One crankset I ordered with bottom bracket (dimpled fake Ingrid), the BB was complete trash, like unable to install crank without pushing shitty seals off. I would assume this is how most of these bottom brackets are. Just use Shimano for any 24mm spindle.
I’ve been running the Goldix kids cranks in 155 and 160. Functional, main strange things is that they need a pile of spacers on the NDS and the Q is kind of wide.
What brakes are these ripping off? What’s the reach? https://www.aliexpress.us/item/3256807699030513.html?

This page has slightly better pics for trying to figure out what’s going on.
They seem to be geometrically like a TRP980 or Dura-ace direct mount.
Each arm’s pivot location is off to the side, like a centerpull. The nearer arm has a lug or pin or protrusion that acts on a bit of the rear arm (where the set screw is on the TRP). That’s what helps to make both arms pivot in sync with each other.
(note small pin head in the center of the wider arm, that I think the other narrow arm rests on. Not adjustable like the TRP above.)
