tyres that can be mounted on the frame. Always follow
these guidelines when installing tyres on your bicycle.
However, the real measurements of the tyre circumference
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 6mm of
clearance between the top and the sides of the tyre and
any part of the frame.
Orca Aero 2022 is compatible with ETRTO 622mm wheels
(700C). Consult the maximum tyre width allowed in the
The actual external width measurements can vary inde-
pendently from what is announced by the manufacturer.
The radial clearance (between the outermost part of the
tyre and the lower part of the fork crown or the seat tube)
must be, at least, 4 mm. The lateral clearance (between
the outermost part of the tyre and the inner fork lowers or
the inner parts of the chainstays) must be at least 5 mm.
Consult also the maximum and minimum tyre width that
can be installed and a given rim depending on its internal
width. Read the OC wheels compatibility table on our web-
site 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.
TECHNICAL MANUAL
MINIMUM SEATPOST
I N S E RT I O N
the minimum insertion depth of the seatpost
or the frame on road bicycles with exclusive
Orbea seatposts. The failure to follow these
instructions can cause stresses on the ma-
terials beyond the conditions for which they
were designed and cause damage not cov-
ered by the warranty conditions, as well as
accidents that can result in serious injuries.
MAXIMUM NUMBER OF HEADSET
SPACERS
Never use more headset spacers below the
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, espe-
cially on forks with a carbon steerer tube, can
cause the expander inside the fork tube to be
positioned above the lower limit of the steer-
er tube, which can stress the materials be-
yond the use for which they were designed,
possibly causing accidents and serious
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 1, for
use on a regular paved surface where the tyres are intend-
ed to maintain ground contact.
For information about all ASTM categories, consult the
General User Manual.
