TECHNICAL MANUAL 13
EN
MAXIMUM TYRE WIDTH
This technical manual species the maximum size of the
tyres that can be mounted on the frame. Always follow
these guidelines when installing tyres on your bicycle.
Consult the technical specications chart in this manual
to know the maximum tyre width allowed for the frame.
However, the real measurements of the tyre circumfer-
ence and width may change from one manufacturer to
another. When installing a tyre other than that originally
mounted on your Orbea bicycle, check that there is at
least 6 mm between the top and the sides of the tyre and
any part of the frame or fork.
Consult also the maximum and minimum tyre width that
can be installed and a given rim depending on its inter-
nal width. Read the OC wheels compatibility table on our
website or the rim manufacturer's documentation.
Damage to the frame or components due to
the use of a tyre that does not comply with
these measurements is not covered by the
warranty conditions.
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.
Never install headset spacers above the
stem. Placing spacers above the stem, es-
pecially on forks with a carbon steerer tube,
can cause the expander inside the fork tube
to be positioned above the lower limit of
the steerer tube, which can stress the ma-
terials beyond the use for which they were
designed, possibly causing accidents and
serious injuries.
The length of the fork steerer tube must al-
ways be appropriate for the position of the
stem in the fork. The stem must always be in-
stalled in the steerer tube of the fork so that
both fastening bolts on the back of the stem
are positioned above the surface of the steer-
er tube of the fork. Never mount the stem
so that the top fastening bolt of the stem re-
mains above the top edge of the fork steerer
tube. This will stress the materials beyond
the use for which they were designed, pos-
sibly causing accidents and serious injuries.

INTENDED USE
The intended use of all models is ASTM Condition 3 Sport,
that includes Condition 1 and 2 as well as natural trails of
moderate difculty.
The use of a bicycle on this terrain requires technical skills
and may cause beginners to sustain injuries.
For information about all ASTM categories, consult the Ge-
neral User Manual.
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).
Rallon is not compatible with the use of double crown forks
.
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 se-
rious injuries.
