Thanks everyone. Yes, "shoulders down and back" has been my mantra for a few years now. Thankfully, it's pretty much a habit and if I slide into bad posture, I'm aware of it pretty quickly (except when I'm here slouched at my computer). Elbows are no problem. I've got some genetic weirdness where I can't straighten them all the way, anyway, so they can't lock Core strength, yup, working on that with my trainer.

Now the fitting. A few of the shops around here offer fittings, but not the one I bought the bike from. So the guy at LBS #1 was very helpful, adjusted my other bike, showed me the Dolce (which I also really liked) and just taught me a lot. And didn't charge me. So can I go back to him with the bike I bought elsewhere? I'll be paying for the full workup this time, but I guess I'm afraid he'll find something wrong and I'll start to worry if I made the right purchase. It's really the bars that concern me. I can't seem to find just the right spot.
