mishathepenguin, 35 lb. is pretty close to what I consider fully loaded touring. The only CX bike I've had experience with is the Bianchi Volpe, which can handle that load. Weight distribution is perhaps the key when using any CX bike for loaded touring. Use front and rear panniers and load the front heavier than the rear. Bianchi fairly recently began to equip the Volpe with a low rider ready front fork.
