Thanks. I thought I read somewhere that large stacks of spacers above the stem can be bad. Logically, it would have something to do with the expansion plug being too high in relation to the stem. My concern is that there isn't enough of the expansion plug supporting the stem clamp. Also, the steerer is 1-1/8".
