Exactly what I expected, which is to say there is a "correct" way to do it but it depends on who you ask. And of course it will be different for different people.

I find the concept of "ergo" bars amusing. Isn't everything on the bike supposed to be ergonomic? Weren't dropped bars supposed to be ergonomic back then or did they intentionally make them non-ergonomic? I guess ergonomics varies with the decade.

Back when I tweaked my first ten-speed in the early 70's I didn't know how the bars were supposed to be set. I found I liked them better with the forward throw section parallel to the stem. I threw together a quick diagram of hand forces to illustrate what I think are the reasons.

When the bar tilts forward the hand must provide more gripping, i.e more anti-sliding force. When the bar is raised, the direct thrust of the arm is more perpendicular to whatever part of the bar the hand is holding, so the required anti-sliding force is less. Plus it places the brake lever closer for quick reach when riding the tops and requires less rotation of the wrist to brake from the hoods. But of course it's different for everyone.

Thanks for the enlightenment,
