Siux Fenix Pro Mad Se

A racket made to mark a first professional title in Madrid sounds like a different product from the Fenix Pro 2026. Yet the published sheet barely separates them. That is the first thing to know. The second is that nobody has published a court test of this racket, so what follows is a reading of the specs.

Mad SE or Fenix Pro 2026: what the special edition changes on paper

The product page calls the Mad a special edition for Leo Augsburguer's first professional title, won in Madrid. The design carries references to the city. Those are claims from the retailer, and they describe looks and story.

The sheet tells a quieter tale. Both rackets list a 12K carbon face, a 38 mm thickness, a diamond shape and a high balance. Both name Augsburguer. The weight range is 360 to 375 g for the Mad SE and 355 to 375 g for the Fenix Pro 2026. The Mad SE is labelled Advanced, the Pro 2026 Professional. A changed label is only a changed label. It does not show that the racket plays differently.

The product page promises a top feel, but the meters read Low comfort

The product page claims a top feel rating and explosiveness at the net. Treat that as marketing. A feel rating cannot be checked against a spec sheet, and no reviewer has weighed in.

What the specs do say is less flattering for comfort. The comfort meter reads Low. The EVA core helps a little, but the heavy build and the high balance pull it down. Net play is a second doubt. The maneuverability meter is also Low, which does not match a picture of quick, explosive volleys. The product page also says the racket is built for attacking plays. That fits the power meter far better than the net claim.

12K carbon over EVA in a diamond: where High power and Low control come from

The face is 12K carbon with a 3D surface, over an EVA core. The product page says this gives a firm response and energy transfer at impact. Take that as the brand's view. The meters agree on the direction: power is High.

Three things drive it. The diamond shape moves the mass toward the top of the head. The high balance adds leverage on every swing. The weight adds momentum. Control is Low for the same reasons. A diamond with a high balance rewards a clean, early contact and punishes late or off-centre hits. Not a racket that rescues you. A racket that pays you back when you are precise.

The retailer lists the player profile as Power, which fits.

360 to 375 g and a high balance: what the heavy diamond asks of your arm

The weight range is 360 to 375 g, and the thickness is 38 mm. Those weights come from one French retailer, and the exact weight of your racket will sit somewhere in that range. That is heavy. Add the high balance and more of the load sits at the head.

What you notice on court is likely this. Smashes and bandejas gain from the momentum. Fast defensive blocks and quick changes of grip ask more of your wrist and shoulder. Long sessions can tire an arm that is not conditioned. If you have a history of elbow or shoulder trouble, the specs suggest caution. Both comfort and maneuverability are Low.

The retailer's level label is Advanced. Read it as a warning, not a boast.

Next to the Fenix Elite 6 and the Kuikma Power Carbon 26

The Fenix Elite 6 is the softer sibling on paper. It uses a 3K carbon face and lists 355 to 375 g, and its comfort meter reads Medium where the Mad SE reads Low. Control, power, maneuverability and sweet spot read the same.

The Kuikma Power Carbon 26 shares the 12K carbon face, the EVA core, the diamond shape and the high balance. Its weight range is 361 to 375 g. Its meters match the Mad SE. Kuikma's level label is Professional. If you want this profile, the sheets say the Mad SE is not the only route to it.

Balance in mm, head size, frame, handle: what is not published

Several numbers are missing. The balance in mm is not published, only the label High. Head size, frame material, handle details and the weight system are also not published. Those gaps matter. Two high-balance rackets can feel quite different depending on where the balance point sits. Until a reviewer measures it or the brand publishes the figures, treat the high balance as a direction, not a precise number.
