Recently bought an old aluminum Trek Speed Concept frame and noticed this scratch/crack on the top tube (thumb for scale). Anyone have any experience on whether this is a scratch or a crack? I can feel it if I run my fingernail over it. Thanks!

Tap it with something. If its a cracked frame, it MIGHT sound different. If it were me, I would mark the ends of this “crack” with something, marker, tape etc. Ride the bike like normal for a while, see if it grows or remains the same.
