I decided i'm going to make my Steamroller a single speed or maybe even use a 3 speed Sturmey Archer hub (which comes in 120mm) just for those days when i just really can not be bothered, will eventually have at least 2 other fixed gears so may as well.
If your worried about your knees i would of thought a single speed with a fairly easy gear would be fine?
