the reverse lever trick also works well on bullhorns when using road brakes, but that is a nice look you got there jim-bob

since using aero brakes was mentioned on moustache bars (i'm not sure if what I'm about to say has been said... forgive me as I"m a bit loopy from 2 hours of sleep ), I had the same setup on my 'stache bars with nashbar aero levers. The best way to get them routed was to install the right lever on the left side, and left lever on the right side, so the cable routes through to bottom of the bartape.
