(Full) cArbon Forks
3. —(full) carbon forks
The (full) carbon forks which are
installed as well as carbon forks with a
upper shaft part made out of aluminium
are forks with a tapered steerer. This
has an external diameter of 1.5“ in the
area of the lower control bearing and
tapers towards the top to the clamp-
ing area of the handlebar stem to 1 1/8“.
Only handlebar stems and headsets
compatible with this shaft diameter may
be used and which are approved by the
bike manufacturer.
•
If the headset bearing lower cone
ring is driven into the bearing seat
with massive force there is a dan-
ger of damaging the forks. Fitting
a headset must be carried out by
a specialist technician. The shaft
tube external diameter in the vicin-
ity of the stem is designed for front
extensions with a clamp diameter
of 1 1/8”. Only the handlebar stems
with corresponding internal dimen-
sions and cleanly finished interior
surfaces may be used. The fitted
stem may project no more than a
maximum of 2 mmabove the edge
of the shaft tube end.
The front brake is fitted to the forks
using the special screws supplied by
the manufacturer with an M6 thread
with an internal hexagon (Allen screw®)
head. (SW 5 mm). The external diameter
of the nuts must not exceed 8 mm and
the maximum torque of the nuts is 8 Nm
(min. 7 Nm)
•
For carbon forks with a upper shaft
part made out of aluminium so-
called “ahead claws” be driven in
to adjust the control bearing. Un-
der no circumstances may this be
done for a (full) carbon fork. The
supplied insert for internal clamp-
ing should always be used to do
that or the screw insert for mod-
els with an internal thread used
in the carbon shaft. Use of the
“ahead claws” (full) carbon forks
can cause considerable damage
to the shaft tube and dangerous
total failure of the assembly may
even occur! The shaft length must
only be adjusted or modified by a
specialist technician.
Ideally a metal saw with low abrasion
rate or a metal circular saw with a
diamond saw blade and water cooling
should be used. In the event of dry
trimming adequate protection from dust
inhalation produced should be ensured.
Inhalation protection with a fine dust
filter and safety glasses are recom-
mended.
4. — Care instructions
Your carbon frame and your (full) carbon
forks should be cleaned regularly. Ordi-
nary paint care products with or without
silicon additive and cold to lukewarm
water to which may be added ordinary
detergent may be used. To be avoided
are solvents of any description, alco-
hols (e.g. ethanol or isopropanol), hot
water with alkaline additives or cleaning
with steam jets and pressure washers.
