just a heads up: after about 170 miles on the specialized bars I give them a thumbs. I still wouldn't call it perfect but maybe I can dial the fit some more.
i went with 40 after getting measured at the LBS. He said I was between a 38 and a 40 with my wrist bones showing me as closer to 38. Well I've never thought about my wrist bones as indicative for my handlebar size. But he said that if I was using 40 and didn't have problems then I should just stick with it. besides I didn't want to give up the room on the flats of the bars.

is it weird that I have to change my seat position with my bars? I actually want to change my seat altogether.
