it refers to the frame tiagosantos_ss received (here's his post including two pictures https://chinertown.com/index.php/topic,4309.msg65396.html#msg65396), and the quality issues. It had a couple of voids in the upper seat tube area. There was some back and forth with Lightcarbon but they ultimately agreed to send out a new frame to tiagosantos_ss.
I have put my order in a couple of weeks ago and i'm looking forward to receiving the frame early November. I hope, of course, that my frame will not show those kind, or any kind really, of QC issues.
"a couple". You're kind, i can count 7 on the 1st photo. And riding unbranded carbon things implies trust. If you see that, what is there to say the rest of the frame isn't like that?
you're quite brave ordering one. FYI, you can buy USB endoscopes for super cheap on alix, in your shoes, i'd 100% get one and make a conscious effort to inspect all tubes of the frame i receive, because composites manufacturing isnt trivial, especially now that we all want light frames again. If your layers aren't compacted properly (should be much less of a problem now that EPS / latex moulding is very widely used), or if you're straight up missing material in key areas, then bad things can happen.
Canyon is notorious for having seat tubes that crack, for example, so the structural integrity of a frame is not a given.
