drum brakes and drop handle bars I have sturmey archer xfdd and  xrd5. Which brake lever are suitable for these and drop handle bars. The cable is  road type with a barrel rather than a nipple.
I can not find anything suggesting that these components require special parts, so it looks like any road bike brake lever should work well.

If you are replacing the shifter as well, then you should be sure to buy and indexed 5 speed shifter. It will be difficult to find a 5 speed brake lever / shifter combo, as most road bikes have many more gears.
