You're considering a country bike. Its not really a CX bike. Its a road bike that draws from the mountain bike, hybrid bike and CX bike heritage to create a versatile pack mule of a bike.

My Schwinn Super Sport DBX is typical of the line. A few are up for sale on the Bay now. Great bike for trails to rails riding as well on pavement. Other bikes in this mold to look at are the aforementioned Trek Crossrip, Salsa Vaya, Surly Ogre and the Soma Saga. They will all be built with a relaxed geometry, have braze on mounts for fenders and racks and they will be able to accept fatter tires than the typical road bike. And you can ride them places impassable for a road bike.
