Not to be a Debbie Downer, but I do feel that belt drives are slightly oversold. Having worked on them and test rode them, I am not at all convinced the upsides outweigh the downsides when compared to a chain drive system. Issues with squeaky noises (largely addressed with the new centertrack design), picky alignment (again, centertrack is better), tensioning, and limited cog/belt sizes keep me from wanting to jump into belt drives on my personal bikes.
