Thanks everyone for the suggestions!
Yes - looking at putting this on a trail bike. right now I have the K-edge top-cap mount, but I don’t love it, I seem to bump my computer with my knee or something.
This one looks promising! I had a SRAM-branded mount on my old bike with 31.8mm bars. I mount it “backwards” over the stem, so it wasn’t out front.
Good to know, but I’d rather not mount out front. The MTB mount looks more promising, but they list that as max 31.8mm bar.
