Raising the handlebars is the best thing I've done. My neck started bothering me whenever I was riding my Trek 560, I raised the handlebars about 1/4 inch and the pain went away. I went from 23 to 25 mm tires, dropped 10PSI and the ache in my wrists disappeared as well.
My new Hunqapillar is set with the handlebars just above the seat level and after my first 25 mile ride I had now aches, pains or stiffness anywhere.
