Here are the wheels I have on my Roubiax (Williams 30x). I've had them nearly a year and put a couple thousand miles on them and they are still true. I climb a lot of hills where I live and haven't had a broken spoke yet. They are made in the United States and the delivery/service has been impeccable. Highly recommended....
