I would have 3: "hoods", elbows, next to the stem. All I'm trying to figure out is how narrow is too narrow so as to render the position next to the stem unusable. Specifically, I would like to know if 37cm would be too narrow. WoundedKnee thinks so, and I think he's probably right, but as I'm not able to physically grab a pair of 37cm b123s myself some more opinions would be greatly appreciated.
