Handlebar height and angle.
Quill stem Threadless stem
Your bike is equipped either with a “threadless” stem, which clamps on to the top part
of the steerer tube, or with a “quill” stem, which clamps inside the steerer tube with an
expanding wedge. If your bike has a “threadless” stem your dealer may be able to change
handlebar height by moving height adjustment spacers from below the stem to above
the stem, or vice versa. You can also replace the stem with one that has different length
or rise. You can also adjust the angle of the handlebars. These adjustments should be
made by your dealer or by a professional bicycle mechanic. Do not attempt to do this
yourself, as it requires special knowledge. If your bike has a “quill” stem you can ask your
dealer to adjust the handlebar height by adjusting the level of insertion of the stem into
the fork. Note that a quill stem has will have a mark showing the “minimum insertion” or
“maximum extension” level. This mark must not be visible above the headset. With a “quill
stem” you can also ask your dealer to adjust the angle of the handlebars.
WARNING: A quill stem’s Minimum Insertion Mark (or Maximum Extension
Mark) must not be visible above the top of the headset. If the stem is extended
beyond the this mark, the stem may break or damage the fork’s steerer tube,
which could cause you to lose control and fall.
WARNING: On some bicycles, adjustments in the position of the steering system
can aect the tension of the brake cables. This can result in locking of the brakes
or can create excess cable slack which can make the brakes inoperable. There-
fore after each adjustment of the steering system, the brakes must be checked
before you ride the bicycle.
WARNING: Never extend the stem above the minimum insertion mark that can
be found on the lower part of the stem’s shaft!
