Yes, for a standard single bike frame. Newer frames may have a special provision like a split frame that permits access through the rear triangle.

How do I retro-fit a Carbon Drive System onto my current frame?
In order to retrofit a Carbon Drive System to a frame, you may need to modify the rear triangle. The belt cannot be broken and reattached, so for a standard rear triangle, you’ll need a way to get the belt through the frame. Belts also need adjustment for installation and tensioning. Several ways of doing this are: horizontal dropouts (track forks), eccentric bottom brackets, or eccentric hubs.
