The knuckles that connect the front wheels to
the frame are supported by A-Head-type
headsets. (The following informations are only
valid for tricycles without front suspensions.
For those, please refer to page 73).
The headsets must be adjusted in order to let
the knuckles with the front wheels attached
turn easily without showing play.
To check the bearing play, pull the front brake
and grab the upper bearing cup with your
other hand. Now move your tricycle back and
forth. If the bearing has play the upper cup
moves noticeably in contrast to the fixed part.
In this case loosen the clamping screw of the
clamp above the upper bearing and tighten the
screw in the cap a bit more. Afterwards, fas-
ten the clamp again.

To check whether the front wheel turns
smoothly lift your bicycle at the frame so that
the front wheel moves freely above the
ground. When you hold the frame straight
and push the handlebars slightly they should
move smoothly from their middle position. If
the bearing is too tight, loosen the clamping
screw of the top clamp and loosen the hex-
headed screw in the end cap a little bit by
turning it counter clockwise. Fasten the clamp
again afterwards.
Danger! The hex-headed screw in
the cap only adjusts the play of the head
set bearing. This screw will not safely hold
the knuckle in the frame. Take care that
the clamp is tightened as prescribed after
you have finished your adjustment. Please
pay attention to the table of fastening
torques on page 88
The holding sheet of the mudguard is fixed with the cap
to the head seat
If your tricycle is not equipped with mud-
guards, there will be a spacer (5 mm) between
cap and clamp. When mudguards are installed,
the spacer is replaced by the mudguard
mounting.
After adjustment of the head set bearing, align
the mudguards in a way that they won’t touch
the front wheel.
