Are they center to center or inside to inside? According to the manu specs on my bike, it would have come with 42cm bars, but they measure 44cm center to center and 42 from the inside. I am curious if anybody knows how Ritchey measures the width. I love my Biomax bars, but wonder if slightly wider would be better. I just want to make sure mine aren't already the biggest size available before I order another set. Thanks.
