Because I happened upon a cheap scratched THM Clavicula on ebay. It came with new carbon rings, still in their packets. Haven't decided whether to fit them for a giggle or sell them. I haven't measured their thickness yet, but I imagine they'll wear even faster than normal with a too-wide chain?
I have no experience but carbon does not do well in areas of wear. Which is why people like Carbon-ti and Rotor make carbon chainrings with aluminium teeth
Y tho?
Don't worry about the thickness of the teeth, buy 11 speed rings and they'll be fine.
