Is it possible to set up a 1" threadless fork this way: a 1" threadless headset and then a 25.4 mm seatpost clamp above that where the threadless stem ordinarily would be to hold the steerer in place; then leave out the star-nut and insert a quill stem into the top of the steerer? The steerer in question is long enough, and does have a 22.2 mm inner diameter, so the quill would fit.
The main issue would be whether the seatpost clamp would be enough to hold the fork in place. I'd rather not learn that the hard way!
Another issue would be how to get the seatpost clamp tight against the headset without a star-nut to pre-load it, but maybe there's a way to do it?
Has anybody seen this done, or have an opinion? Feel free to tell me it's a horrible idea. (I know simply using a threadless stem is easier, but the steerer is just a wee bit too short for that). I'm grateful for any insights.
