Okay, potentially dumb question since I live exclusively in threaded-steerer territory: On one of his personal rides, Sheldon Brown shows how he raised the bars on a threadless steerer without using spacers by securing the headset with a correctly-sized seatpost binder. If the ID of a given threadless steerer is already suitable for quill use, couldn't a person just use a binder to secure the fork and thereby swap to a quill stem without modifications?
