You can see my (lengthy) post here about my experience with belt drive, but I was CONSTANTLY getting flats on my Ghost; tried the tires it came with, added tire liners, added slime tubes, nothing worked well until I got the (heavy as a tank) Schwalbe Marathons. Now I want to get the slime tubes out but don't want to remove the tire to do so. But yeah, another vote for "not changing your own tires isn't really an option". Even though its virtually impossible to change tires 'in the field' on my ghost.
