Not an advantage for me. I much prefer flat-bar brake levers than drop bar brake levers. Maybe because I got shorter fingers and I can't seem to get enough leverage on drop-bar brake levers.
As I said, there are people who don't like drop bars, and I'm one of them. But unlike the OP, just because I don't like drop bars doesn't mean I think drop bars must suck for everyone.
I'd hate to see the OP get into a Coke vs. Pepsi argument.. Or a Ford vs. Chevy discussion.. Or a filet mignon vs. porterhouse, or...
