The area where the crack is, on the top side of the down tube on the inside of the front triangle of the frame. There's no way that could happen in shipping if the box isn't damaged.
From the video and pictures, it looks more like the outer black paint has come loose during packaging or shipping.
The frame will undergo multiple quality inspections before it is completed, and then it will be painted and the aluminum alloy parts with water bottle screw holes will be installed.
The quality inspection in these last two processes is only an inspection of the surface appearance.
Cracks may come from handling or rough treatment during transportation.
We will improve this based on feedback
