Weird lines on Mavic 217 SUP rims

[MMaister]

Hi,

I am about to buy a nice set of wheels with Mavic 217 SUP Ceramic rims. They look great but there are some strange hairline marks around the rims approx in their centerline. They appear mostly around the eyelets but some of them are in between. They certainly don`t look like classic eyelet cracks, but what else it can be? Have you seen anything like this?

thank you

I've got some Mavic 220s with lines a bit like that, I'm not sure what they are but I'm fairly sure they're not cracks.

These are definately cracks. Those rims are prone to cracking, especially near the eyelets. I have one NOS rim with exactly the same issue.
