I like them, but I have taken them off of the last two bikes they were on.

I use grip shifters because that's the only thing that works with my current gear hub, and the grip shifter assembly can only be placed at the open, straight section of the trekking bars. I could not work it around the bends for different placement options. So even though that may not have been the hand position I was in most often, I always had to return there to shift.

When I stand up and pedal, it seems a little more cramped. There's no "inside" the bars to occupy. Obviously standing upright is not my usual riding position, but I do like that when I do it on my wide Albatross bars, I can pretty much stand between the ends of the bars.

I feel like the outside position is kind of wide and too straight (almost horizontal with the top tube on mine). I find the angle of the flared A-bars more comfortable.

So much of the bar is given over to different hand positions, that it can be hard to mount much on the bars without interfering with a position. With a crown mounted headlight, a stem-mounted bell, and my computer mounted on to my stem, I was able to make it work, but trying to get all of that on the bars might have been a challenge.

That's not to steer (heh) you away from them. Those are just issues I noticed. If the bars are comfortable, then any other issue is worth working around. I found that A-bars were more to my liking, so that's what I'm using, but every now and then I try out the trekking bars somewhere again because they seem like a good idea. I still think there's a bike out there where I will like them, but for now they're not installed.
