I am trying a North Road bar (inverted with about 1 1/4 cut off the ends) on a thrown together fixie. I looks alot like a mustache bar but has a larger flat in the middle. I do not have very many miles on it yet but it seems to work ok. I set it up with non ero roadbike brake handles that I wraped with bar tape to give a large area for my palms to rest like the article from Brigstone bicycles describes. I started to put brake levers like I use on my bull horn bars it had a very smooth look to it but it would prevent having one more gripping spot.
