Since there were no defects, I tried to sell it, but even after lowering the price quite a bit, it wouldn't sell. So I further customized my original glossy low-carbon custom bicycle to be semi-matte and darker.
The semi-matte customization was done at Miami Custom, and the quality is really good.
The first one is glossy and the second one is semi-matte, close to matte. As expected, the semi-matte finish looks prettier to my taste haha
