Thanks to everyone who contributed to my handlebar thread. I just ordered the trekking bars from Nashbar, and should have them by the middle of next week. I'm still convinced that my stem will still be too low and too far forward to give me a really comfortable riding position, even with the trekking bars. I raised it to the maximum safe level (there's a mark on it to show that...), and it's still a bit lower than I'd like.
The bike is an older mountain bike, and takes a 22.2mm quill stem. I'm looking at getting a higher, closer to me stem than the one that's on there, and am trying to decide between an adjustable stem and an extra-long touring stem. Does anyone have any experience with either of these?
I really appreciate everyone's patience with my questions. I hope, as I become more experienced in this new (for me) area of "comfort" cycling, I'll be able to reciprocate.
