend most points at the back wall, it is the wrong one and no amount of brand loyalty will change that.

The ST4 Pro is the Siux most often bought as a second racket by players moving from a round frame. It is also the one most often returned by players who bought it for the colour. Try the advanced padel rackets page for the frames it competes with, including the Bullpadel Vertex 04 and the Varlion Bourne Summum.

The Pegasus Elite 4 is the Siux we recommend most. It is a teardrop with a 12K carbon face and a firmer core than the Trilogy, balanced in the middle of the frame at around 365g. That combination gives you a smash that finishes points when you commit to it and a volley that stays stable when you do not. It is not as soft as a round racket, so a very new player will notice a little more vibration, but anyone with a season behind them will find it easy to live with. Players who are at the stage of wanting to attack without giving up control should look here before anywhere else, and the intermediate rackets page shows how it compares with the Bullpadel Flow and Volt 900.

The Trilogy Elite 6 is a different animal. Round, low-balanced, soft-cored, with a fibreglass-and-carbon face that flexes on contact, it is built to make the ball easy. Lobs go deep without being muscled, volleys go where you point them, and a mistimed ball still comes back over the net. It will not smash through a good defence, but it will not make you lose points either, and that is why it is the right first Siux. It is also the Siux that club coaches recommend to adults learning the sport, because it lets them learn the sport rather than fight the racket.

Between the two, the question is simple: are you still learning to not miss, or are you learning to finish? Trilogy for the first, Pegasus for the second.

Every Siux padel racket is a foam core between two fibre faces inside a carbon frame, like every other serious padel racket. The differences are in the density of the foam, the weave of the carbon and how the two are bonded, and those differences are what you feel.

Siux uses EVA foam cores in three densities. The Trilogy uses a soft EVA that compresses easily and gives you rebound without effort. The Pegasus and Diablo use a medium to firm EVA that compresses less, so the ball leaves the face faster but you have to hit it to make that happen. The Electra uses a medium-firm EVA tuned for a fast rebound on the smash. None of the current range uses a FOAM-type polyethylene core, which is softer and ages faster.

The faces are where the price goes. Fibreglass on the Spartan and the Trilogy flexes and forgives. 12K carbon on the Pegasus and Diablo is stiffer, holds its shape longer and gives a cleaner response. 18K carbon on the Electra is stiffer again and is the weave you see on the rackets at the top of the tour. Siux also finishes most faces with a rough textured coating that grips the ball for spin on the bandeja and vibora; it wears down with heavy use and is part of why a Siux feels different after a season.

Frames are 100 percent carbon across the range, with the usual edge protector on the top of the head. Siux rackets are 45.5cm long and 26cm wide at most, as the rules require, and every one ships with a wrist cord fitted. Grip size is standard across the range, so if you have large hands plan on one overgrip straight away.

The three brands we stock most are the three a UK buyer is most likely to be choosing between, so here is the honest comparison. Bullpadel is the biggest brand in the sport, with the deepest catalogue and the most consistent factory output; a Vertex or Hack is the safest advanced buy because you know exactly what you are getting and the resale value holds. Varlion is the oldest of the three and the most technical, with unusual shapes like the Bourne and a reputation for control frames that advanced defenders love. Siux sits between them: a smaller catalogue than Bullpadel, a livelier feel than Varlion, and a price point about 10 to 15 percent under the Bullpadel equivalent at each level.

Feel is the real difference. A Bullpadel Vertex feels dense and precise. A Varlion Bourne feels controlled and almost dampened. A Siux Electra feels quick and slightly raw, which some players love and others find twitchy. If you can, hit with all three. If you cannot, the lines on this page tell you which Siux maps onto the Bullpadel or Varlion you have been eyeing: Trilogy against the Bullpadel Flow, Pegasus against the Neuron, Electra against the Vertex 04.

Every Siux racket we sell comes through The Padel Company, a UK wholesaler that has supplied Siux to British clubs and shops since the brand first arrived here. That matters for three reasons. The rackets are genuine current-season stock, not parallel imports with an unknown history. The manufacturer warranty against frame cracking from normal play is honoured through the wholesaler, with the racket inspected in the UK rather than posted to Spain. And the prices are set for the UK market, so you are not paying Spanish retail plus courier plus a surprise import charge at the door.

A Siux order arrives in 3 to 4 working days on a tracked service, free on orders over £40. Full details are on the delivery page. If it is not the right racket, you have 30 days to return it unused with the frame film intact; the returns page explains how. Frames that crack in normal play within the warranty period go back through us to the wholesaler.

One thing to know about Siux specifically: the brand refreshes colours every season and the previous colour drops in price when it does. The racket underneath is usually identical. If you are not fussy about the paint, last season's Pegasus is one of the best-value padel rackets in the country.

Siux makes a full line of padel bags, and the Tour backpack is the one we stock because it carries two rackets, a change of kit and a tube of balls without looking like you are going camping. The thermal racket pocket is worth having if you leave the bag in the car, because a cold core plays dead for the first twenty minutes. See the full range on the padel bags page.

Siux shoes are built on a clay-court pattern with a herringbone sole, which is what you want on an artificial-grass padel court. They run slightly narrow, so if you are between sizes go up. We carry a short range of Siux footwear alongside the Bullpadel, adidas and ASICS pairs on the padel shoes page.

Overgrips, wrist cords and edge protectors are the three accessories every Siux owner ends up buying. The rough face does not need protecting, but the top edge does; a fresh protector costs a few pounds and stops the first glass scrape from becoming a crack.

A Siux will last three to five seasons if you treat it well and one if you do not. The core is foam and the face is resin and fibre; both hate heat, so never leave the racket in a car in summer and never dry it on a radiator. Store it in a thermal bag between sessions. Replace the edge protector as soon as it wears through, because the frame edge is the one place a Siux can crack from a wall strike. Change the overgrip every four to six weeks of regular play, or when it goes shiny, because a slipping grip is how wrist cords get tested.

If the face starts to feel dead, that is the core settling and it is normal after a season or two of hard play. It is not a warranty issue and it is not fixable; it is the point at which most players move up a line, which is how a Trilogy owner ends up with a Pegasus.

Siux names its rackets in layers and the UK searches reflect it: siux st4, siux stupa, siux diablo pro 4, siux fenix pro 5, siux pegasus pro. Pro is the flagship tier, a 12K, 16K or 24K carbon face on the family mould. Elite is the 3K carbon version of the same mould at roughly two-thirds of the price. Astra is the intermediate line and Beat the beginner one. The families each have a character: Electra (Franco Stupaczuk, hence Stupa; teardrop, hard), Diablo (teardrop, 24K TeXtreme face, medium feel), Fenix (Leo Augsburger; diamond, the hardest racket Siux makes, 10 out of 10 on its own feel scale, and the subject of our Siux Fenix Pro page), Pegasus (teardrop power), Valkiria (Sofia Araujo, 340 to 360 g) and Trilogy (round control), which the 2027 range replaces with the new Obsidian control mould.

The Fenix family also has a gentler teardrop, the 2024 Fenix Go 4, which is not a diamond. For a value carbon racket, the 3K Evoque 3K is a teardrop aimed at beginners and intermediates, though nobody has tested it independently yet, and the near-identical Zyron 3K is its twin. The older Spyder Lite line is a round control option too, in the 2024 Spyder Lite Ctrl 3 Hard. The older fibreglass Optimus line is still around too: the Optimus 5 is a soft, durable racket rather than a carbon performance frame, and the lighter Optimus 5 Air drops 15 g for quicker hands. The numbers changed in 2026, which is why old and new listings look inconsistent. Until 2025 Siux numbered the generations: Diablo Pro 4, Fenix Pro 5, Electra ST4 (the fourth Stupaczuk edition), Trilogy Pro 5. The 2026 collection switched to the season year plus a colour name, so the Electra ST4 became the Electra Pro 2026 Fire Red or Shadow Red. The 2027 collection, published on 21 October 2026, uses the year only. A racket sold as "ST3" is the 2024 Electra (see the Electra ST3 Stupa Pro and the softer Electra ST3 Go); a racket sold as "ST4" is the 2025 Electra; a racket sold as "Electra Pro 26" is the same line a year on. Siux rackets UK buyers see in the shops sit at about £170 for the Electra Pro 26 (sold as Fire Red or Shadow Red), £200 for the Diablo Pro 26, £180 for the Fenix Pro 26 and £245 for the Trilogy Pro 26 (its 2025 predecessor is the Trilogy Pro 5); the Electra Flow 4 is the Electra to read about with care, because no independent test exists.

Two honest cautions from the testers. The Pro tier is hard and dry, with the Electra described as "demanding, not forgiving", so it suits a player who already strikes cleanly; if you want comfort, the Elite tier or the Trilogy is the better Siux. And Siux publishes no weights on most product pages, so the weight windows on our listings come from retailer sheets and should be checked against the box.
