I keep seeing sweet belt rigs (more my style than, for example, the Soho), and after reading things about shafts, I'm back on board with belts.

I'm just not sure what I want. Internal gears? Fixed? I think I'd be fine with a singlespeed for commuting, as it's mostly flat. After spending 4 years riding a 35 pound dualie MTB, I may be ready to swing entirely the other way and go for a lightweight speedbike. So many choices.
My friend with a fixie is trying to talk me into building one. I've ridden his and it's evilly fast, but I ride all-weather and hate the chain bother.
