    Carbon seam on One9 top tube

    Anyone else able to see a fairly pronounced seam running down the top of the top tube? To me it looks like two halves of the frame are joined at this location as it runs aalllllll the way from the headtube to the seat tube.

    I can't feel it through the clearcoat but I am wondering if it is manufacturing defect. I don't see one on my Air 9 RDO. When I look down and see it staring at me I wonder if the frame may ever just split in half on me.

    This on a '15 One 9. Atomic blue/glow in the dark. New to me.

    You can see the seams on plenty of carbon bikes that are kit is perfectly normal.

    If it is not separating, donít worry about it.
    Bicycles donít have motors or batteries.:nono:

    Ebikes are not bicycles :nono:

    There are no "seams" on carbon bikes. That is the remainder of mold flash from the curing process. It's not coming apart, it can't like that. Different paint jobs will bring it the carbon plys more than others because of light reflection
