Yeah, it is mounted on the stem. My bars are flat on top. Oddly enough, that was stock on the bike (Orbea Marmolada) and while I questioned it at first, I now like them a lot. The LBS mounted the computer on the stem just because it was easier. I suppose I could mess around with mounting it a different way if it is an issue. Bikes are getting so creative now! I learned today that the Lemond (DH's bike) won't accept the workstand because the tube is larger. I remember when tubes were tubes....
