Chainrings from Aliexpress: PassQuest, Stone, Riro, Raceduel, ...

[DrDanger]

I have used Stone 2X 48/33T made for SRAM's AXS flat top chains. I've used them for 3 seasons (approx 8000 miles) and they have worked well.

Open question: what are options suitable for 2x? i need 54/40, not 1x. I havent bought the crankset yet, so as long as a carbon crankset can run these chainrings, i'm interested.
Key question: what about longevity/ i've run 20-25$ dual chainrings (now on Ali they cost 50+), and they dont last. It's fine as long as it's cheap, but nothing's cheap anymore. Is it established that Shimano / premium chainrings last multiple times longer, or not at all?
I dont mind changing chainrings that cost 20. I do mind changing them if they cost 50, and the good ones last forever and cost 75, basically.

Longevity is heavily influenced by the grade of aluminium used. Cheap chain rings use a softer '6061' grade while more expensive chain rings such as these Pass Quest GRX compatible rings or these Magene rings, use 7075 grade aluminium. It's a fair bet, if you're surfing for chain rings on Ali and a product page doesn't mention 7075 then the rings are using the cheaper grade. I've been running the Magene rings for 6000km - not exactly long term - but they're doing just fine.

why are chainrings so expensive? shouldnt they cost 20 bucks, instead of 70+?

To be fair, they do cost like 20-30 EUR less in China than on AliExpress.
