As I'm getting back into cycling, part of what has brought me back has been the simplicity of a fixie. It has improved everyting about my riding, my power, strength, endurance, speed, cadence, spin, cornering and general bike handleing skills. But then again, I like brakes and can't afford replacing tires every week because of skiding.
Sure it takes some getting used to, but try it, you'll like it.
