I changed my bike's handlebar to a drop bar and I've been seeing a lot of people get the bar end shifters prolly cause they don't wanna spend for the road bike brake/shifter levers plus there may be incompatability issues unless you change out your whole drivetrain. I just kept my exisiting trigger shifters, you can either dremel the clamp to make a wider clamp to fit on the top of the drops or not worry about dremeling it and make about a 8 inch bar right under the dropbar to put your shifters like I did. it's almost the same as them being actually on the top and I can reach them perfectly while riding on the top too. You can attach a peice of copper tube to the stem either by a U bolt or a couple hose clamps. It doesn't add much weight and it looks good when you wrap it in the same color as your handlebar wrap but use colored electral tape and you can plug some end plugs like on your drop bar too. I have pics of mine somewhere in diff spots on here if you wanna look.
