2 TECHNICAL INFORMATION
2.1 Fork’s external components
The MY 2004 MARZOCCHI Premium
Suspension forks range includes many different
models, having from 28 to 32 mm legs diameter
and travels up to 150 mm. Apart from a few
exceptions, the MARZOCCHI Premium
Suspension forks range consists of two main
assemblies:
• the stanchion tubes / steering crown
assembly, which are assembled under
pressure.
• the magnesium-casted sliders/arch monolith
assembly.
The main components are made of aluminium
alloy or magnesium; these are lightweight alloys
that help reducing the fork’s weight.
2.1.1 Fender
MARZOCCHI offers the option of the integrated
fender for all 32 mm diameter legs forks. The
fender mounted to the underside of the crown
helps protecting the rider against debris from the
front tire.
2.1.2 Wheel axle securing system
The system for securing the wheel axle to the
fork sliders can be standard, with traditional
dropouts or with the QR20 Plus system.
Forks using this system must have a suitable
hub with 110 mm width spacing and a 20 mm
wheel axle.
The MARZOCCHI QR20 Plus system: it is the
new, sophisticated version of the QR20 system
that fully wraps the 20 mm wheel axle, offering
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 attached to the
lower part of the slider. The quick-release forged
aluminium lever makes opening and closing the
flap routine. The 20 mm wheel axle can be the
quick-release type or the bolt-on type.
