Adjusting handlebar height

Stem bolt

Top cap and bolt

To adjust the height of the handlebars spacers can be moved from below the stem and replaced above
it to lower the handlebars or moved from above the stem and replaced below it to raise the handlebars
(picture 3)

Stem spacer

As the stem is not a right angle it can be turned over to offer further height adjustment. To do this remove the stem cap (picture 4) and remove the stem as you have done with the spacers, turn it over (pictures 5 and 6), replace it and re-fit the handlebars.
Re-fit the top cap and bolt, do not tighten bolt yet.
Now check for play in the steering (headset) bearings by sitting on the bike and holding the front brake on and rocking the bike backwards and forwards. If there is play you will feel a ‘knocking/movement’ in the bearings. Tighten the top cap bolt very gradually until the point when there is no play in the headset then stop. If it is over tightened the steering bearings will be compressed and the handlebars will feel stiff and notchy to turn.

Check that the handlebars are aligned with the front wheel and tighten the bolts on the side of the stem (picture 1). These must be tightened alternately half a turn at a time until they meet the recommended torque settings (91.8 kgf/cm or 9.0 Nm). Do a final check for play in the headset as described in section 6.
It should now look like this... (picture 7, 8 or 9)
