ADJUSTING THE HEADSET

The headset is an assembly of parts that connects the front fork

and the head tube of the frame. It is the rotaonal interface

that enables the fork to turn. There are two types of headsets:

threaded and threadless.

Adjusng a Threaded Headset

A typical threaded headset consists of two cups that are pressed

into the top and boom of the head tube. Inside the two cups

are bearings which provide a low fricon contact between the

bearing cup and the steerer. The short tube through which the

steerer of the fork passes is called the head tube.

Adjustment of the headset is needed if the headset is too loose

(shakiness), too ght (sness). Note: It is possible that the

bearings have become worn or damaged and cause sness.

Replacement of the parts may be necessary.

Conduct the following checks to determine if there is play in the

headset:

❶ Shakiness: Apply the front brake and push the handlebars

back and forth, front to back or if the bicycle is on a

workstand and the front wheel removed, push and pull on

the forks. If you feel a knocking sensaon or "clunk" it

means the headset is too loose. Important! Use care with

suspension forks, because the legs may have play in sliders.

Grab upper poron of fork. Figure 4.33

❷ Sness: Li the front of the frame so the front wheel is

o the ground. The handlebar and wheel should op to

one side or another. If there is drag or binding the headset

is too ght.
