Nox Genius 12K Alum XTREM

The AT10 prefix no longer appears in the name for 2027. The racket in front of you is simply the Genius 12K Alum XTREM, but Agustín Tapia's name still appears as the pro player linked to it. That is a naming change more than anything else. The specs underneath tell a quieter story than the label suggests.

A shorter name, the same signature player

Compared with the Nox AT10 Genius 12K Alum XTREM 2026, the shape stays teardrop and the thickness stays 38 mm. The weight range stays 360 to 375 grams too. The professional level tag carries over as well. What changed is narrower: the core moved from HR3 Black EVA to MLD Black EVA, and the balance label shifted from Medium to Medium-Hard. Nox also updated how it describes the counterweight system, though the counterweights themselves, 2 g and 4 g pieces, are unchanged.

What a core and balance change might mean

A shift from a Medium to a Medium-Hard balance label usually means a little more weight towards the head. No performance meters are published for the 2026 version, so a direct before-and-after comparison on control, power, comfort, maneuverability or sweet spot is not possible here. Read the version update as a spec change with an outcome that has not been measured yet, rather than a confirmed step up or down.

Medium-Hard on paper, but no millimetres to check it

Nox describes the balance as Medium-Hard, which usually points to weight sitting higher toward the head. But the exact balance point in millimetres is not published, and neither is the head size in square centimetres. That makes it hard to compare precisely against rackets that do list those numbers. Take the Medium-Hard label as a rough pointer, not a precise measurement.

What 12K Alum Xtrem carbon and Dual Spin are supposed to do

Nox says the 12K Alum Xtrem face reduces surface waviness compared with conventional carbon and adds stiffness through an aluminised finish. The brand also claims the Dual Spin surface, with its 3D texture and silica sand finish, increases spin. These are brand claims, not measured results, so treat them as marketing until independent reviews appear. The VCS anti-vibration system is a listed spec, an elastomer layer inside the handle meant to cut vibration reaching the arm, according to Nox.

Genius 12K, 18K or the Lite: picking inside one family

This is one racket in a wider family sharing the same year and the same pro player link. The Nox Genius 18K Alum uses a different face weave and a Medium rather than Medium-Hard balance label. Its five meters read the same as this racket, including the same low comfort and low sweet spot. The Nox Genius 12K Alum XTREM Lite swaps in a White EVA core and sits at an Advanced level tag instead of Professional. Its meters also match this racket point for point. Neither sibling solves comfort or sweet spot on its own; the differences between them sit elsewhere, in level tag and face material.

No reviews yet, everything read from the spec sheet

No reviews or sources have been logged for this racket yet. That is worth stating plainly rather than filling the gap with guesswork. Everything above comes from what Nox itself publishes, plus the version history showing what moved between 2026 and 2027. If you want a played-in opinion rather than a spec-first one, wait for independent reviews to land before committing.
