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.

Adjustment

Headset bearing adjustment requires special tools and training.

Improper adjustment can result in damage to the bicycle as well as

threaten the rider's safety. For these reasons, we recommend that an

authorized dealer perform all necessary headset adjustments.

Headset Type

There are 3 main types of headset in common use today. The most

basic type is the standard, external headset where the bearings sit

outside of the headtube inside cups that are pressed into the frame.

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.
