Giant Defy 2 2012 Chainstay

[Eviesdad1]

Hi,

I wonder if anyone can help?

I have a Defy 2 2012.

When I rub my finger along the chain stay on the drive side there is a section that feels pronounced - almost like a crack. On closer inspection it looks a little too perfectly formed to be caused by accident (if that makes sense). It is almost elliptical in shape and joins on the top. Unfortunately, I can't take a picture to show it properly.

I have never really noticed it before and wondered if I had a problem. Or is it there for a reason?

Is anyone else's like that?

Thanks

its a thin layer of extra lacquer/a plastic sticker to protect the frame from the chain.

most bikes these days have them, i think. certainly all the ones ive had do.
