HEADSET
Inspection
The headset bearing adjustment should be checked every month.
This is important as it is the headset which locks the fork into the
frame, and if loose, can cause damage or result in an accident.
While standing over the frame top tube with both feet on the ground,
apply the front brake firmly and rock the bicycle back and forth; if you
detect any looseness in the headset, it will need adjustment. Check
that the headset is not over tight by slowly rotating the fork to the right
and left. If the fork tends to stick or bind at any point, the bearings
are too tight.
Note:
If your bike is equipped with a threadless headset, please see
a qualified specialist for repairs and adjustments.
Adjustment
Loosen the headset top locknut or remove it completely along with the
reflector bracket, if fitted. Turn the adjusting cup clockwise until finger
tight. Replace the lock washer or reflector bracket and re-tighten the
lock nut using a suitable wrench.
Note: Do not over tighten or bearing damage will occur.

Always make sure that the headset is properly
adjusted and that the headset locknut is fully
tightened before riding.
Warning: Over tightening the stem bolt or headset
assembly may cause damage to the bicycle and/or
injury to the rider.
