Actually, the shim of the Specialized stem has a standard inner diameter for a 1-1/8" steerer. The stem itself has a larger inner diameter to accommodate the shim. If you remove the stem and shim, it is no problem to use a "normal" stem on a bike designed for one of these multi-angle stems. You just lose the adjustability.
