    Scratch on carbon frame. Is it something to worry about?

    Hi there,

    I've recently bought new Specialized Stumpy carbon trail bike. Brought it home and when studying the frame I've noticed that there are a strange scratch or something like that on the frame. Is there anything to worry about? Or maybe it's just a paranoia? I don't care about cosmetic looks, there will be much more scratches I think by using the bike, but it is my first carbon bike and I''ve heard that it is hard to investigate it is scratch or crack. Thank You for the opinions.

    First thing I would do is notify the seller of the scratch. Let them see it before you even take it out on a ride. That way your ass is covered in case something happens down the line.

    I'd be more concerned that the serial number has been blacked out.
    What's wrong with him??

    Thank You for the answer, I'll do that. I hid the number because I think this is private information, just for that.

    looks to be multiple paint flaws in that area, left and right of it

    looks a bit sketchy

    It's impossible to say. It could be a paint defect, a scratch or, because of where it is located, a flex in the frame popping paint off. If it's a brand new bike I'd be taking it back.

    No nothing to worry about in that photo.

    .In general you only need to worry when you wear into carbon layers. Usually there's a resin layer and paint to wear through first. Even then you need to wear through quite a bit of carbon for it to effect strength.

    What Pig and 127 said. There seems to be a lot of stress releif in that area for a new bike. Definitely take it back and least document it with the seller.
    It is no measure of health to be well adjusted to a profoundly sick society.

    Thank You for the answers, Guys I contacted the seller. They thanked about that photos and promised to contact the Specialized about this mark on the frame. In general seems to me it is only some kind of scratch, I think I will ride this frame without any stress now.

    Tap on it with a quarter... you'll hear the difference between ting ting ting and clunk (clunk is bad).
