I feel like I'm supporting a lot of my weight on my arms when I ride my Surly Long Haul Trucker. It's got standard road bars and I usually stick to the tops and rarely use the drops. I've thought about using a straight/MTB bar, but that would mean all-new brake levers and shifters. What about a shorter reach stem and/or perhaps one with an adjustable angle? Would allow me a more upright stance and take some of the weight off my arms. Comments?
