Paul Thumbies as Stem Mounted Shifters?

I am building up a 1990s Specialized Sirrus frameset as a 1x9 commuter and am toying around with the idea of stem mounted shifters.

Would it be possible to clamp a Paul Thumbie mount on a 1" quill stem? Thumbies come with a 22.2mm clamp so it should fit on the stem ok, just wanted to see if anyone has done this and if there were any issues.

Thanks!

IRD makes a clamp for that.

I came across the IRD as well, but since this is a 1x9 setup I just need the right shifter mounted to the stem.
Can you remove the left side mount from this IRD version?

If its the right diameter, I don't see why it wouldn't work. It's just a clamp, after all.

I did it, and it worked OK as a single shifter. Sold the bike fairly soon thereafter, so I can't really comment on how well it really worked.

Jeirvine: Great, that's all I need to hear, I'll give it a shot. I'll update this thread if all works out and functions well.

What possible advantage is there to mounting shifers on the stem as opposed to the handlebars?

Presumably OP is using drop bars, or likes the look without bar-mounted shifters.

I'm not a huge proponent of it, but I am building this bike up for someone and that is what it requested, so I am trying to make it happen!
