STARNUT POSITION INSIDE THE
FORK STEERER TUBE. HEADSET
SPACERS ABOVE THE STEM
Never install head tube spacers above the
stem. Placing spacers above the stem, espe-
cially on forks with a carbon head tube, can
cause the head tub expander inside the fork
tube to be positioned above the lower limit of
the head tube, which can stress the materials
beyond the use for which they were desig-
ned, possibly causing accidents and serious
injuries.
The length of the fork head tube must always
be appropriate for the position of the stem in
the fork. The stem must always be installed in
the steerer tube of the fork so that both faste-
ning bolts on the back of the stem are posi-
tioned above the surface of the steerer tube
of the fork. Never mount the stem so that the
top fastening bolt of the stem remains above
the top edge of the fork steerer tube. This will
stress the materials beyond the use for which
they were designed, possibly causing acci-
dents and serious injuries.

in a manner consistent with the child´s riding skills..
These models are designed for recreational use only.
Avoid extreme use.
No do use in places with trafc and always wear a bicycle
helmet.
Always observe the age, height/weight limits.
Age: 3-6 years old.

MAXIMUM FORK LENGTH
(AXLE TO CROWN)
Always abide by the maximum fork length listed in the
technical specications section of this manual. The maxi-
mum fork length refers to the distance between the fork
axle and the bottom part of the head tube (axle to crown).
The failure to abide by this measurement and
install forks with a length greater than the
maximum specications can force the frame
beyond its design characteristics, possibly
resulting in malfunctions of the material that
could cause accidents and serious injuries.
L
MAXIMUM NUMBER OF HEADSET
SPACERS
Never use more headset spacers below the
stem than those specied for the frame. Con-
sult the specications tables to nd out the
maximum number of headset spacers that
are acceptable for use on an Orbea frame.
Installing more spacers than those permitted
can stress the materials beyond the use for
which they were designed, which can cause
accidents and serious injuries.
