The problem could actually be the length of your stem OP, maybe it is too short....

But we really have to stop calling all stock Fixed Gear bikes, Track bikes. The Steamroller is not a track bike with track geometry. The larger ones(56cm plus) do have a 74 degree head tube angle but the fork is 38 degrees with room for 35c or 38c tires, I can't remember which. BTW OP, I am thinking of getting similar bars for my IRO Mark V Pro, to give me more of an upright position to make it more comfy for my son when I carry him in the baby carrier on my chest or back. They are similar to the bars on my Mama-chari(shopping bicycle) which are ugly as hell but great for an upright position.
