I have the same bike same colour. I thought long and hard over white or black flow rims, I went with black, but looking at yours, white looks a lot better. I thought it would be too tarty, but it looks ace. Seat looks made for it too and the black crank looks great. I avoided black crank because they eventually look shit when the paint wears off, again I’m regretting not going for black. I think your build is almost aesthetically perfect, perhaps a white stem would look good, looks perhaps a bit too black up top. I hope you enjoy it as much as I enjoy mine.
