The machining was fantastic, the colors were not. None of my spacers matched each other, in gold. I'm sure the black or the silver wouldn't be as noticeable. The gold is, however, instantly noticeable. The only reason I am not giving these one stars is that they technically accomplish the task, but look horrendous. Something you would not want to say about an aesthetic piece for your bike.
