I have been searching Aliexpress looking for a lighter-weight, lower cost, Carbon cranksets, that use 30mm spindles and fit Cinch chainrings.
All I seem to be finding are DUB 29mm cranks. I am already heavily invested in RaceFace Next R and SL Cinch cranks and would like to find compatible alternatives.
Anyone run across these?
Thanks.
I know it's not answering the question, but why not use a reducer like this?

DUB is effectively just 30mm bearings with a reducer to 28.99mm, in much the same way that Shimano use a 25mm bearing and a reducer down to 24mm. If you've already got PF30/BB30 bearings installed in the frames (which I assume is why you're seeking 30mm cranks), a reducer and a DUB crank seems like an easier solution than trying to find 30mm cranks (of which there are very few Chinese options now).

Fantastic! I hadn't thought of this option. I will consider this. Aliexpress sells the adapters for a lot less than other online stores.
I still would like to see if anyone posts a 30mm based carbon crankset

Tolerances on metal on metal for 30mm axles are terrible on non Chinese brands, the spacer to dub will mitigate this.
