I've got some bars I really like - off a Kona Ute. They're like a cross between a porteur style and a moustache bar (only with the sweep upward, not downward). They're alu, and the main problem is, I want to fit bar end shifters. Being mtb diameter (forget what that is - 22mm?), my bar end shifters won't fit. Anyone know if there were ever any shifters made to fit the smaller diameter, or any other way of getting around it?
