one reason is nonadrive or octomanium or any other number of names for the same basic mechanical idea, the drives usually use 6 inch mechs and 6 inch traction wheels. i prefer to use a very standard, modular design strategy, with multiple options. there are many more options for 6 inch wheels than any other wheel set. closon, andymark, pneumatic, good omni wheels, mechanum. with 4 inch wheels many of these types of wheels must be custom made. the 6 inch wheel size is the most versatile. and while it is true that some sacrifice is made in order to gain this flexibility, it is such a small advantage that it doesn't really impact performance too much.
I already designed a frame that will accommodate any drive-train. one of the sacrifices of that frame, was giving up 4 inch wheels of any type.
