HANDLEBARS AND STEM

Handlebar Stem

The handlebar stem fits into the steering column and is held
firm by the action of a binder bolt and expander wedge
which, when tightened, binds with the inside of the fork
steerer tube. When removing the stem, loosen the stem
wedge bolt two or three turns, then give it a tap to loosen
the wedge inside. Lubricate by first wiping off any old grease
and grime, then applying a thin film of grease to the part,
including the wedge, that will be inserted into the frame. The
height of the handlebar can be adjusted to suit your comfort
preference. If the stem is removed from the steering column,
you will notice a mark about 65 mm up from the bottom with
the words "Max. Height" or "Minimum Insertion".
WARNING
A quill stem's Minimum Insertion Mark must not be visible
above the top of the headset. If the stem is extended beyond
the Minimum Insertion Mark the stem may break or damage
the fork's steerer tube, which could cause you to lose control
and fall.
