1. Undo the M3 and M4 bolts by turning
them anticlockwise with a 1.5 or 3 mm
[0.05 in or 0.12 in] Allen key. Do not
remove the bolts completely.
2. a) To secure the headset, insert the 3 mm
[0.12 in] Allen key into the opening in the
upper spacer and turn this clockwise until
the headset is securely fastened.
b) To loosen the headset, insert the 3 mm
[0.12 in] Allen key into the opening in the
upper spacer and turn this anticlockwise
to loosen it. It is best to proceed in small
steps. A quarter of a rotation is often
enough to adjust the fit.
3. Check that the headset is now properly adjusted.
There are two ways of doing this:
a) Grip the lower bearing with your thumb and forefinger. Squeeze
the brake and move the wheel backward and forward. You will feel
significant bucking if there is too much play. In this case you will
need to tighten the upper spacer using a 3 mm [0.12 in] Allen key.
b) It is easy to check whether the headset is fixed too tightly - simply
lift the front wheel and allow it to swing from left to right. The
handlebar should swing it easily until the stop.
4. Once the headset has been adjusted as
required, tighten the M3 bolt with a
1.5 Nm [1.1 ft-lb] torque. The M4 bolt
must be tightened with a 2 Nm [1.4 ft-lb]
torque. Tighten both bolts in the clockwise
direction.
