certainly some road wheels built at the extremes are made for light weight (sorry, LIGHTWEIGHT) in favor of durability , but by and large there are overlap in suitability of "road" wheels in cyclocross applications ---- i.e. works well with wider tires, are durable, etc.

its not really about road vs cx wheels its more about rim vs disc brake wheels as there are engineering considerations specific to each type in terms of hub, lacing, etc
