I can sell you some laser cut carbons with ceramic bearings for $1,200. So that would make them better?
BTW - you can't 3D print carbon fibre that I know (composite - yes, carbon fibre - no). And why would you 3D print those?
True story.
But some ceramic 13T pulley's on. Shifting went down. So put Shimano back on top, other on bottom. All is good.
