Carbon Rim Issue – yay or nay?

Cleaning my Proven Xc rims at the weekend and noticed this line on the rear.  Perfectly uniform and can’t feel anything to the touch or the old finger nail test.

cosmetic or wrecked?

And yes, i am awaiting response from Hunt but wonder if anyone’s had anything similar

looks like a mould split line to me.

so nothing to worry about

mould line that’s been lacquered over, the sunlight caught the fibres and highlighted it in a way you’d not seen before.

… is a guess that someone might make.
