Just my opinion but I'd be concerned about the gearing on the CAADX. My cross had a 12-26 rear & 50/36 crank. I found that off road I would always be running on the lowest gear combo and still would need something lower. That's on single track, minimal to moderate climb. I've since changed to a 46/34 up front and experimenting what I can get away with on the rear (might be able to do a 30, but just put a 12-28 on the rear and will try it out tomorrow.
