I can't help with the stem as I have treadless, but I have the trekking bars with an adjustable stem with a bag and I love the setup. I have the stem (120) at a 90 degree angle to push the bars out as far as they will go and sometimes I wish I had a little more. I think you will like them. I posted some pictures of mine under "handlebars". That was before I put the stem at 90 degrees. It's something you have to play with, but I find them very comfortable. Good luck.
