Wouldn't a hybrid with drop bars be a road or cyclocross bike? Although it does depend on what you mean by a hybrid...presumably you'd need to change the brakes, gear shifts and all sorts. Cheaper just to buy a drop bar bike in the first place (I assume you don't have a bike as are asking about bikes)
Bar ends are the usual solution on a flat bar bike to add more hand positions
I've read in a mag and been told that fitting drop bars to a hybrid bike is a big no no, when I asked why I was told that having the brake levers of a drop bar is not a good idea with disc brakes, something to do with the sensitivity of pulling the lever compared to a straight bar set up. To explain it further I was told it'd be like braking with your left foot in a car
I'd stick with normal bar ends. I wouldn't fancy having to reach for the brakes fast in an emergency if I was on those drop bar ends.. might just be me but I think they look dangerous... sorry my mistake I just had a look at other photos and saw you are supposed to add brakes to them... bit of an expensive way to go about things unless you needed new brakes/ shifters anyway.
It depends on the hybrid, if it a flat bar road bike its doable; I and a few others have done it with the sirrus. Braking is far from ideal though if you use sti levers, these don't pull enough cable for v brakes.
