6.0 Guarantee and special ex gratia
settlements
Services under the guarantee are provided
only in the event of faulty materials or manu-
facture and never in the event of fatigue or
overload stress damage. We provide 3 years
guarantee on our frames and forks and we
also oer special ex gratia services.
Risk of Personal Injury and Material
Damage!
If you d iscover d amage t o your fra me and/or
forks you may send the damaged frame and/
or forks to us for assessment and an estima-
te of possible repair costs via your dealer.
Transport costs in every case are borne
by the customer. Following assessment of
repair costs the repair is carried out either
fre e of charg e or you will re ceive an ad vance
estimate of repair costs.
4.0 (Full) carbon forks)
Our full carbon forks and carbon forks with
aluminium steerer have a shaft diameter
of 1 1/8” in the clamp area one of the stem.
Near the lower bearing race the forks ts the
following headset sizes; 1 1/8”, 1 ¼” or 1 ½”.
Only headsets and stems which are designed
or approved according to the frame and fork
specication by the bike manufacturer may
be used.
Risk of Personal Injury and Material
Damage!
If the headset bearing lower cone ring
is driven into the bearing seat with mas-
sive force there is a danger of dama-
ging the forks. Fitting a headset must
be carried out by a specialist technici-
an. The shaft tube external diameter in
the vicinity of the stem is designed for
front extensions with a clamp diameter
of 1 1/8”. Only the handlebar stems with
corresponding internal dimensions and
cleanly nished interior surfaces may be
used. The tted stem may project no mo-
re than a maximum of 2 mm above the
edge of the shaft tube end.
•
The front brake is tted 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)
Risk of Personal Injury and Material
Damage!
Carbon forks with a steerer made of alu-
minium may be assembled with a so
called “star-nut” in order to adjust the
headset . When doing this the fork should
not be assembled on hard surface in order
not to damage the fork.
In this case the provided so called “expan-
der” or “thread insert “ must be used on
a full carbon fork. The use of a so called
“star-nut” on a full carbon fork will lead
to a serious damage of the steerer tube or
dangerous failure of the fork. The length of
the steerer tube can only be cut to size by a
professional bicycle mechanic.
•
Ideally a metal saw with low abrasion rate or
a metal circular saw with a diamond saw bla-
de 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 ne dust lter and safety glasses are
recommended.
5.0 Care instructions
Your carbon frame and your (full) car-
bon forks should be cleaned regular-
ly. Ordinary paint care products with or
without silicon additive and cold to lu-
kewarm water to which may be added
ordinary detergent may be used. To be
avoided are solvents of any description,
alcohols (e.g. ethanol or isopropanol), hot
water with alkaline additives or cleaning
with steam jets and pressure washers.
7.0 Liability
Risk of Personal Injury and Material
Damage!
The manufacturing company accepts no
liability for accident damage or conse-
quential loss. The user bears the risk in
the event of personal injury and material
damage. The manufacturing company ac-
cepts no liability for damage or accidents
caused by improper use of the frame and
failure to comply with the stipulations in-
dicated here.
8.0 Quality Assurance and rigidity testing
•
Every carbon frame ready for delivery and
every set of full carbon forks are subjected to
a rigidity test.
When travelling by air or on journeys
where the “bicycle“ luggage item is not
checked with regard to damage-free sto-
wage, adequate protection of the frame
and forks must be ensured (e.g. by using
suitable hard-top cases etc.)
The decision as to whether a repair is to be
carried out free of c harge rests solely with the
manufacturing company and in no circum-
stances is there any cl aim to cost-free repair.
The special ex gratia provisions only ap-
ply to the rst owner.
Only cleaned frames or forks are accepted
for guarantee work!
•
In the event of frame or fork complaint
claims we reserve the right to apply a
reduction in value based on the duration
of use.
Risk of Personal Injury and Material
Damage!
The guarantee is rendered invalid in the
case of damage, which is attributable to
incorrect assembly, misuse, unauthorised
modications or mechanical working of
frames and fork components (drilling,
milling, ling, sawing etc, on frames or
forks manufactured by us.
The n al decis ion as to wh at exte nt a claim
under the guarantee exists is a matter for
the management of the manufacturing
company.
•
For each frame height and each set of forks
a rigidity tolerance range is dened in preli-
minary testing. Only frames and forks which
come within this tolerance range leave the
factory.
•
The rigidity test is used as a Quality Assu-
rance measure and is performed on the
company’s own test rig. To do this the frame
to be measured is xed in place at the rear
assembly and the steering tube. Then the
gear crank area is deected to one side using
a dened force delivered by a pneumatic cy-
linder. As a second step rigidity measurement
of the steering pipe occurs through targeted
torsion of the steering head to the frame.
The rigidity values arise from the ratio of the
applied force and the resulting deection
of the frame area and are documented on
the test sticker in the operating instructions
enclosed.
