HEADSET

Inspection

The headset bearing adjustment should be checked every month. This
is important, as tt is the headset that 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-tighten by slowly rotating the fork to the right and left. If that
fork tends to stick or bind at any point, the bearings are too tight.

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 the 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.
Detailed Maintenance

SUSPENSION FORK

Some fork models differ from the one illustrated. Those models are not
adjustable and require no maintenance other than keeping it free from dirt and
grime.
Regular Maintenance
The following maintenance should be performed every month (if riding off-road)
or whenever you feel performance is deteriorating.
1. With the fork apart, thoroughly clean all parts.
2. Apply a thin coat of grease to the upper tubes, coil springs and all internal
bushings.
Reassembly
1. Slide upper tubes into lower tubes
2. Firmly hold lower tube and turn clockwise until it will not turn anymore.
3. Align the brake arch mounts on both lower tubes and install brake arch.
4. Tighten brake arch bolts to 70-80in-lbs(8-9.2Nm)
Check before each ride:
1. Make sure headset is properly secured.
2. Make sure the exposed portions of the upper tubes are clean.
3. Make sure the quick releases are properly secured.
4. Make sure the front brake cable housing is properly seated into the brake
cable stop.
5. Check tire clearance and clearance between the top of the front brake
straddle cable carrier and the bottom of the cable stop. Make sure the front
brake cable is routed to the brake cable stop located on the brake arch. Do
not route the cable through the stem or any other mounts or cable stops.
