Agustín Tapia begins 2026 with a major evolution of his racket line at NoxThe AT10 Genius range is now available in three models: 12K Aluminum Xtreme, 18K Alum et 12K Aluminum Xtreme Lite.

Despite their shared design, these versions offer distinct sensations, as highlighted by laboratory measurements. Extreme Padelthanks to the protocol X-Compare, an analysis system based on physical data and not on subjective impressions.

This protocol is based on standardized tests: weight, balance, inertia, frame and string stiffness, twistweight, power, and comfort. These measurable parameters objectively reflect what players perceive on the field.

To measure rather than to feel

Each player interprets a racket differently. Scientific measurement provides a common basis and allows for precise comparison of in-game behavior.
Here are the results obtained on the three AT10 Genius 2026 models:

Model	Weight (g)	Balance (mm)	Vertical stiffness (Ra)	horizontal rigidity	Swingweight (kg·cm²)	Twistweight (kg·cm²)
AT10 Genius 12K Aluminum Xtreme	363	266	64	88	174,0	18,9
AT10 Genius 18K Aluminum	367	260	62	88	173,8	17,9
AT10 Genius 12K Alum Xtreme Lite	352	259	61	87	159,7	18,9

Deciphering the measures

Sieve stiffness (Ra): the central indicator

Vertical rigidity reflects the behavior of the striking surface:

The higher the value, the firmer and more reactive the sieve.
The lower it is, the more supple and tolerant the sensation.

→ 12K Xtreme: 64 Ra, the firmest profile.
→ Lite: 61 Ra, the most flexible and comfortable version.
→ 18K: 62 Ra, intermediate position.

These discrepancies directly influence the perception of power and control.

Horizontal rigidity: frame stability

Measured via a lever applied to the head, it determines the deformation of the racket on the handle/head axis.
All three models display a very stable overall structure (87 to 88), comparable to that of premium rackets on the market.

Weight and balance

The distribution of mass determines maneuverability and stability:

12K Xtreme : intermediate weight but head-heavy balance → stability and power.
Small : lighter and more balanced lower down → speed of execution and comfort.
18K : moderate balance → control/power compromise.

Inertia (swingweight)

Inertia indicates the racket's ability to generate dynamic power:

12K Xtreme: 174,0 → dense impact, tight trajectory.
18K: 173,8 → Similar behavior, but smoother.
Lite: 159,7 → Notable maneuverability, fast strikes.

Twistweight

This parameter measures torsional resistance during off-center impacts.
La 12K Xtreme and Small display 18,9, indicating very good lateral stability; the 18K is slightly lower (17,9) but remains solid.

Analysis of the three models

AT10 Genius 12K Aluminum Xtreme

Power – precision – stability

The stiffest and heaviest version is at the front. Its high inertia allows it to produce a crisp impact and efficient energy transfer.
It requires good centering but rewards a committed move.

profile: Experienced player or competitor seeking maximum precision and offensive efficiency.

AT10 Genius 18K Aluminum

Balance – control – gradualness

With more moderate stiffness and a slightly lower twistweight, this model proves to be more forgiving.
18K aluminized carbon provides a more progressive feel and better forgiveness.

profile: Experienced player seeking a stable compromise between power, control and comfort.

AT10 Genius 12K Alum Xtreme Lite

Lightweight – maneuverable – comfortable

Lighter and with reduced inertia, it facilitates explosive movements on the fly and in defense.
Its structure remains stable despite its lower weight, but generating power will require more physical effort.

profile: player looking for a handy, easy-to-access and comfortable model.

On Nox AT10 Genius 2026 put through the wringer using the X-Compare protocol

Summary of X-Compare ratings

Criterion	12K Xtreme	18K Alum	12K Xtreme Lite
Control	87	85	72
maneuverability	74	70	82
Comfort	68	69	79
Power	87	85	72
Spin effects	97	97	97
Ball exit	74	78	70
Tolerance	65	74	74

The hierarchy confirms three clear identities:

12K Xtreme : high power output and stability, but demanding.
18K : overall balance, versatility.
12K Lite : maneuverability and comfort, ideal for a fast arm or fluid playing style.

With the AT10 Genius 2026 range, Nox offers three models with distinct personalities.
Thanks to the measures of the protocol X-Compare, Extreme Padel allows players to precisely identify the racket suited to their style, based on verifiable data rather than impressions.
