OK, I'm riding an old road bike and I feel like I'm just not setup right. I feel that my arms are too close to my body and at times I'm not getting any power out of my pedals. I have the old road racing bars - curved at bottom - and I can't get comfortable in any type of aero position and I don't know what I can do. Does anyone have any "setup" diagrams to show me what it SHOULD be like? Suggestions?
