I've been wanting to upgrade the DT Swiss R470 wheels on my Creo Comp Carbon, and I've seen a few different posts from those who have upgraded to Roval Terra C, R38, etc. I notice that my stock hubs are 12x110 front and 12x148 rear. Most of the replacements referenced are 12x100 and 12x142. Is there some sort of spacer required going to smaller hubs, or is the difference small enough that the dropouts and forks flex/adjust?
