FWIW, I built a fixed cruiser about this time last year. BMX bars, Ourys, sprung leather saddle, and a fixed wheelset with 700x38 cross tires. It was geared at 48/18, same as my fixed Monstercross bike, and it rocked. I don't know how it looked to others. Frankly, I didn't care. When riding it, with the pinwheel spinning in the breeze, well, it felt straight Pimp. Then the BB crapped out one day and I haven't fixed it since.

Maybe I need another project?
