Anyone use them? I have several multi-sport friends encouraging me to get some for my bike before my next duathlon. I'm not sure I see the need or that they will fit well on my narrow handlebars. I believe mine are 40cm--pretty narrow. As it is my Garmin "pseudo-wrist" and quick-release mounts take up a lot of real-estate. I'm not sure there would be room left for my hands if tri bars were added.

I should add that I am reasonably comfy in my drops for a fairly long distance and my next du only has a 20k bike leg. I don't have any other duathlons planned until next Spring, so I don't know that I'd even bother this year.
