If you're going to be using a trekking bar, most trekking bars I've seen use mountain components. This means you can use inexpensive Shimano "DualControl" levers for braking and click-shifting at your fingertips (or the SRAM equivalent, or grip shifters with regular mountain brake levers, or... you end up with lots of choices)
The only other thing to be aware of is that mountain levers pull the right amount of cable for v-brakes, not cantilevers or calipers.
