11 Headset

Headset
The headset is the bearing for the bike fork in the ame. If
the headset has been properly adjusted, it will turn easily.
In doing so, no play should be evident.
The headset is subject to a large amount of stress due to
impacts with the road surface. This can cause it to come
loose or a ect its setting. Have the play and ease of move-
ment of the headset checked regularly by your specialist
cycle shop (for inspection intervals see
"Inspection schedule").
Checking the headset
If you do not adjust the headset properly or tighten
it too tightly, this could cause breakages. This should
therefore always be carried out by a professional bike
workshop.
If you ride with the headset loose, this could damage
the bearing shells or fork.
