wear was on the inside of the cups ; Litespeed provided new cups at no cost ----as you probably know, the bearing cups are pressed into the headtube at the factory and become part of the Cane Creek ( or other) internal headset.
I like this design ---- each bearing sits inside a cup ; the cup wears and not the frame.
Litespeed offered no explanation but I'm satisfied with their fix and continue to like their product.
