Just a word of warning. Creo 1 had 12x148 mm Boost rear hub spacing, making it slightly non-standard as the standard size is 12x142 mm.
Higher models of Creo 1 came with Roval Rapide C 38 carbon wheels. The rear hub size is 12x142 mm. I know Specialized can provide a set of spacers to match the wheel to the 12x148 mm frame. Mike, please be careful. Why wouldn't you ask your Specialized LBS how to handle the matter?
Also, bear in mind you have to transfer the rear wheel magnet bracket onto the new wheel (I think it is Centerlock type).
