Technical information
2.1.3 Wheel axle securing system
The system for securing the wheel axle to the
fork sliders can be standard, with traditional
advanced 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, for
maximum stiffness, while still providing an easy
way to remove the wheel.
The new QR20 Plus 20 mm axle system is
available in two different versions, both using a
forged aluminium hinge that is attached to the
lower magnesium slider. The forged aluminium
lever can be the quick-release one, which
makes opening and closing the flap routine, or it
can be “with bolt”, where the clamping is made
via a screw tightening.
The 20 mm wheel axle used in both QR20 Plus
systems can be the quick-release type or the
bolt-on type.
The upside down forks (Shiver SC and Shiver
DC), as well as the models created for more
intensive use (888 Series and Monster Series)
are provided with a wheel fastening system
originating from the motorcycle application,
using a 20 mm axle.
