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 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 65mm up from the bottom with the words “max. height” or “minimum insertion".
