Adjusting the head set bearing play
The head set bearing has to be adjusted so
that the fork with the front wheel turns easily
without showing play.
To check the bearing play pull the front brake
and grab with your other hand the upper bea-
ring cup. Now move your bicycle back and
forth. If the steering head bearing has play the
upper cup moves noticeably in contrast to the
fixed part. In that case undo the clamping
screws and tighten the screw in the cap a bit
more.
To check whether the front wheel turns
smoothly lift your bicycle at the frame so that
the front wheel moves freely above the
ground. Lean your bike to the side. Now the
handlebars should moove smoothly immedia-
tely.When you hold the frame straight and
push the handlebars slightly they should move
smoothly from their middle position. If the be-
aring is too tight undo the clamping screws at
the side and loosen the hex-headed screw in
the cap a little bit by turning it anti clockwise.
Now move the stem upwards by swinging it a
little bit.
After you have adjusted the bearing play check
if the stem is adjusted in a parallel position to
the front wheel and tighten the two clamping
screws alternately with 8-10 Nm. Check the
clamping by trying to turn the stem against the
front wheel.
Check whether the handlebars move freely wi-
thout touching the frame or the seat.

Adjusting the handlebars
Caution! The stem fixes the steering head
bearing and holds the front fork with the
wheel.After the stem has been removed
these parts are no longer supported and
may fall down off the frame. Hold the fork
with one hand or secure the fork e.g. with a
cable tie at the frame.
