2.2 Fork’s internal components and
fork’s operation
Inside MARZOCCHI forks you will find coil
springs or air as a spring system.
The damping load that is generated during the
fork legs compression and rebound, can be
adjusted by cartridges, controlled by external
adjusters, or by special hydraulic valve pumping
rods, which operate according to compression
speed (Speed Sensitive Valving).
Pumping rods can be controlled by external or
internal adjusters, or they can have a fixed
setting.
Cartridges and pumping rods are fully plunged
in oil (Open Bath System). This system provides
proper lubrication and cooling of the inner sliding
parts; furthermore, the oil volume works as a
damping and setting element.
The Open Bath system reduces the
maintenance frequency compared to a sealed
cartridge system.
Stanchion tubes are guided in the sliders by two
teflon-coated bushings, free from static friction.
The seal system prevents oil leaks and
contamination from particles entering the fork. It
uses a special dual-lip oil seal and a dust seal at
the top of each slider.
You will find here below the different fork
damping systems:
ECC5 : the new Extension Control Cartridge
offers on-the-fly adjustment of the rebound
damping with a 5-position clicker. Use the fast
rebound position for downhilling, the 3 middle
positions for race start sprints and rough
climbing and the fully closed ECC position for
steep dirt switchback climbs or Marathon style
road climbs.
ETA : the new Extension Travel Adjustment locks
down the rebound damping like the standard
ECC, but still allows 25 - 30 mm of travel.
HSCV : the High-Speed Compression Valve
(HSCV) allows lighter damping for better trail
sensitivity but still resists bottoming. It is the best
way to provide a controlled damping
environment for consistent and perfect damping.
The moving valve on the shaft controls rebound
and low-speed compression damping. The
special valve in the bottom of the cartridge
(HSCV), takes the edge of any hard hit to
maintain control.
SSV : the Speed Sensitive Valve (SSV) uses 5
valve circuits to control damping rates based on
the fork’s compression and rebound speed as
well as the fork’s position in the travel.
SSVF : The latest version of our Speed Sensitive
Valve has a new Floating valve and spring
design. It incorporates a spring-loaded valve,
which is more responsive and uses an external
rebound adjuster.
