Out of the box they look like nice quality caps. That's all I can say positively. As other reviewers have pointed out, installation is a nightmare. I followed all the instructions and one still came off on the first disc. I found it, again followed the instructions exactly, and about a week later it was gone. After this happened on 3 different bikes I finally gave up looking for them to reinstall. Save your money by spending more money on a better wheel cover set. If you don't like disappointment then this would be perfect for you.
