INSTRUCTIONS FOR USE OF Ø45USD FORK
GENERAL
Remote hydraulic fork with reversed legs with static load spring and cartridge
multivalve damping system. During the compression stage, the hydraulic
damping is performed by a special valve at the bottom of each, whereas
during the rebound stage it is performed by a cartridge inside each stanchion.
Each fork leg is equipped with an outer adjuster for
compression and rebound. Bleeder screw on the top plug of each leg.
Sliding bushing for floating damping rod.
STANCHION TUBES: special high resistance stainless steel, surface chrome
plating.
SLIDER: aluminum alloy, CNC machined.
SLIDING BUSHINGS: Teflon, free from static friction.
SEALS: computer designed oil seals ensure the highest seal during
compression and minimum friction during rebound
SPRINGS: stainless steel with steady pitch, available in different lengths for
different static loads (see table).
OIL: MARZOCCHI SAE 7.5 Ref. 550013. Special formula with no foam
building. It keeps the viscosity features unchanged in every working condition:
free from static friction. For particularly cold climates use oil “MARZOCCHI -
SAE 5 Ref. 550003.
SPRING TABLE
The static load of the fork is determined by the spring, positioned at the top of
each leg: by changing either spring features or pre-load sleeve length a
different suspension behavior is obtained without changing the hydraulic
features. The following table describes the “pipe” kit available as
spare part.
