pls ignore the omitted details on the headset part and etc. tried to depict simple comparison between the use of SPACER VS QUILL ADAPTOR on threadless setup. the 'dashed line' is where the steerer tube is cut.
this pic is what i've tried with spacers once for my SS clunker. (1" steerer tube to 1" stem, the inside diameter of the spacer was hence 1").
as you see, there's one problem. where the expanding bolt is deployed inside the tube was way to far from the idealistic tightening point—right inside the top part of the headset. however, i didn't encounter a big trouble. maybe i was lucky not having had any front collision.
Thanks, everyone, for the explanation above! And Orange, love the drawing, dude! You should put that on the wall!
I guess the whole problem came from the fact I forgot that threadless stems DON'T have threads! Who woulda guessed? So something has to hold that headset together.... I've never owned or really seen a threadless stem set up in person so forgive my dumbness.
But, hey, the world now has a great new drawing so all's well that ends well....
And now some gratuitous pics of my Cinelli stem that just arrived in the mail complete with scary glowing red eyes:
