Nox AT10 Genius 12K Alum XTREM 2026

The 2027 Nox Genius 12K Alum XTREM has the same face, frame, shape and 360 to 375 g weight range as this racket. So the real differences come down to a core, a balance label and a few words about counterweights. That is a small list, and it makes this page easier to read than the long Nox naming suggests.

No reviews of this racket are listed yet. Everything below comes from the specs, so treat it as a reading of the specs, not as court testing.

Same face and weight in 2027: what the successor changes

Look at the Nox Genius 12K Alum XTREM next to this one. Face, frame, level, shape, surface, thickness and weight range are the same. Both are Professional teardrops with a 38 mm profile, linked to Tapia, and both run 360 to 375 g.

Three things change. The core goes from HR3 Black EVA to MLD Black EVA. The balance label goes from Medium to Medium-Hard. The weight system is described as 2 g and 4 g counterweights instead of a longer sentence. The specs do not say whether any of that is measurable on court.

HR3 Black EVA or MLD Black EVA: reading the core swap

This racket uses HR3 Black EVA. The brand's product page calls it a high-density rubber with maximum memory effect, and claims more power in every shot, especially smashes. That is the brand's description, not a measurement. What the specs do show is a hard core, and a hard core raises power and lowers comfort and sweet spot.

The successor's MLD Black EVA is a different label. Nothing published says it is softer or harder. Only the Medium-Hard balance label hints at a change, and a label is not a measured change. If you are choosing between the two, do not assume one is more forgiving.

2 g and 4 g counterweights: what you can adjust on a 360 to 375 g build

This is the part of the specs that a buyer can use. Nox lists an interchangeable counterweight system with 2 g and 4 g pieces, and says it is compatible with frame protectors. The aim is to adjust weight and balance to your preference.

What does that mean in practice? The racket already sits in a 360 to 375 g range, so you are tuning a heavy frame, not rescuing a light one. Small pieces will shift how the head feels in your hand. They will not turn it into a quick, easy racket. Balance in mm is not published, so you cannot calculate where the weight ends up. You find out by trying.

The handle has an Oversize Grip and a 30 mm grip extension. That gives you a longer handle to work with.

Hard core, carbon face: why power reads High and comfort Low

The face is carbon 12K Alum Xtrem and the frame is carbon. Add the hard HR3 core and the teardrop shape, and the meters read High for power. The same hard core and stiff face pull comfort down to Low. The heavy weight class does the same.

That is a clear trade. You get a racket that returns pace when you swing, and you pay in vibration and a smaller margin on mishits. The sweet spot reads Low, because the hard core lowers it and the teardrop shape only partly makes up for that. If your elbow complains easily, take this seriously. A softer, lighter racket is the fix, not a different overgrip.

A firmer feel with a balance of power and control, says the product page: the meters answer differently

The product page says the racket was designed with Agustín Tapia for players who want a firmer feel and a balance between power and control. The firmer feel fits the specs. The balance does not quite: control reads Medium while power reads High. The racket leans toward power.

The page also claims the aluminised carbon keeps performance steady in temperature changes, and that the Dual Spin surface boosts spin. Those are brand claims. No independent source confirms them yet.

Sorting the 12K Genius names, and what stays unpublished

The names are a maze. The Nox AT10 Genius 12K looks like a predecessor, but it is rated Advanced where this racket is Professional. It is probably another model, so do not read it as an earlier version of this one.

The Lite 2026 version is the closer relative. It shares the face and shape, uses HR3 White EVA, and weighs 355 to 365 g. If this racket sounds right but heavy, start there.

What stays open: balance in mm and head size are not published. The balance label is Medium, taken from a retailer. Tapia, a left-side player, is the named pro. Without reviews, that is the whole picture.
