Spindles

There is a massive
line of stub axles available for all classes. The difference in
the models being through the length, caster, geometry
of the rose joint attachment plate and for the various categories
that use front brakes. There are traditionally two designs to
mount the stub axle to the chassis.
The first being the classic style attaching the stub axle to the
C on the chassis, the other being the inverted system.
The inverted style has been achieved with a microfusion process
allowing for an interchangeable shaft with other shafts of different
lengths or rigidity.
