Headset
Loosen the screw of the clamp by one or two
turns.
Carefully fasten the end cap with an hex key 6
a little bit more.
In order to check whether everything works
smoothly lift the bicycle at the frame so that
the front wheel moves freely above the
ground. Lean the frame a little sideways. Now
the handlebar should immediately turn
smoothly.When you hold the frame steady and
touch the handlebar lightly it should turn
smoothly, without jolts, from its middle posi-
tion.
If the bearing is adjusted too tight, unscrew
the end cap a little bit. If necessary, you can
loosen the headset with a gentle blow of a
rubber hammer. Repeat the adjustment.
Adjusting the headset with mounted adjustment bushing.
Headset
The front fork is pivoted in the frame by the
steering head bearing, also called headset.
Due to heavy shocks caused by very uneven
roads, the headset may become loose.
Adjusting the play
The steering head bearing has to be adjusted
so that the fork turns easily with the front
wheel without having play.
To check the bearing play pull the front brake
and grasp with the other hand the upper stee-
ring head bearing.Then rock your bicycle hard
back and forth. If the steering head bearing has
play the upper housing distinctly shifts with re-
spect to the lower.
To adjust the bearing you need the adjustment
tube and the end cap with hex head screw
M6x30 (rigid fork) or the adjustment nut
(Airwings suspension fork) that have come
with your bicycle. (Equipped with the optional
Glideflex folding stem, the stem replaces the
clamp above the headset and there is a long
black spacer between headset and stem.)
Loosen the lower stem clamping screw and re-
move the whole stem.
Put the adjustment tube on the steerer fork
tube above the clamp. Screw the end cap tight-
ly into the steerer tube.
Caution! Do not ride with a loose headset.
This increases the strain on the fork and the
headset bearing.The headset may be dama-
ged or the fork may break.
Caution! Do not tighten the end cap very
hard. It is only used to adjust the play. If the
headset is adjusted too tight the surface of
the bearings can be damaged.The conse-
quence is a turning with jolts and rest posi-
tions.Then, the headset has to be exchan-
ged.
