My Trek 7.3FX has flat handlebars and I'm planning on doing a 4000 mile tour on it this fall. Obviously flat handlebars aren't going to work for that in stock form (Although the Ergo material they're made of with a nice big flat palm rest is a LOT better than anything else I've experienced)
From my research I can't go to drop bars without replacing my shifters and brakes as well, so I'd like to avoid that if possible. So that leaves Trekking bars. However, I was wondering what the difference would be between installing a new set of trekking bars vs. just putting bar ends on the bike. Trekking bars don't really get you any lower, so as far as I'm aware their chief advantage of flat bars is more hand positions.
Also, and this is probably an indescribably stupid question, but when installing drop bars, instead of having them point straight up, could you just have them point down at an angle? Then you'd be able to get down lower for windy stretches.
