I have a Scott ridgid frame that I tour on a bit. My goal is to tour a lot of the coast of Maine. I need help on changing or adding to my bar setup. I have bar ends on it now which allows me 2 positions for my hands, but they still get sore. Any ideas of what to add, IE: areo bars, or another set up that allows for more hand positions? It is an older model with grip shifters.
