So my rear wheel took a pretty hard impact today and I got a puncture on my tubeless setup. When I looked at the wheel afterwards I noticed a tiny almost crack on the rim, basically hairline sized. That's also around where the sealant came out from after the impact.
I can't tell if it's a crack from the impact or just something to do with where the rim joins. It's so small I really can't tell the difference. It also sits perfectly opposite the valve hole which makes me think it might just be from the factory where the rim joins together. The wheel isn't any more out of true than it was before, which isn't too bad at all.
Rim is a Bontrager Line on a 2023 Trek Roscoe 8.
Has anyone seen this before? Is there a way to tell a seam from a crack? And is sealant coming out at that spot after a hard impact normal?
Any help or advice is welcome.
