Racework on aliexpress. i installed 6, cracked one. i have the old design. because they're wildly incompetent, nowhere do they tell you the torque. on the bright side, at 5.5nm w loctite, they work fine. I have to retighten regularly though. i think i paid 120 bucks or for the complete set, and the chainrings are very soft, but it's basically the hollowgram system, afaik.
the new design may not be prone to cracking anymore. they SOLD me a replacement crank as they refused to honour any warranty, but it was like 30 bucks, so fair game.
they also sold me the worst bar tape i have ever used. 1 of their carbon saddle cracked but i m still using it. i bought 10 or 15 chains from them, i ordered 12s, they shipped 11s, and they refused to do anything.
So. I thouroughly hate them. But their cranks are cheap and work. You can get double chainrings for 25 eur on aliX, shipped to Europe. And you can also buy an adaptor for shimano ones if you're tired of changing them too often (will depend on how you maintain your bike and how much you ride).
It's kind of like hating Apple and still using Apple products. Luckily, I just hate Apple, but dont use any of their products. I am a shareholder though.
