19 Adjustment of handlebar/stem - Quill stem & threaded headset
3.2 Quill stem & threaded headset
Today‘s classic combination of quill stem and threaded headset
are still common on everyday bicycles since they allow good
adjustability of the handlebar height without additional compo-
nents. In this system, the headset with bearing is screwed onto
the threaded fork steerer independently of the stem. The quill
stem has a clamping cone which is inserted into the steerer
tube and firmly fixed from above with a screw.
Loosen the screw on the head of the stem by about two turns.
(fig. 1-3)
The stem should now be rotatable in the fork and flexible in
height.

The stem can now be positioned so that
it is exactly straight on to the direction of
travel.

Also the height of the unit of stem and
handlebar can be adjusted now.
Please make sure that the stem is not
positioned above the limit mark on the
stem.
