I could sand it back where the tyre rub is, I'll check it there.
Is it a just a coincidence that it's happened in the same place on both blades, or is that where the fork takes most of the stress? not sure if it's just the paint being weak there or a bigger issue.
looks a little funky, could you sand it back a little around the crack?
then you could def tell if its actually cracked, or if its just the paint.
