WHen I had my bike assembled, I had them put on a pair of Profile Design Century bars. They're nice enough, but I found that I really missed the hands on top riding position. So I took mine off and they're sitting on a shelf. I've tried riding bikes with aerobars where the armrests flip up, but my experience is that after a while, they became noisy....annoyingly so. If you don't mine not having the option of riding the tops, then the PD Century bars are fine. I missed that position though.
