Nox Genius 18K Alum

Nox dropped the AT10 prefix for this 2027 version. The core, face and weight system all changed too, though only in name. That is the whole story on paper.

Two new labels and a renamed weight system

Compared with the 2026 version, three things changed. The core name changed, the face name changed, and the weight system was renamed, moving from an adjustable counterweight setup to something called Weight Balance. Shape, level, balance label, thickness, and the 360 to 375 gram range all stayed put. Handle spec is not published for either version, so that comparison cannot be made. None of this reads as a redesign. It reads as a relabeling exercise with a new weight system attached.

Medium control, high power: what stayed exactly the same

The five meters land in the same spots as the 2026 racket. Control, power, comfort, maneuverability and sweet spot all match. They also match the Nox Genius 12K Alum XTREM sibling. Control sits at medium, power at high, comfort and maneuverability both at low, and the sweet spot rates low as well. If the profile is what matters to you, this generation is not a step forward or back from the one before it. On paper it matches its 12K sibling, apart from the face and the balance label.

No balance in millimetres, no head size, no way to check the claims

Two specs are missing here: balance in millimetres and head size in square centimetres. Nox has not published either. That matters because balance label alone (Medium) leaves room for interpretation, and head size affects how the sweet spot behaves in practice. Without those numbers, you are relying on the label and the profile meters, not a precise measurement.

Dual Spin and Weight Balance: what Nox says they do

Nox describes the Dual Spin surface as a 3D texture with silica sand. The brand says it helps generate spin. Nox describes Weight Balance as a system letting players adjust balance to preference. Those are brand claims, not measured results. The product page also talks about aerodynamic tunnels and lateral perforations improving manoeuvrability. None of that shows up as a separate, verifiable spec, so treat it as marketing language describing intent rather than a measured outcome.

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

This racket shares its year with three siblings. There is the Genius 12K Alum XTREM, a Lite version with a softer HR3 White EVA core, and the Genius Attack 18K Alum. The Attack version swaps to a diamond shape and a high balance, dropping control to low in exchange for a head-heavier swing. The 12K sibling differs from this racket in two published specs: it uses a different face carbon, and its balance label reads Medium-Hard against this racket's Medium. If you want more pop at the cost of control, the Attack version is built that way. Against its direct predecessor, the AT10 Genius 18K Alum 2026, the differences are the word-level swaps already covered above.

Reading the specs without a review to check them against

There are no reviews on file for this racket, and no source has reported hands-on time with it. Everything above comes from the spec sheet and the profile meters built from those specs. That is a fair way to get a first read on a racket, but the numbers stand alone here. If a hard core and a stiff face at this weight sound like a concern for your arm, that question stays open until reviews appear.
