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?

That really doesn't look like a crack to me. Just a scratch in the lacquer. Obviously that means nothing without defintive proof.

I'm no pro at this kind of thing, but maybe you could take some very fine sandpaper to it and see if it buffs out? If yes, its only cosmetic.
