Recently borrowed my friend's single-speed w/ bullhorn handlebars for a couple of days. Really enjoyed the more aerodynamic position compared to my drop bars, and feel these would be awesome maybe with some cross levers for longer trips (though for now, I'm sticking with my drops). I was also thinking about how I've never really seen these on a bike with multiple gears (besides Tri/TT bikes). How do you think brifters would be on these? Has anyone done this? Any opinions, and pictures, would be awesome.
