Is that good for spoks?
It's largely irrelevant, since the difference between 1kg and 2kg for a pair of wheel can easily be swamped by aero differences, but it would be lighter than Hed3, Aerospoke or Corima if true, although Xentis claim 1390g a pair for their High-X so not the lightest

It's about average for this style of very-few-fat-spokes wheels. Normal wheels can be 1kg per pair for similar money. But normal wheels are less aerodynamic.
Wheels with less than 12 spokes or spokes thicker than 10mm are not allowed by the UCI in road races. These are for the track or for recreational/urban cyclists who like the look.
Referring to the dude upthread in the Philippines https://www.lfgss.com/comments/17069676/ They're here. https://bike-ahead-composites.de/products/wheels/biturbo-aero.html And only 1450 grams per pair.
Here they are on a Scott Foil .
