Cannondale says you shouldn't run spacers on top of the stem but they don't say that you have to slam your stem. You put as many spacers under the stem as you need to have a correct fit. You can ride with spacers on top of the stem for a while until you dial in fit. The reasoning for not having spacers above the stem is because the compression plug is supposed to add reinforcement to the steerer so you want the plug to be inside the portion of the steerer where the stem is.
