Fork's external components

Apart from a few exceptions, the new
MARZOCCHI fork designs consists of two main
assemblies: the stanchion tubes / steering
crown assembly (which are assembled through
a cryogenic process called "cryofit" for a stiff and
undetachable fit) and the magnesium-molded
sliders/arch monolith assembly.
The materials used are the BAM® aluminium
from the aerospace industry and magnesium;
these are lightweight materials that help reduce
the fork's weight.
A
The system for securing the wheel axle to the
fork sliders can be standard, with traditional
advanced dropouts (A) or with the QR20 Plus
system (B).
Forks using this system (B) must use a suitable
hub with 110 mm width spacing and a 20 mm
wheel axle.
QR20 Plus 2003: is the new, sophisticated
version of the QR20 system that fully wraps the
20 mm wheel axle, for maximum stiffness, while
still providing an easy way to remove the wheel.
The new QR20 Plus 20 mm axle system uses a
forged aluminium hinge that is permanently
attached to the magnesium sliders to clamp the
axle. The forged aluminium quick-release lever
makes opening and closing the flap routine.
The 20 mm wheel axle used in this system can
B
be the quick-release type or the bolt-on type.
The upside down forks (Shiver SC and Shiver
DC) are provided with a wheel fastening system
originating from the motorcycle application,
using a 20 mm axle (C).
FENDER: Marzocchi offers an integrated fender
option for the new Z1's, DJ's, Super T Pro and
Jr T's. It mounts to the underside of the crown to
help protect the rider against debris from the
front tire.
