I'm in the process of creating my dream bike. I've decided on a Rohloff hub with the Gates Centertrack drive. Given that flats seldom occur on nice summer days in front of combination bike shop/ espresso bars, I'm looking for design suggestions that would make fixing a flat, that is dropping the wheel and reinstalling and retensioning the belt as easy as possible. There are a number of possibilities in terms of dropouts or eccentric bottom brackets as well as options as to where to break the frame, so I'm looking for advice as to whether any particular combination would make doing the repair under the Murphy driven appalling conditions more or less difficult. For this, I'm assuming a full wheel removal and reinstall, figuring that if that was designed to be as straightforward as possible, everything else should go well too.

Thanks
