I think the only 'bents that would have problems would be ones that use IGHs (internally-geared hubs,) such as a 3x7 or a DualDrive. I'll second the notion that there is no such thing as a 'standard' wheel size for bents. My stable includes 406, 451, 507, 559, and 622 wheels; and the 559 can be interchanged with a 571.
