I picked up a no-name aluminum mustache bar from Mod Squad Cycles in Harlem today. I was actually looking for a Jeff Jones style Hbar or a set of Mary bars for my singlespeed mountainbike but ended up throwing these bars on a few blocks from the bike shop and really like the way they feel on the fixed gear.
They're much wider than my old sawed-off riser and they also position my hands a good two or three inches farther forward; changing my riding position a bit, but it feels really comfortable. I have the bars flipped upwards which puts me in a slightly more upright position and yet still feels aggressive and comfortable for applying a lot of torque in a sprint. I was able to chug right up Broadway coming north under the bridge at 125th.
