Hello, I have the following crank already that I intended to use as a 1x on my gravel bike:
https://www.aliexpress.us/item/3256807293043843.html
... but for one reason and another I never got around to putting it on that bike. Now, there's a tempting price on a 2x chainring with the same bolt pattern, and I'm interested in putting it on one of my road bikes specifically for low-range climbing:
https://www.aliexpress.us/item/3256807244493676.html
Can anyone advise me on whether or not I would need a different crank to put this chainring on, because it was (maybe) meant for a 1x chainring instead of a 2x chainring? Or is all of that sorted out in the design of the chainring so that it fits the crank regardless? Any help there would be appreciated, thanks!

Looks like they're both GXP 3 bolt, so it should work. Any difference bewteen 1x and 2x is usually solved with spacers.

Thanks! That's what I was hoping.

yes, it'll compatible with whatever sram 3-bolt chainrings you find. they also make a 110bcd spider you could use w/older chainrings.
it's got an odd spindle length for a road crank - I had to space it out w/shims to 73mm I think.

It looks like the same direct mount chainrings sold under Goldix brand. The Goldix chainrings has quite some complaints - too flexy and suboptimal shifting in general. If I were you, I would buy 3-bolt spider and chainrings from Stone/Pass Quest. From my experience they are very good and I am not looking anywhere else now.

Oof. I've already ordered it. Oh well, I suppose I'll find out for myself. Thanks!

we've installed and run many of these (different brand, same product afaik). they work but: they need replacing regularly, so dont overpay for them. If you ride tremendous amounts, you'll probably want to buy something else next. the machining isn't stellar (the area that contacts the chain). You can ruin them in seconds if you get a chain drop and just power through stupidly (a friend did that, it bent the small chainring, bin).
we've used 50/34, 52/36, 53/39. they're perfectly fit for function if you set things right. depending on the season i run different gearing, so paying under 25 eur per set for me is very compelling.
when you install them, there's a bit of play, so make sure you tighten the bolts in a way to not have play when pedaling forward. And use loctite, as it's the sort of bolt that gets loose and results in creaks.
i use waxed drive trains.
