Can anyone tell me what brand and model of chainrings are compatible with this crank on my 2023 Orbea Terra H40?
It seems to be an orbea own brand crank.
I am looking to buy spare chainrings 30 and 46t but can't seem to find a reference to it anywhere online ?
Terras seem to generally come with GRX cranks.
The rest of the drivetrain is Shimano, with GRX derailers.
Any help would be much appreciated.

A 46t + a 30t chainring will cost you almost the same as a full GRX 610 crankset (76 € in bike discount, for example). Buy that.
These look like a rebranded Prowheel RPG-621-TT cranks and based on their listing, it uses a 110/80mm BCD similar to what the GRX cranks have.
So try searching for chainrings that are compatible with that BCD spec or as someone else said, you can buy a GRX crankset instead.
