Thanks for everyone's feedback, there is definitely a crack.

I am in contact with Wendy from LC. I will keep you updated with how this goes.

Hello everyone, I am a long time lurker of the forum.

I just received the LCR0017 and this is my first carbon frame.

The package was in excellent condition and the paint is realy good.

However, I am asking for advice as I am wondering if there is a crack on the downtube.
 
Indeed, there is a place where I see a small crack in the paint, and when I lightly press it with my finger it makes a scary cracky sound.
See on the video (https://www.youtube.com/shorts/O2SybUxEs6I), I really press lightly and it is the only place on the frame where there is this sound.
I find it weird cause the frame is straight out of the box, I have just put wheels on it.
I have no experience with carbon frame and I don't know if it is just the paint layer or a crack on the carbon itself.

I send an email to lightcarbon and I am waiting for their answer but I want to have other opinions
