GENERAL
• The fork is sprung by a mechanical coil system and uses
hydraulic rebound damping for Freeride use.
• Rebound damping is controlled by pumping rods fixed to the
bottom of each slider; it can also be adjusted from the inside of
the stanchions.
• Spring pre-load adjustment controlled via external adjuster on
stanchion plugs.
• Stanchions fitted into lower Crown by cryofit technique. Full
length bushings guarantee superior rigidity.
• Sliders and arch are an integral assembly for reduced weight
and improved rigidity.
• Parts subjected to friction are cooled and lubricated by a
specially formulated oil.

GENERAL RULES
1.Where specified, assemble and disas-
semble the shock absorption system us-
ing the
M
ARZOCCHI
special tools only.
2.On reassembling the suspension system,
always use new seals.
3.Clean all metal parts with a special,
preferably biodegradable solvent, such
as trichloroethane or trichloroethylene.
4.Before reassembling, lubricate all parts
in contact with each other using silicone
fat spray or a specific oil for seals.
5.Always grease the lip seal rings before
reassembling.
6.Use wrenches with metric size only.
Wrenches with inch size might damage
the fastening devices even when their
size is similar to that of the wrenches in
metric size.
FAILURES, CAUSES AND REMEDIES
This paragraph reports some failures that may occur when using the fork. It also indicates possible causes and suggests a remedy.
Always refer to this table before doing any repair work.

RECOMMENDATIONS FOR
MAINTENANCE
M
ARZOCCHI
forks are based on advanced
technology, supported by year-long experi-
ence in the field of professional mountain
biking. In order to achieve best results, we
recommend to check and clean the area
below the dust seal and the stanchion tube
after each use and lubricate with silicone
oil.
In general,
M
ARZOCCHI
forks can offer top
performance from the start. However, in
some cases a short running-in period is
required (5-10 hours) for inner adjustments.
This running-in period will make fork life
longer and ensure fork top performance
over time.
INSTALLATION
Installing the fork on a bicycle is a very
delicate operation that should be carried
out with extreme care. The installation should
always be checked by one of our Technical
Service Centers.
DISC BRAKE SYSTEM ASSEMBLY
WARNING:
If a disc brake system
is installed, it is absolutely forbidden
to loosen and remove original brake sup-
ports fixing pins. In fact, apart from retain-
ing Cantilever or V-brake levers, they also
play an important role in securing slider
bottom to slider-arch monolith. If needed,
replace these pins with screws (part no.
532979QF
) available as spare parts.
Tighten the above screws to 10 Nm.

WARNING:
Steer tube/headset
mounting and adjustment must be
carried out in compliance with the headset
manufacturer’s instructions. Improper in-
stallation may jeopardize the safety of the
rider.
To replace it, contact one of our Technical
Service Centers with the required tools.
IMPORTANT:
screw and pin threading is
treated to ensure hydraulic seal. Never
reuse screws and pins which have been
removed.
WARNING:
In case of improper
installation of the steer tube into the
crown, the rider might lose control of his/
her bicycle, thus jeopardizing his/her safety.
IMPORTANT:
change oil at least every
100 working hours.
Assembling the brake caliper onto the slider
is a very delicate operation that should be
carried out with extreme care.
Improper assembly might overstress the
caliper supports which might break.
When installing the disc brake system, be
sure to properly follow the instructions given
by the manufacturer.
Polished
forks should be cleaned with
bodywork
polish
at regular intervals in
order to preserve their original finish.
