    Giant Defy Chain stay


    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?

    Sometimes drive-side chainstays have a small depression for a margin of space for the outer chainring against rubbing. I have this on my Merlin Extrafat because of the big diameter chainstays.

    IDK about Giant's Defy but if the chainring didn't rub or scratch it, that might just be it - a depression for the bigger chainrings.
