Looking for carbon 1 1/4'' Stem (31.75mm)

[chlt3m4f10x4cln]

Hi all,
i was looking on replacing my aluminum stem on my canyon with something from aliexpress like og evkin or similar brands. But unfortunately i cant find anything. Am i not looking correctly or do the chinese manufacturers not comply with canyon's weird headtube diameter at all?
thanks

The search term you might want to consider is "OD2"
But not a lot of options on OD2 carbon stems, the Darimo clones from Odin Zeus among them (not sure they can be trusted...make up your own mind)
