I ride and race xc (sport class) I'm trying to get in a more optimal race position. I've had a professional bike fit done and was told, if I want a bit better performance to drop a spacer or two from the handlbars. I have a 100mm stem with 6 degree rise. After I dropped out only one spacer, it seems now that my arms are way too straight and putting extra stress on my shoulders and mid back. I don't have that natural, relaxed bend in the elbows anymore. So, my question is, should I just put the spacer back in, or change the length of the stem, or both, or just put it back to the slacker position it originally was and make do since it seemed like it wasn't such a bad position to be in?? Help racer girls, it's driving me nuts.
