It's important that the top plate remain parallel to the bottom plate to apply equal force to the handlebar. To achieve this the four bolts
must be tightened at the same rate. To achieve this tighten each bolt with the tool provided until you feel them start to "grab" (beginning
to tighten). Now spin the handlebars up to the correct riding position and continue to tighten the four bolts.and repeat the steps.

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 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 then 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
65mm up from the bottom with the words "max. height" or "minimum insertion."
Never ride a bicycle if the stem has been
raised so that the max. height/minimum
insertion line can be seen.
Warning: Over-tightening the stem bolt
or headset assembly may cause damage
to the bicycle and/or injury to the rider.
When refitting the stem, make sure the handlebars are correctly aligned and
tightened using the appropriate hex wrench or Allen key.
