Well, I'm building up a single-speed based around a 'cross frame using a ceramic bearing BB... I'll let you know how it goes when my frame comes in.
note: ceramic BB won't let you bike be lighter, it won't let you spin faster... but on the long haul (more than a few miles) you'll lose less energy in to friction. If you're thinking of doing this on a pure track use bike probably the only time it'll be worth it is if you're trying to brake the hour. But, it won't help you get to the coffee shop faster. Maybe you'll be a little less worn out at the end of the day if you're a courier though.
