These 2 lines are in the center of the seattube. Blemishes in clear coat or something else? What are your thoughts? I can always wait to see if things change over the next month or so.
I think it’s just a normal seam where the edge of the carbon cloth is wrapped on itself before the molding is set.
it can be felt when one slides ones finger over them, particularily the bottom one.
I thought it might be a seam issue as you stated, except for being able to feel it, which confuses me a little
Probably just a seam with poor finishing quality. Is it a cheap frame?
not exactly, but I’d rather not say what it is.
I for one would not mess around asking on the internet if you should be concerned about riding that tube. I’d be at a local bike shop asap! If nothing more then just piece of mind and maybe a piece of your head if it breaks.
