threaded.

i prefer threadless but on the techno, nothing looks better than a nice quill stem.

my dad has a techno and got it with the threaded fork but eventually updated it to a carbon threadless setup. ascetically, i wished he would go back

edit:

if you want a nice italian quill stem that allows you shange lengths without taking your tape off, look at the deda murex. i just sanded and polished mine. it shines like chrome:
