But that's a different kind of stress that's weighing on rims. The bars are just held in the middle by a metal clasp. Think about, that's exactly how you would break a piece of wood if you're trying to break it. Imagine riding up a steep hill (especially with a ss/fg) and using the bars for leverage or making some emergency maneuver - that's a recipe for a disaster with wooden bars.

But if you're so confident, why don't you use, eg a wooden seat post and tell us about your experiences?

That said, they look very stylish.
