GENERAL
• The upside down-leg fork is specifically designed for Freeride,
Downhill and Slalom/Dirt jumper use. Damped by hydraulic
cartridges and sprung by a mechanical coil spring system.
• Spring pre-load adjustment (in both legs) and rebound damping
(right leg only) controlled via external top leg adjuster.
• The left leg is also damped by a hydraulic cartridge with a control
knob limiting leg rebound (ECC).
• Outer sliders criogenically secured to the steering crown. The
system gives the fork unmatched structural strength.
• Stanchions are integral with wheel shaft pinch bolts.
• Stanchions are guided by special long-life bushes inside the
sliders. Bushes can be easily reached for servicing.
• Parts subjected to friction are cooled and lubricated by specially
formulated oil.
• Left wheel shaft pinch bolt comes with brake caliper adapter.
• Axle support is the same drop-out design as in motorbikes,
having advanced wheel shaft with twin screw securing wheel
shaft onto both wheel shaft pinch bolts.
• Wheel shaft (20 mm diam.) available on request.

INSTRUCTIONS
GENERAL RULES
1.Where specified, assemble and disas-
semble the suspension system using 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 specific seal oil.
5.Always grease the conic seal rings be-
fore 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.

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
Assembling the brake caliper onto the wheel
shaft pinch bolt 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.
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.

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.
Polished
forks should be cleaned with
bodywork
polish
at regular intervals in
order to preserve their original finish.
 FITTING WHEEL
• Insert the complete wheel assembly be-
tween the legs and fit the wheel shaft
(32A)
into the wheel shaft pinch bolt
from the right hand side; push down until
it stops against the wheel hub.
• Tighten the wheel shaft screw
(32B)
onto the LH to the specified torque.
• Compress the fork several times so the
legs will become properly seated onto
wheel shaft. Lock the screws
(29)
in the
wheel shaft pinch bolts to the specified
torque.
