Any question answered...

Shitty balls.

As some of you know I am selling one of my old road bikes.

I was just giving it a clean before its first test ride and noticed this doozy of a something on the top tube. I can't decide whether it is a crack or a scratch.

What should I do about making sure this is just cosmetic? I do not want to sell a cracked frame to anybody.

The frame has been used on a turbo all winter, mostly with high resistance. Could this fuck with the top tube?

I vote scratch. Weird shape for a crack innit.
